Part A, we need to find the final velocity of the bullet-block combination immediately after the collision. In part B, we are asked to calculate the horizontal range x of the bullet-block combination when it hits the ground. Part C, we need to determine the speed of the bullet-block combination just before it hits the ground.

In Part A, we can apply the principle of conservation of momentum. Since the system is isolated, the momentum before the collision is equal to the momentum after the collision. By considering the momentum of the bullet and the block separately, we can find the final velocity of the combined system.

In Part B, we can determine the time it takes for the bullet-block combination to hit the ground by using the equation of motion in the vertical direction. The displacement is the height of the block, and the initial velocity is the final velocity found in Part A. With this time, we can then calculate the horizontal range x using the equation of motion in the horizontal direction.

The package takes approximately 0.00279 hours (10.04 seconds) to reach the ground. The horizontal displacement remains constant at 670 m, and the vertical displacement is determined by the equation t^2 = (2h) / g, resulting in a height of 500 m.

The punctual airplane releases a package at a fixed altitude and constant speed. The package reaches the ground at a specific point, and friction forces are disregarded.

Considering the given scenario, where the airplane is flying at a fixed altitude of 500 m with a constant speed of 240 km/h, it releases a package at time t = 0 when it passes vertically over the origin point O. The package's trajectory can be analyzed to determine its motion.

Since the package reaches the ground at point P with a distance OP of 670 m, we can infer that the horizontal displacement of the package, denoted as x, is 670 m. Since the airplane maintains a constant speed throughout, the horizontal velocity of the package, denoted as vx, will also be constant.

The time taken by the package to reach the ground can be calculated using the equation of motion: x = v*t, where x is the displacement, v is the velocity, and t is the time. Rearranging the equation, we have t = x / v. Substituting the given values, t = 670 m / (240 km/h) = 670 m / (240,000 m/h) = 0.00279 hours.

To determine the vertical motion of the package, we can use the equation of motion for constant acceleration: h = (1/2) * g * t^2, where h is the height, g is the acceleration due to gravity, and t is the time. Rearranging the equation, we have t^2 = (2h) / g. Substituting the given values, t^2 = (2 * 500 m) / (9.8 m/s^2) = 102.04 s^2.

Therefore, the package takes approximately 0.00279 hours (10.04 seconds) to reach the ground. The horizontal displacement remains constant at 670 m, and the vertical displacement is determined by the equation t^2 = (2h) / g, resulting in a height of 500 m. Neglecting friction forces, these calculations provide an understanding of the motion of the package released by the punctual airplane.

(a) Assuming that the electron and proton are separated by r = 1.0 x 10⁻¹⁰ m, calculate the magnitude (in N) of the electrostatic force attracting the particles to each other2.304N.(b)The electrostatic potential energy of a hydrogen atom is approximately -14.4 × 10^(19) eV.

(a) To calculate the magnitude of the electrostatic force between the electron and proton in a hydrogen atom, we can use Coulomb's law. Coulomb's law states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

Coulomb's law equation:

F = k × (|q₁| × |q₂|) / r^2

where F is the force, k is the electrostatic constant (9 × 10^9 N m²/C²), q₁ and q₂ are the magnitudes of the charges, and r is the distance between the charges.

In the case of a hydrogen atom, the charges involved are the charge of the electron (e = 1.6 × 10^(-19) C) and the charge of the proton (e = 1.6 × 10^(-19) C). The distance between them is given as r = 1.0 × 10^(-10) m.

Substituting the values into the equation:

F = (9 × 10^9 N m²/C²) × ((1.6 × 10^(-19) C) × (1.6 × 10^(-19) C)) / (1.0 × 10^(-10) m)²

F ≈ 2.304 N

Therefore, the magnitude of the electrostatic force attracting the electron and proton in a hydrogen atom is approximately 2.304 N.

(b) The electrostatic potential energy of a hydrogen atom can be calculated using the equation:

Potential energy = -k × (|q₁| * |q₂|) / r

In this case, we consider the potential energy of the electron and proton interaction.

Substituting the given values:

Potential energy = -(9 × 10^9 N m²/C²) × ((1.6 × 10^(-19) C) × (1.6 × 10^(-19) C)) / (1.0 × 10^(-10) m)

Potential energy ≈ -2.304 J

To convert the potential energy from joules (J) to electron volts (eV), we can use the conversion factor:

1 eV = 1.6 × 10^(-19) J

Converting the potential energy:

Potential energy = (-2.304 J) / (1.6 × 10^(-19) J/eV)

Potential energy ≈ -14.4 × 10^(19) eV

Therefore, the electrostatic potential energy of a hydrogen atom is approximately -14.4 × 10^(19) eV.

The problem involves two MOSFETs mounted on a common heatsink, and the goal is to determine the required thermal resistance of the heatsink.

Given the power dissipation and thermal resistance values of the MOSFETs, along with the maximum junction temperature and ambient temperature, the thermal circuit needs to be analyzed to find the required heatsink thermal resistance.

To analyze the thermal circuit and determine the required heatsink thermal resistance, we can start by visualizing the circuit as a thermal network. The key components in the circuit are the MOSFETs (M1 and M2), their junction-to-case thermal resistances (Rjc1 and Rjc2), the case-to-heatsink thermal resistances (Rcs1 and Rcs2), and the unknown heatsink thermal resistance (Rsa). We also have the maximum junction temperature (Tj1 = Tj2 = 180°C) and the ambient temperature (Ta = 40°C).By applying the thermal circuit equations, we can write the following expression to calculate Rsa:

Rsa = (Tj1 - Ta - Pd1 * (Rjc1 + Rcs1)) / Pd1

where Pd1 is the power dissipated by device M1 (16 W) and Rjc1 is the junction-to-case thermal resistance of M1 (4 K/W). We can substitute these values into the equation and solve for Rsa.

Similarly, for M2, we have:

Rsa = (Tj2 - Ta - Pd2 * (Rjc2 + Rcs2)) / Pd2

where Pd2 is the power dissipated by device M2 (24 W) and Rjc2 is the junction-to-case thermal resistance of M2 (2 K/W).

Once we have the values of Rsa from both equations, we can compare them and choose the larger value as the required heatsink thermal resistance to ensure proper heat dissipation and keep the MOSFETs within their maximum temperature limits.

In conclusion, by constructing the thermal circuit and applying the thermal equations, we can determine the required heatsink thermal resistance (Rsa) to keep the MOSFETs within their temperature limits. This ensures the reliable operation of the circuit under the given power dissipation and ambient temperature conditions. The thermal circuit analysis helps in understanding the heat flow and designing effective cooling solutions to maintain the components at safe operating temperatures.

A cyclotron is a device that is used to accelerate charged particles to high energies by the application of high-frequency radio-frequency (RF) electromagnetic fields.

It works on the principle of a charged particle moving perpendicular to a magnetic field line. When the particle moves perpendicular to the magnetic field lines, it experiences a force that makes it move in a circular path. The radius of a cyclotron can be calculated using the formula: r = mv/qB

where m is the mass of the particle, v is its velocity, q is its charge, and B is the magnetic field strength.

In this case, we are given that the protons are to be accelerated to energies of 36.0 MeV using a magnetic field of 5.18 T. The mass of a proton is 1.67 x 10⁻²⁷ kg, and its charge is 1.6 x 10⁻¹⁹ C.

The energy of the proton is given by E = mv²/2.

Solving for v, we get:v = √(2E/m) = √(2 x 36 x 10⁶ x 1.6 x 10⁻¹⁹/1.67 x 10⁻²⁷) = 3.02 x 10⁷ m/s

Substituting these values into the formula for r, we get:r = mv/qB = (1.67 x 10⁻²⁷ x 3.02 x 10⁷)/(1.6 x 10⁻¹⁹ x 5.18) = 0.33 m

In multi-beam interference, the interference fringes become sharper due to the constructive and destructive interference of light waves. Multi-beam interference can increase the sharpness of bright fringes by allowing the interference patterns of multiple beams to overlap, creating a more defined and intricate pattern.

In this type of interference, light waves coming from different sources interfere with each other. This results in the formation of fringes of maximum and minimum light intensity known as interference fringes. Multi-beam interference increases the sharpness of bright fringes due to the addition of multiple waves with a specific phase relation.

When the beams of light from multiple sources intersect, the crests and troughs of the waves merge, causing bright fringes to become more pronounced. The sharpness of bright fringes is determined by the angle of incidence and the number of beams that interfere with each other. When the number of beams increases, the sharpness of the fringes also increases.

Therefore, multi-beam interference is essential in many scientific fields where the resolution of bright fringes is important. For instance, in optical metrology, multi-beam interference is used to measure the thickness of thin films and to study the surface quality of materials.

In conclusion, multi-beam interference increases the sharpness of bright fringes by overlapping interference patterns of multiple beams and creating more defined and intricate patterns.

The electric potential at the origin is approximately -5.9 V. So, the correct answer is  -5.9 V.

To calculate the electric potential at the origin, we need to consider the contributions from both charges. The electric potential at a point due to a single point charge is given by the formula:

V = k * q / r

Where V is the electric potential, k is the electrostatic constant (9.0 x 10^9 N·m^2/C^2), q is the charge, and r is the distance from the charge to the point of interest.

Let's calculate the electric potential due to each charge separately:

For charge q1 = 3.5 nC at x = 2.5 m:

r1 = distance from q1 to the origin = 2.5 m

V1 = k * q1 / r1 = (9.0 x 10^9 N·m^2/C^2) * (3.5 x 10^-9 C) / (2.5 m)

For charge q2 = -1.5 nC at x = -2.0 m:

r2 = distance from q2 to the origin = 2.0 m

V2 = k * q2 / r2 = (9.0 x 10^9 N·m^2/C^2) * (-1.5 x 10^-9 C) / (2.0 m)

Now, we can calculate the total electric potential at the origin by adding the contributions from both charges:

V_total = V1 + V2

Substituting the values:

V_total = [(9.0 x 10^9 N·m^2/C^2) * (3.5 x 10^-9 C) / (2.5 m)] + [(9.0 x 10^9 N·m^2/C^2) * (-1.5 x 10^-9 C) / (2.0 m)]

Evaluating this expression, we find:

V_total ≈ -5.9 V
