Answer:
Explanation:
Potential energy on the surface of the earth
= - GMm/ R
Potential at height h
= - GMm/ (R+h)
Potential difference
= GMm/ R - GMm/ (R+h)
= GMm ( 1/R - 1/ R+h )
= GMmh / R (R +h)
This will be the energy needed to launch an object from the surface of Earth to a height h above the surface.
Extra energy is needed to get the same object into orbit at height h
= Kinetic energy of the orbiting object at height h
= 1/2 x potential energy at height h
= 1/2 x GMm / ( R + h)
Answer:
derecha, izquierda, derecha, arriba
Explanation:
Matter cannot be created or destroyed under normal conditions. The big rock is weathered by the river water and goes through wear and tear because of its motion, and finally turns into gravel. So the lost part of the rock has been converted to soil .-.
It is known as silicon dioxide or silica!
Hope this helps!
