Rain falls from clouds for the same reason anything falls to Earth. The Earth's gravity pulls it. But every cloud is made of water droplets or ice crystal(冰晶). Why doesn't rain or snow fall constantly from all clouds? The droplets or ice crystals in clouds are extremely small. The effect of gravity on them is slight. Air currents move and lift droplets …
WebDec 28, 2024 · There is a downward force on it due to gravity of 1 kg × 9.8 m/s 2 = 9.8 N, and an upward force of 5 N. If we use the convention that up is positive, then the net force is 5 N - 9.8 N = -4.8 N, indicating a net force of 4.8 N in the downward direction. WebThen the air pressure from above the book creates a large net downward force of hundreds of pounds. (This will be countered by an upward force from the table.) On the …
WebFrom what I understand, when an elevator accelerates downwards with you, there must be a net force acting downwards on you. Since your true weight remains the same, the net force arises because the elevator exerts a smaller normal force on you which is matched from Newton's Third Law by an equal force downwards on the elevator (this downwards force … WebCorrect options are B) and D) In Fig. (b) A molecule viewed from the top to surface of the fluid.
