yes
It can be depending on the place and time
Air in the water system.
If they are all dropped at the same time from the same place and there is no air, then the iron block, a piece of tissue paper, a speck of dust, the leaf of a tree, a bird, a truck, and a parachute will all hit the ground at the same time.
Water and air are both fluids. The particles that make them up can 'flow' and move around from place to place
-- If they're dropped in a place where there is air, then that could be accomplished byeither dropping the paper some time before the book, or from a height much lower thanthe height from which the book is dropped.-- If they're dropped in a place where there is noair, then all you have to do is dropthem at the same time from the same height. Without air, they fall together, and reachthe bottom at the same time.
If they're both dropped from the same place at the same time, and fall through a region without air, then they both experience the same acceleration, and hit the ground with the same speed at the same time. If they have to fall through air, water, molasses, etc., then the fluid probably slows the book more than it slows the pencil.
air
No, 200 psi of air is not the same as 200 psi of water. This is because water is denser than air, so the pressure exerted by water at 200 psi would be greater than that of air at the same pressure.
If two objects on the same planet are dropped from the same place at the same time and there is no air resistance, they fall with the same acceleration, and they hit the ground at the same time with the same speed. Their size, mass, weight, temperature, color, political affiliation, race, creed, or sexual orientation make no difference.
Yes, it is true because it works like the way you sneeze. When you sneeze, it transports germs, so air, water, and clothing work the same way with bacteria.
AS WE ALL KNOW THAT water cant stay still for like a minute because the air constantly blow the water and the water move from place to place's harder the air blow the more water moves from another phase.
Yes, the amount of water vapor in the air can vary from place to place due to factors such as temperature, proximity to water bodies, and air currents. Areas with higher temperatures or closer to bodies of water generally have higher amounts of water vapor in the air.
