A swimmer whose body's surface area is approximately 1.6 m² lies at a depth of 3 m below the water surface. How much force is exerted on his body due to
water pressure.​

What is a possible result of higher air temperature caused by global warming

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)

Which component of the earth’s atmosphere is decreased due to photosynthesis?
