F=ma, so a=F/m. Thus, the more massive object accelerates more slowly, that is, the 21 kg object is three times slower than the 7 kg one (2nd variant, 7kg is 3 times faster than 21kg)
Answer:
Convection cells
Explanation:
As the cold air moves away from poles, it begins to warm up. This warm air now becomes lighter and the pressure drops significantly at 60° N and 60° south latitude. The air from poles further gushes into these belts because the low pressure created. Thus, convection cells are formed because this rise and fall of air in circular pattern.
Hence, the name given is convection cells.
Answer:
Yes, I think

Explanation:
The gas giants have atmospheres that are mostly hydrogen and helium. All four planets rotate relatively rapidly – while Earth spins once on its axis every 24 hours, Saturn spins once every 10 hours. Like Earth, all the gas giants have wind bands. These are seen as east-west stripes.
The crust and the upper mantle.
