What causes air to move towards the water from the land during the night? The ground cools faster at night than the water, which retains its heat, warming the air above it.

The ground retains the heat from the Sun longer than the water.

Gravity moves the air towards the water because water is lower than the land.

The dry air over the land is heavier than the air over the water that contains more water vapor.

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
