Solar energy and Geothermal energy are your answers :)
Answer:
Work done.
Explanation:
The skater who lifts has to overcome the partner's weight. When lifted up by 1 meter, her potential energy increases by (mass)x(gravitational acceleration)x(1meter), which is the amount of work done.
(This all assumes lifting vertically and no other forces being part of the picture)
An impact which stops a moving object must do enough work to take away its kinetic energy, so extending the distance moved during the collision reduces the impact force.
<span>No, xenon wont react with nitrogen.
This is because xenon is a noble gas and noble gases on</span>ly react with other elements under very unusual circumstances.<span>
