In order to attain orbit around earth, the ATLAS-V rocket must accelerate up to a speed of about 7700m/s in about 11 minutes.
a) What average acceleration is required to accomplish this?
b) If the mass of the rocket + fuel is 3.05x105 kg, what is the applied force of the engine?

For waves in the ocean, the medium of the waves is a. air b. water c. energy d. a passing boat

Arigid tank is divided into two equal parts by a partition. one part of the tank contains 3 kg of compressed liquid water at 400 kpa and 60°c while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. determine the entropy change of water during this process, if the final pressure in the tank is 40 kpa. use steam tables.

Energy transformations that involve one transformation from one type of energy to another are called transformations.
