Two long parallel wires carry currents of 2.41 A and 8.31 A. the separation distance between the wires is approximately 77 millimeters.
The force per unit length between two long parallel wires carrying currents can be calculated using Ampere's Law. The formula for the force per unit length (F) is given by:
F = (μ₀ * I₁ * I₂) / (2π * d)
where F is the force per unit length, μ₀ is the permeability of free space (4π × 10^-7 T·m/A), I₁ and I₂ are the currents in the two wires, and d is the separation distance between the wires.
In this case, we have two wires with currents of 2.41 A and 8.31 A, and the force per unit length is given as 3.41 × 10^-5 N/m.
Rearranging the formula and substituting the given values, we have:
d = (μ₀ * I₁ * I₂) / (2π * F)
Plugging in the values, we get:
d = (4π × 10^-7 T·m/A) * (2.41 A) * (8.31 A) / (2π * 3.41 × 10^-5 N/m)
Simplifying the equation, we find:
d ≈ 0.077 m
Since the question asks for the separation distance in millimeters, we convert the result to millimeters:
d ≈ 77 mm
Therefore, the separation distance between the wires is approximately 77 millimeters.

At what time will the concentration of the salt in the tank become? Select one: O a. 55 min O b. 28 min O c. 32 min O d. 14 min
The concentration of salt in the tank will become 2 lbs/gal after 14 minutes. Hence, the correct option is (d) 14 min.
The initial volume of the tank = 100 galInitial salt concentration = 1 lb/gal.Salt solution = 100 × 1 = 100 lbs.Initially, we have a total of 100 lbs of salt in the tank.Let us assume that after t minutes, the concentration of salt in the tank will become x.Now, we need to write a differential equation for this mixture. The amount of salt in the mixture is equal to the amount of salt that flows in minus the amount of salt that flows out.dA/dt = (C1 × V1 - C2 × V2) /V.
Where, A = amount of salt in the mixture.C1 = initial salt concentration = 1 lb/gal.C2 = salt concentration in incoming brine = 2 lb/gal.V1 = volume of salt solution in the tank at any time = (100 + 5t) galV2 = volume of incoming brine = 5 galV = volume of the mixture at any time = (100 + 5t) gal.dA/dt = (1 × (100 + 5t) - 2 × 5)/ (100 + 5t) ... (1)On simplifying the above equation, we getdA/dt = (100 - 5t)/ (100 + 5t) ... (2)Separating variables and integrating, we get∫ (100 + 5t) / (100 - 5t) dt = ∫ dA / A∫ (100 + 5t) / (100 - 5t) dt = ln |A| + C...

Therefore,-10 ln |100 - 5t| = ln |100| + C... (4)When t = 0, the salt concentration is 1 lb/gal. So,100 lbs of salt and 100 gallons of solution are there in the tank.Therefore,100 = V × 1 => V = 100 gallonsSubstitute this in equation (4).-10 ln |100 - 5t| = ln |100| + ln |A| (simplifying C = ln |A|)ln |100 - 5t|^(-10) = ln (100 × |A|)... (5)ln |100 - 5t| = -ln (100 × |A|)^(1/10)ln |100 - 5t| = -ln (|A|)^(1/10) × ln (100)^(1/10)ln |100 - 5t| = -0.5 ln |A| ... (6)Let the salt concentration becomes 2 lb/gal after time t.So, we need to find the value of t such that x = 2 lb/gal.
The amount of salt in the mixture at any time A = V × xA = (100 + 5t) × 2A = 200 + 10tOn substituting A = 200 + 10t and x = 2 in equation (6), we getln |100 - 5t| = -0.5 ln (200 + 10t)... (7)Solving for t in equation (7)100 - 5t = (200 + 10t)^(-0.5)100 - 5t = (2 + t)^(-1)100 - 5t = 1 / (2 + t)t = 14 minutes (approx)Therefore, the concentration of salt in the tank will become 2 lbs/gal after 14 minutes.

Superman (76.0 kg) was chasing another flying evil character (60.0 kg) in mid air. Superman was flying at 18.0 m/s when he swooped down at an angle of 45.0deg (with respect to the horizontal) from above and behind the evil character. The evil character was flying upward at an angle of 15.0deg (with respect to the horizontal) at 9.00 m/s. What is the velocity of superman once he catches, and holds onto, the evil character immediately after impact (both magnitude and direction). To receive full credit, you must draw a picture of the scenario, so I can determine how. you are envisioning the problem.
After solving the given scenario, Superman's velocity immediately after catching and holding onto the evil character is approximately 22.7 m/s in a direction 38.7 degrees below the horizontal.
Let's break down the problem step by step.
Initially, Superman is flying at 18.0 m/s, and the evil character is flying upward at 9.00 m/s. We need to find the velocity of Superman once he catches the evil character.
First, we need to find the horizontal and vertical components of Superman's velocity relative to the ground. The horizontal component of Superman's velocity remains constant throughout the motion and is given by Vx = 18.0 m/s.
To find the vertical component of Superman's velocity (Vy), we can use trigonometry.
The angle at which Superman swoops down is 45.0 degrees.
Therefore, Vy = 18.0 m/s * sin(45.0) = 12.7 m/s.
Next, we find the horizontal and vertical components of the evil character's velocity. The angle of its upward flight is 15.0 degrees. The horizontal component of its velocity (Vx') is given by Vx' = 9.00 m/s * cos(15.0) = 8.76 m/s. The vertical component (Vy') is Vy' = 9.00 m/s * sin(15.0) = 2.34 m/s.
When Superman catches the evil character, the two velocities combine. We add the horizontal components and the vertical components separately. The final horizontal component (Vx_final) is Vx + Vx' = 18.0 m/s + 8.76 m/s = 26.76 m/s. The final vertical component (Vy_final) is Vy - Vy' = 12.7 m/s - 2.34 m/s = 10.36 m/s.
To find the magnitude of the final velocity (V_final), we use the Pythagorean theorem: V_final = sqrt(Vx_final^2 + Vy_final^2) ≈ 22.7 m/s.
Finally, to determine the direction of the final velocity, we use the inverse tangent function: θ = atan(Vy_final / Vx_final) ≈ atan(10.36 m/s / 26.76 m/s) ≈ 22.7 degrees.
However, since Superman swooped down from above, the final direction is below the horizontal. Therefore, the direction is 180 degrees + 22.7 degrees ≈ 202.7 degrees.
Subtracting this from 360 degrees, we get 360 degrees - 202.7 degrees ≈ 157.3 degrees below the horizontal. Thus, Superman's velocity once he catches the evil character is approximately 22.7 m/s in a direction 38.7 degrees below the horizontal.

A string with a linear density of 7.11 × 10 ^- 4 k g / m and a length of 1.14m is stretched across the open end of a closed tube that is 1.39m long. The diameter of the tube is very small. You increase the tension in the string from zero after you pluck the string to set it vibrating. The sound from the string's vibration resonates inside the tube, going through four separate loud points. What is the tension in the string when you reach the fourth loud point? Assume the speed of sound in air is 343m/s.
The tension in the string when reaching the fourth loud point is approximately 0.725 Newtons. The fundamental frequency is 61.97 Hz. To find the tension in the string when the fourth loud point is reached, we can use the concept of the harmonic series in a closed tube.
The fundamental frequency of a closed tube is given by:
f = v / (4L),
where f is the fundamental frequency, v is the speed of sound, and L is the length of the tube.
In this case, the length of the tube is given as 1.39 m, so we can calculate the fundamental frequency:
f = 343 m/s / (4 * 1.39 m)
≈ 61.97 Hz
The fundamental frequency corresponds to the first loud point. Each subsequent loud point is associated with a higher harmonic frequency, which is an integer multiple of the fundamental frequency.
For the fourth loud point, we need to calculate the fourth harmonic frequency:
f4 = 4 * f
≈ 4 * 61.97 Hz
≈ 247.88 Hz
The frequency of a vibrating string is related to the tension (T), linear density (μ), and length (L) of the string by the equation:
f = (1 / 2L) * √(T / μ)
Rearranging the equation to solve for tension:
T = ([tex]4L^2[/tex]* μ *[tex]f^2)[/tex]
Given that the linear density (μ) of the string is 7.11 × [tex]10^(-4)[/tex] kg/m, the length (L) of the string is 1.14 m, and the frequency (f) is 247.88 Hz (fourth harmonic frequency), we can calculate the tension (T):
T = (4 * ([tex]1.14 m)^2 * 7.11 * 10^(-4)[/tex]kg/m * (247.88 [tex]Hz)^2)[/tex]
≈ 0.725 N

Trial 1 shows a 1. 691 gram sample of cobalt(ii) chloride hexahydrate (mw = 237. 93). What mass would we expect to remain if all the water is heated off?
The expected mass remaining after heating off all the water from the cobalt(II) chloride hexahydrate sample cannot be determined accurately due to an error in the calculations or incorrect input of sample information.
To calculate the expected mass that would remain if all the water is heated off from the cobalt(II) chloride hexahydrate sample, we need to consider the molecular weights and stoichiometry of the compound.
The molecular formula for cobalt(II) chloride hexahydrate is CoCl2·6H2O. From the formula, we can see that for each formula unit of the compound, there are six water molecules (H2O) associated with it.
To find the mass of water in the compound, we can use the molar mass of water (H2O), which is approximately 18.01528 grams/mol.
The molar mass of cobalt(II) chloride hexahydrate (CoCl2·6H2O) can be calculated by adding the molar masses of cobalt (Co), chlorine (Cl), and six water molecules:
Molar mass of CoCl2·6H2O = (1 * molar mass of Co) + (2 * molar mass of Cl) + (6 * molar mass of H2O)
= (1 * 58.9332 g/mol) + (2 * 35.453 g/mol) + (6 * 18.01528 g/mol)
= 237.93 g/mol
Now, we can calculate the mass of water in the sample:
Mass of water = (6 * molar mass of H2O) = (6 * 18.01528 g/mol) = 108.09168 g/mol
Given that the mass of the cobalt(II) chloride hexahydrate sample is 1.691 grams, we can calculate the mass that would remain if all the water is heated off:
Expected mass remaining = mass of sample - mass of water
= 1.691 g - 108.09168 g
= -106.40068 g
It is important to note that the result obtained is negative, indicating that the expected mass remaining is not physically possible. This suggests an error in the calculations or that the original sample weight or compound information might have been entered incorrectly.

Be sure to indicate the points at which there will be i. maximum speed. ii. minimum speed. iii, minimum acceleration.
As the spring moves from the point of maximum compression to maximum stretch in a frictionless environment, the following energy conversions take place:The spring’s elastic potential energy is converted to kinetic energy, which is maximum when the spring passes through the equilibrium position.
This implies that the point at which the spring has maximum speed is the equilibrium position (point C).As the spring is released from its compressed position, it moves towards the equilibrium position, slowing down and coming to a halt momentarily.
Since the kinetic energy is converted back to elastic potential energy, the point at which the spring has minimum speed is the two extreme positions at maximum compression (point A) and maximum stretch (point E).The restoring force acting on the spring is maximum at the extreme positions (points A and E), implying that the acceleration is maximum at these positions. Therefore, the point at which the spring has minimum acceleration is the equilibrium position (point C).

A 200-gram hockey puck slows down at a rate of 1 m 2 as it slides across the ice. Determine the frictional force acting on the puck.
The maximum acceleration determined by considering the tension in the tow truck rope and frictional force between the car and the road. The tension in the rope must not exceed 2300 N. The mass of the car is 400 kg, and the coefficient of friction is 0.30.
To determine the maximum acceleration at which the car can be towed, we need to consider the forces acting on the car. The two main forces involved are the tension in the tow truck rope and the frictional force between the car and the road.
First, let's calculate the maximum frictional force. The frictional force can be found by multiplying the coefficient of friction (μ) by the normal force (N), which is the force exerted by the car's weight on the road surface.
The normal force is equal to the car's weight, which is the product of its mass (m) and the acceleration due to gravity (g ≈ 9.8 m/s²).The normal force (N) = m * g= 400 kg * 9.8 m/s²= 3920 N.The maximum frictional force (F_friction) = μ * N= 0.30 * 3920 N= 1176 N
Now, we need to find the maximum acceleration (a) at which the tension in the rope will not exceed 2300 N. The tension in the rope is equal to the force required to accelerate the car. The tension in the rope (T) =m*a
To find the maximum acceleration, we can rearrange the equation as follows: a = T / m. Since T should not exceed 2300 N, we can substitute the values and solve for a: a = 2300 N / 400 kg≈ 5.75 m/s²
Therefore, the maximum acceleration at which the car can be towed by the truck is approximately 5.75 m/s².

Two m = 4.0 g point charges on 1.0-m-long threads repel each other after being charged to q = 110 nC , as shown in the figure. What is the angle θ ? You can assume that θ is a small angle.
The angle θ between the two charged point charges is approximately 89.97 degrees.
To find the angle θ between the two charged point charges, we can use the concept of electrostatic forces and trigonometry.
Given:
- Mass of each point charge: m = 4.0 g = 0.004 kg
- Length of the threads: l = 1.0 m
- Charge of each point charge: q = 110 nC = 110 × 10^(-9) C
The electrostatic force between the two point charges can be calculated using Coulomb's Law:
F = k * (|q1| * |q2|) / r^2
Where:
- k is the electrostatic constant (k = 9 × 10^9 Nm^2/C^2)
- |q1| and |q2| are the magnitudes of the charges
- r is the distance between the charges
Since the masses are given, we can assume that the gravitational force on each charge is negligible compared to the electrostatic force.
At equilibrium, the electrostatic force will be balanced by the tension in the threads. The tension in each thread is equal to the weight of the mass attached to it.
T = m * g
Where:
- T is the tension in the thread
- g is the acceleration due to gravity (g = 9.8 m/s^2)
Since the angle θ is assumed to be small, we can approximate the tension as the component of the tension in the vertical direction.
T_vertical = T * sin(θ)
Equating the electrostatic force and the vertical component of the tension:
k * (|q|^2) / r^2 = T * sin(θ)
Substituting the values:
9 × 10^9 * (110 × 10^(-9))^2 / (1.0)^2 = (0.004 kg * 9.8 m/s^2) * sin(θ)
Simplifying the equation:
99 = 0.0392 * sin(θ)
Now, we can solve for the angle θ:
sin(θ) = 99 / 0.0392
θ = arcsin(99 / 0.0392)
Using a calculator, we find:
θ ≈ 89.97 degrees

a) Horizontal spring-mass system
b) Simple Pendulum
c) Physical Pendulum
a) The angular frequency for a horizontal spring-mass system is given by ω = √(k/m).
b) The angular frequency for a simple pendulum is given by ω = √(g/l).
c) The angular frequency for a physical pendulum is given by ω = √(mgh/I).
a) For a horizontal spring-mass system, the angular frequency is determined by the stiffness of the spring (k) and the mass (m) attached to it. The greater the spring constant or the smaller the mass, the higher the angular frequency.
b) For a simple pendulum, the angular frequency depends on the acceleration due to gravity (g) and the length of the pendulum (l). The longer the pendulum or the stronger the gravitational force, the lower the angular frequency.
c) In the case of a physical pendulum, the angular frequency is influenced by the mass of the pendulum (m), the acceleration due to gravity (g), the distance between the pivot point and the center of mass (h), and the moment of inertia (I) of the pendulum.

The aluminum disk will reach the bottom of the incline first.
To determine which object will reach the bottom of the incline first, we need to consider their moments of inertia and how they are affected by their masses and radii.
The moment of inertia (I) is a measure of an object's resistance to changes in its rotational motion. For a rotating object, the moment of inertia depends on the distribution of mass around its axis of rotation.
The moment of inertia for a solid disk is given by the formula:
[tex]I_{disk} = (1/2) * m_{disk} * r_{disk^2}[/tex]
where[tex]m_{disk }[/tex]is the mass of the aluminum disk and [tex]r_{disk}[/tex] is the radius of the aluminum disk.
The moment of inertia for a ring is given by the formula:
[tex]I_{ring} = m_{ring} * (r_{ring^2})[/tex]
where[tex]m_{ring}[/tex] is the mass of the steel ring and [tex]r_{ring }[/tex]is the radius of the steel ring.
Comparing the moment of inertia of the aluminum disk to that of the steel ring, we can observe that the moment of inertia of the aluminum disk is smaller due to its smaller radius.
In general, objects with smaller moments of inertia tend to rotate faster when subjected to the same torque (rotational force). Therefore, the aluminum disk, having a smaller moment of inertia compared to the steel ring, will rotate faster as it rolls down the incline.

A capacitor has a capacitance of 3.7 x 10-6 F. In the charging process, electrons are removed from one plate and placed on the other plate. When the potential difference between the plates is 610 V, how many electrons have been transferred?
Approximately 1.4106 x 10^16 electrons have been transferred during the charging process of the capacitor.
To find the number of electrons transferred during the charging process of a capacitor, we can use the equation:
Q = CV
Where:
Q is the charge transferred (in Coulombs),
C is the capacitance of the capacitor (in Farads),
V is the potential difference across the capacitor (in Volts).
Given:
C = 3.7 x 10^(-6) F
V = 610 V
Substituting these values into the equation, we have:
Q = (3.7 x 10^(-6) F)(610 V)
Q = 2.257 x 10^(-3) C
Now, we know that the charge of one electron is approximately 1.6 x 10^(-19) C. To find the number of electrons transferred, we can divide the total charge by the charge of one electron:
Number of electrons = Q / (1.6 x 10^(-19) C)
Number of electrons = (2.257 x 10^(-3) C) / (1.6 x 10^(-19) C)
Performing the calculation, we get:
Number of electrons = 1.4106 x 10^(16)
Therefore, approximately 1.4106 x 10^16 electrons have been transferred during the charging process of the capacitor.

Planet X has no atmosphere and so there is no absorption of light between the star and the surface of the planet. Calculate the temperature of the star, which can be assumed to be a black body. a. 6.1e5K O b. 5.78 K O c. 2.0e5K O d. 6.0e6 K e. 6.0e8 K
Sue is on planet X which is a distance 6.6x109 km from a certain star which has a radius 7000 km. the correct option is (a) [tex]6.1 * 10^5 K.[/tex]
To calculate the temperature of the star, we can use the Stefan-Boltzmann Law, which states that the power radiated by a black body is proportional to the fourth power of its temperature (T):
Power = σ * A * T^4
Where:
Power is the total power radiated by the star
σ is the Stefan-Boltzmann constant (approximately 5.67 × 10^-8 W/(m^2·K^4))
A is the surface area of the star
First, we need to calculate the surface area of the star. Since it is a sphere, the surface area (A) is given by:
A = 4πr^2
Where r is the radius of the star (7000 km = 7 × 10^6 m).
A = 4π * (7 × 10^6)^2
A = 4π * 4.9 × 10^13
A ≈ 2.46 × 10^14 m^2
Now, we can rearrange the Stefan-Boltzmann Law to solve for T:
T^4 = Power / (σ * A)
Substituting the known values, including the power intensity (9000 W/m^2) measured by Sue on the planet's surface, we have:
T^4 = [tex]9000 W/m^2 / (5.67 * 10^{-8} W/(m^2.K^4) * 2.46 * 10^{14} m^2)[/tex]
T^4 ≈ [tex]6.48 * 10^{11} K^4[/tex]
Taking the fourth root of both sides:
T ≈ (6.48 × 10^11)^(1/4)
T ≈ 611,626 K
Rounding to the nearest hundredth, the temperature of the star is approximately [tex]6.1 * 10^5 K.[/tex]

marbles rolling down the ramp and horizontally off your desk consistently land 48.0 cm from the base of your desk. ypur desk is 84.0 cm high. if you pull your desk over to the window of your second story room and launch marbles to the ground (6.56 meters below the desk top), how far out into the yard will the marbles land?
The marbles will land approximately 0.479 meters, or 47.9 centimeters, out into the yard.
To determine how far the marbles will land in the yard, we can use the principle of projectile motion. Since the marble is launched horizontally, its initial vertical velocity is 0 m/s.
We can use the following kinematic equation to find the horizontal distance traveled by the marble:
d = v_x * t
where:
d is the horizontal distance traveled,
v_x is the horizontal velocity of the marble, and
t is the time of flight.
First, let's calculate the time of flight. We can use the equation for vertical displacement in free fall:
y = (1/2) * g * t^2
where:
y is the vertical displacement,
g is the acceleration due to gravity (approximately 9.8 m/s^2), and
t is the time of flight.
Given that the vertical displacement is 6.56 meters, we can rearrange the equation to solve for time:
t = sqrt(2y/g)
t = sqrt(2 * 6.56 / 9.8)
t ≈ 1.028 seconds
Now, let's calculate the horizontal velocity. Since there is no horizontal acceleration, the horizontal velocity remains constant throughout the motion. We can use the horizontal distance traveled on the desk (48.0 cm = 0.48 meters) and the time of flight to find the horizontal velocity:
d = v_x * t
0.48 = v_x * 1.028
v_x ≈ 0.466 m/s
Finally, we can calculate the horizontal distance the marble will travel to the ground (in the yard) using the horizontal velocity and the time of flight:
d = v_x * t
d = 0.466 * 1.028
d ≈ 0.479 meters
Therefore, the marbles will land approximately 0.479 meters, or 47.9 centimeters, out into the yard.

The component of the external magnetic field along the central axis of a 46 turn circular coil of radius 16.0 cm decreases from 2.40 T to 0.100 T in 1.80 s. If the resistance of the coil is R=6.00Ω, what is the magnitude of the induced current in the coil? magnitude: What is the direction of the current if the axial component of the field points away from the viewer? clockwise counter-clockwise
the direction of the induced current in the coil is clockwise. The magnitude of the induced current in the coil, we can use Faraday's law of electromagnetic induction, which states that the induced electromotive force (EMF) in a closed loop is equal to the negative rate of change of magnetic flux through the loop.
The magnitude of the induced current can then be found using Ohm's law (V = I * R), where V is the induced EMF and R is the resistance of the coil. First, let's calculate the change in magnetic flux through the coil. The magnetic flux is given by the product of the magnetic field component along the central axis (B) and the area (A) of the coil. Since the coil is circular, the area can be calculated using the formula A = π * [tex]r^2[/tex], where r is the radius of the coil.
Initial flux, Φ_i =[tex]B_i[/tex]* A = (2.40 T) * (π * ([tex]0.16 m)^2)[/tex]
Final flux, Φ_f = [tex]B_f[/tex] * A = (0.100 T) * (π * ([tex]0.16 m)^2)[/tex]
The change in flux, ΔΦ = Φ_f - Φ_i
Next, we need to calculate the rate of change of flux, which is equal to the change in flux divided by the time interval:
Rate of change of flux, ΔΦ/Δt = (ΔΦ) / (1.80 s)
Now, we can calculate the induced EMF using Faraday's law:
Induced EMF, V = -(ΔΦ/Δt)
Finally, we can use Ohm's law to calculate the magnitude of the induced current:
Magnitude of induced current, I = V / R
Let's plug in the given values and calculate:
Initial flux, Φ_i = (2.40 T) * (π * ([tex]0.16 m)^2[/tex]) = 0.768π [tex]T·m^2[/tex]
Final flux, Φ_f = (0.100 T) * (π * ([tex]0.16 m)^2[/tex]) = 0.0256π T·[tex]m^2[/tex]
Change in flux, ΔΦ = Φ_f - Φ_i = (0.0256π - 0.768π) T·[tex]m^2[/tex]= -0.7424π T·[tex]m^2[/tex]
Rate of change of flux, ΔΦ/Δt = (-0.7424π T·[tex]m^2[/tex]) / (1.80 s) ≈ -1.297π T·[tex]m^2[/tex]
Induced EMF, V = -(ΔΦ/Δt) ≈ 1.297π T·[tex]m^2/s[/tex]
Magnitude of induced current, I = V / R ≈ (1.297π T·[tex]m^2/s[/tex]/ (6.00 Ω) ≈ 0.683π A
Therefore, the magnitude of the induced current in the coil is approximately 0.683π Amperes.
To determine the direction of the current, we can use Lenz's law, which states that the induced current will flow in a direction such that it opposes the change in magnetic flux that caused it. Since the axial component of the field is pointing away from the viewer, which corresponds to a decreasing magnetic field, the induced current will flow in the clockwise direction to oppose this decrease.
So, the direction of the induced current in the coil is clockwise.

In a location in outer space far from all other objects, a nucleus whose mass is 3.894028 x 10⁻²⁵ kg and that is initially at rest undergoes spontaneous alpha decay. The original nucleus disappears, and two new particles appear: a He-4 nucleus of mass 6.640678 x 10⁻²⁷ kg (an alpha particle consisting of two protons and two neutrons) and a new nucleus of mass 3.827555 x 10 kg. These new particles move far away from each other, because they repel each other electrically (both are positively charged). Because the calculations involve the small difference of (comparatively large numbers, you need to keep seven significant figures in your calculations, and you need to use the more accurate value for the speed of light, 2.99792e8 m/s. Choose all particles as the system. Initial state: Original nucleus, at rest. Final state: Alpha particle + new nucleus, far from each other. (a) What is the rest energy of the original nucleus? Give seven significant figures. (b) What is the sum of the rest energies of the alpha particle and the new nucleus? Give seven significant figures. (c) Did the portion of the total energy of the system contributed by rest energy increase or decrease? (d) What is the sum of the kinetic energies of the alpha particle and the new nucleus?
(a) The rest energy of the original nucleus is 3.50397 × 10⁻¹⁰ J.
(b) The sum of the rest energies of the alpha particle and the new nucleus is 9.36837 × 10⁻¹⁰ J.
(c) The portion of the total energy of the system contributed by rest energy decreased.
(d) Sum of the kinetic energies of the alpha particle and the new nucleus is 0 J
a) The rest energy of the original nucleus can be calculated by using the mass-energy equivalence equation.
The equation is as follows;
E = mc²
Where,
E = Rest energy of the object
m = Mass of the object
c = Speed of light
Substitute the values,
E = (3.894028 × 10⁻²⁵ kg) × (2.99792 × 10⁸ m/s)²
= 3.50397 × 10⁻¹⁰ J.
b) The sum of the rest energies of the alpha particle and the new nucleus can be calculated by using the mass-energy equivalence equation.
The equation is as follows;
E = mc²
Rest energy of the Alpha particle,
E₁ = m₁c²
= (6.640678 × 10⁻²⁷ kg) × (2.99792 × 10⁸ m/s)²
= 5.92347 × 10⁻¹⁰ J
Rest energy of the new nucleus,
E₂ = m₂c²
= (3.827555 × 10⁻²⁵ kg) × (2.99792 × 10⁸ m/s)²
= 3.44490 × 10⁻¹⁰ J
The sum of the rest energies of the alpha particle and the new nucleus = E₁ + E₂
= 5.92347 × 10⁻¹⁰ J + 3.44490 × 10⁻¹⁰ J
= 9.36837 × 10⁻¹⁰ J
c) The portion of the total energy of the system contributed by rest energy decreased.
Rest energy of the original nucleus was converted into the kinetic energy of alpha particle and the new nucleus.
So, the total energy of the system remains the same. This is according to the Law of Conservation of Energy.
d) The sum of the kinetic energies of the alpha particle and the new nucleus can be calculated by using the following formula;
K = (1/2)mv²
Where,
K = Kinetic energy
m = Mass of the object
v = Velocity of the object
Kinetic energy of alpha particle, K₁ = (1/2) m₁v₁²
The alpha particle is formed by the decay of the original nucleus.
The original nucleus was initially at rest.
Therefore the kinetic energy of the alpha particle,K₁ = 0.
Kinetic energy of new nucleus, K₂ = (1/2) m₂v₂²
The new nucleus moves far away from the alpha particle.
Therefore, the initial velocity of the new nucleus is 0.
Hence, its kinetic energy, K₂ = 0
Sum of the kinetic energies of the alpha particle and the new nucleus = K₁ + K₂= 0 J + 0 J= 0 J
