1. At the bottom of the pool the water pressure is greater than the pressure at the top of the pool (True,False)
2. The atmospheric pressure at the sea level is greater than the atmospheric pressure at the mountain top (True,False)
3. A cake of soap placed in a bathtub of water sinks. The buoyant force on the soap is less than the weight of the soap (True,False)
Homework Answers
1) True because the pressure in a liquid increases as you go deep inside the liquid as the pressure liquid exerts increases as you go deep inside
2) False as you go above the air pressure is decreased and is lesser than atmospheric pressure at sea level as density of air decreases as you reach top
