Answer:
1111 m
Explanation:
The following data were obtained from the question:
Height (h) = 500 m
Horizontal velocity (u) = 110 m/s
Horizontal distance (s) =?
Next we shall determine the time taken for the pallet to get to the target. This can be obtained as follow:
Height (h) = 500 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =?
h = ½gt²
500 = ½ × 9.8 × t²
500 = 4.9 × t²
Divide both side by 4.9
t² = 500/4.9
Take the square root of both side.
t = √(500/4.9)
t = 10.1 s
Finally, we shall determine how far the pallet needs to be dropped in order to get to the target. This can be obtained as follow:
Horizontal velocity (u) = 110 m/s
Time (t) = 10.1 s
Horizontal distance (s) =?
s = ut
s = 110 × 10.1
s = 1111 m
Thus, the pallet must be dropped at a distance of 1111 m from the plane in order to get the target.

How much kinetic energy does a 2 kg book falling out of the backpack with a velocity of 4 m/s have?
Answer:
E = 16 J
Explanation:
Given that,
Mass of a book, m = 2 kg
Velocity of the book from the backpack, v = 4 m/s
We need to find the kinetic energy of the book falling out of the backpack. Due to the motion of the object, kinetic energy is possessed by it. It can be given by :
[tex]E=\dfrac{1}{2}mv^2\\\\=\dfrac{1}{2}\times 2\ kg\times (4\ m/s)^2\\\\=16\ J[/tex]
So, the kinetic energy of the book is 16 J.
Two particles A and B move at a constant speed in circular paths at the same angular speed ω. Particle A's circle has a radius that is the length of particle B's circle. What is the ratio vA/vB of their translational speeds?
Answer:
2:1
Explanation:
It is given that,
Two particles A and B move at a constant speed in circular paths at the same angular speed ω.
Particle A's circle has a radius that is the length of particle B's circle.
We need to find the ratio of vA/vB of their translational speeds.
As the angular speed is same. The relation between angular and linear speed is given by :
[tex]\omega=\dfrac{v}{r}\\\\\omega_A=\omgega_B\\\\\dfrac{v_A}{r_A}=\dfrac{v_B}{r_B}[/tex]
As [tex]r_A=2r_B[/tex]
So,
[tex]\dfrac{v_A}{2r_B}=\dfrac{v_B}{r_B}[/tex]
[tex]\dfrac{v_A}{v_B}=2[/tex]
So, the ratio of their translational speeds is 2:1.

Cual es la aceleracion en metros por segundo al cuadrado de un carro que cambia de velocidad de noventa kilometros por hora a veinte metros por segundo al cuadrado en seis segundos
Answer:
El carro decelera a una tasa de 0.833 metros por segundo cuadrado.
Explanation:
Inicialmente, convertimos la velocidad inicial del carro a metros por segundo:
[tex]v_{o} = 90\,\frac{km}{h}\times \frac{1}{3600}\,\frac{h}{s}\times 1000\,\frac{m}{km}[/tex]
[tex]v_{o} = 25\,\frac{m}{s}[/tex]
Si asumimos que el carro decelera de manera uniforme, entonces empleamos la siguiente ecuación cinemática para determinar la aceleración ([tex]a[/tex]), medida en metros por segundo al cuadrado:
[tex]a = \frac{v-v_{o}}{t}[/tex] (1)
Donde:
[tex]v_{o}[/tex], [tex]v[/tex] - Velocidades inicial y final, medidas en metros por segundo.
[tex]t[/tex] - Tiempo, medido en segundos.
Si sabemos que [tex]v_{o} = 25\,\frac{m}{s}[/tex], [tex]v = 20\,\frac{m}{s}[/tex] y [tex]t = 6\,s[/tex], entonces la deceleración del carro es:
[tex]a = \frac{20\,\frac{m}{s}-25\,\frac{m}{s} }{6\,s}[/tex]
[tex]a = -0.833\,\frac{m}{s^{2}}[/tex]
El carro decelera a una tasa de 0.833 metros por segundo cuadrado.
Thirty-five (35.0) mL of ozone (O3) is stored at a temperature of 285 K and a pressure of 150.0 Pa. If the pressure is decreased to 125 Pa, what will be the new temperature?
Answer:
Temperature T2 = 237.5 K
Explanation:
Given:
Volume = 35 ml
T1 = 285 k
P1 = 150 pa
P2 = 125 pa
Find:
Temperature T2
Computation:
P1V/T1 = P2V/T2
150(35) / 285 = 125(35) / T2
Temperature T2 = 237.5 K
An object with an initial speed of 4.0 meters per second accelerates uniformly at 2.0 meters per second squared in the direction of its motion for a distance fof 5 meters. What is the final speed of the object
Answer:
6 m/s.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 4 m/s
Acceleration (a) = 2 m/s²
Distance (s) = 5 m
Final velocity (v) =?
The final velocity of the object can obtained as shown below:
v² = u² + 2as
v² = 4² + (2 × 2 × 5)
v² = 16 + 20
v² = 36
Take the square root of both side.
v = √36
v = 6 m/s
Therefore, the final speed of the object is 6 m/s.
The final speed of the object as it accelerates uniformly in the direction of its motion is 6m/s.
Given the data in the question;
Initial speed; [tex]u = 4.0m/s[/tex]Acceleration; [tex]a = 2.0m/s^2[/tex]Distance; [tex]s = 5m[/tex]Final speed; [tex]v = \ ?[/tex]
To determine the final speed of the object, we use the third equation of motion:
[tex]v^2 = u^2 + 2as[/tex]
Where v is the final speed or velocity, u is the initial velocity, a is the acceleration and s is the distance covered.
We substitute our given values into the equation
[tex]v^2 = [(4.0m/s)^2] + [ 2\ *\ 2.0m/s^2\ *\ 5m ]\\\\v^2 = 16m^2/s^2 + 20m^2/s^2\\\\v^2 = 36m^2/s^2\\\\v = \sqrt{36m^2/s^2} \\\\v = 6m/s[/tex]
Therefore, the final speed of the object as it accelerates uniformly in the direction of its motion is 6m/s.

If you have two wires made out of the same material and the same thickness, one is 3-inches long and one is 6-inches long, which one has the greater resistance?
plz help!!
Answer:
The 3-inch wire has greater resistance.
Explanation:
The only difference between the wires is their length. According to the formula for resistance, the longer wire will have greater resistance.
What is Ohm's law?Ohm's law is a fundamental law of electrical circuits that describes the relationship between voltage, current, and resistance in a conductor. It states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. This law is named after Georg Simon Ohm, a German physicist who first stated it in 1827.
The mathematical equation for Ohm's law is:
V = IR
Where:
V is the voltage or potential difference measured in volts (V)
I is the current flowing through the conductor measured in amperes (A)
R is the resistance of the conductor measured in ohms (Ω)
This equation states that the voltage (V) applied across a conductor is equal to the product of the current (I) flowing through the conductor and the resistance (R) of the conductor.
In other words, Ohm's law tells us that if we increase the voltage applied to a conductor, the current flowing through it will also increase, assuming the resistance stays constant. Similarly, if we increase the resistance of a conductor, the current flowing through it will decrease, assuming the voltage stays constant.
Ohm's law is an essential concept in electrical engineering and is used extensively in the design and analysis of electrical circuits. It allows us to predict how changing the voltage, current, or resistance in a circuit will affect the other two variables.
Here in the question,
Assuming that the wires have the same cross-sectional area and are made of the same material, the longer wire will have greater resistance. This is because the resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area.
The resistance of a wire can be calculated using Ohm's law: R = V/I, where R is resistance, V is voltage, and I is current. The resistance can also be calculated using the formula: R = ρL/A, where ρ is the resistivity of the material, L is the length of the wire, and A is the cross-sectional area of the wire.
Since the wires are made of the same material and have the same thickness, their cross-sectional areas will be the same.
Therefore, the only difference between the wires is their length. According to the formula for resistance, the longer wire will have greater resistance.

Answer:5250 N
Explanation: ig:iihoop.vince
The force of friction between the car's tires and the road is 5250 N
Centripetal force is the force that is perpendicular to an object moving in circular motion. It is given by:
F = mv²/r
where m is the mass of object, v is the velocity and r is the radius of circle.
Given that m = 700 kg, v = 30 m/s, r = 120 m, hence:
F = mv²/r = 700 * 30²/120 = 5250 N

Explanation:
1. If a worker has come into contact with electricity the worker may not be able to remove themselves from the electrical source. The human body is a good conductor of electricity. If you touch a person while they are in contact with the electrical source, the electricity will flow through your body causing electrical shock. Firstly attempt to turn off the source of the electricity (disconnect). If the electrical source can not readily and safely be turned off, use a non-conducting object, such as a fibreglass object or a wooden pole, to remove the person from the electrical source.

Question 2 How can an induced magnet be made stronger? adding more secondary coils O adding more induction O adding more primary coils
Answer: adding a secondary coils
Explanation:
You can make an electromagnet stronger by doing these things: wrapping the coil around a piece of iron (such as an iron nail) adding more turns to the coil. increasing the current flowing through the coil.
Induced magnet be made stronger,by adding more secondary coils.
Increasing the magnetic field applied to the magnetizable material in turn makes its own magnetic field stronger. Similarly, wrapping with thicker wire has the same effect, but by increasing the current. Like a widening river, a thicker conductor allows more current through.
What is secondary coil ?"Coil such that current is induced in it by passing a current through the primary coil. secondary winding, secondary. coil - reactor consisting of a spiral of insulated wire that introduces inductance into a circuit."
