Answer:
P = 360 Watts
Explanation:
Given that,
The weight of a student, 
It takes 15 seconds to run up a hill.
The top of the hill is 10 meters vertically above her starting point.
We need to find the power develop during her run. We know that te power developed is given by :
So, the power develop during her run is 360 W.
<span>The windchill index tells you A. how wind and temperature affect your body in winter. This is how you perceive the temperature outside due to the flow of air. The windchill index is always lower than the measured temperature outside. This is because wind increases the rate at which your body loses heat. For example, if it is 25 degrees outside, but there is a strong wind, the perceived temperature on your skin may be closer to 15 degrees.</span>
The magnetic north pole of the earth's magnet is in the geographic south pole.
- There are two magnetic and geographic poles each, north and south
- The two geographic poles are the locations where the earth's axis of rotation passes through which is imaginary
- The magnetic north and south poles are not the same as the geographic north and south poles
- In a compass, the needle points to the magnetic north pole
- By convention, the magnetic north pole corresponds to the geographic south pole
- The magnetic south pole corresponds to the geographic north pole
- The magnetic field lines of a magnet start from the magnetic north pole and end at the magnetic south pole
The magnetic north pole of the earth's magnet is the geographic south pole.

Torque = (force) x (distance from the pivot) = (10 n) x (0.9 m) = 9 newton-meters
Answer:
If force is applied to cause the motion of the body
Explanation:
In the setup given in this diagram, potential energy can be converted into kinetic energy by applying force on the cart or object to move it down the slope.
Potential energy is the energy due to the position of a body. The body has huge potential energy at its current position.
Kinetic energy is the energy due to the motion of a body.
As the body moves down the slope and its velocity increases, it gains massive kinetic energy.
Down the slope, the kinetic energy increases as the potential energy decreases.
At the bottom of the slope, the potential energy becomes zero and the kinetic energy is at its maximum.
