Energy is the one that is stored in the ball when it drops. Just before it hits the ground, the energy depends on the mass of the ball and its velocity. When the ball hits, it is compressed and the energy is stored in the compression of the air in the ball and the elasticity of the material that the ball is made from. Some is also converted to heat. The stored energy in the ball causes a force to make the ball back into a round shape and this force presses against the propels and floor the ball back up. The small amount lost as heat is the reason that the ball bounces up with less energy than when it hit.
Answer:
A) or B) which ever you choose in order
Explanation
Hope it helps:)
B. evaporation
c. condensation
They are opposite processes that involve the same transfer of energy
Answer:
B
Explanation:
The process is called Geo-Thermal energy because it's an inexhaustible source of energy
Answer:
orbit the sun have very elliptical orbits
are made of frozen gas and ice
Explanation:
Comets are the made up of dry ice, frozen water, gases and dust particles. it is called dirty snow balls as their nucleus carry frozen water and pieces of rock.
Comets move around the sun in an elliptical orbits and follow Kepler's Laws saying that they move faster when closer to the Sun.
Comets have tails even when they are far from the sun and the tails that point away from the sun.
Hence, the correct options are "orbit the sun have very elliptical orbits and are made of frozen gas and ice".
