If atoms lose , they become more organized.
When energy is removed from a given amount of atoms, they enter a more organized state because their attractive forces overcome their repulsive forces, which causes them to come closer. This is observed when a gas is condensed to a liquid, and then also when a liquid freezes into a solid. This moving closer also limits the motion of the particles.
The energy that the student shoud use in order to climb the stairs is equal to its increase in gravitational potential energy:
![W= \Delta U= mg \Delta h](https://tex.z-dn.net/?f=W%3D%20%5CDelta%20U%3D%20mg%20%5CDelta%20h)
where m is the mass of the student, g the gravitational acceleration and
![\Delta h](https://tex.z-dn.net/?f=%5CDelta%20h)
the variation of height. Plugging numbers into the equation, we find
![W=(60 kg)(9.81 m/s^2)(40 m)=23544 J](https://tex.z-dn.net/?f=W%3D%2860%20kg%29%289.81%20m%2Fs%5E2%29%2840%20m%29%3D23544%20J)
The power required for the student to climb the stairs is equal to the work done divided by the time taken:
The answer is <span> A. Yes, the wave will transfer the energy of Amy's motion to the other end of the rope.</span>
Answer:
option c
Explanation:
The temperature must be constant. Ohms law states that the current running through a conductor is directly proportional to the potential difference across it provided the temperature remains constant
