2. A jar of water with a height of 25 cm. Find the absolute pressure at the bottom of the jar, the acceleration due to gravity g = 9.8 m/s? , the density of water is 1000 kg/m and atmospheric pressure = 101 K Pascal.

1. Some species of whales can dive to depths of 800m. What is the total pressure they experience at this depth? (The density of sea water = 1020 kg/m, and 1 ATM =10° N/m)

A submersible vehicle is in a lake at a depth of 29.6 m. What is the absolute pressure (in Pa) at this depth? The density of the water in the lake is 1.00 ✕ 103 kg/m3, and the air above is at a pressure of 101.3 kPa. Pa (b) The submersible vehicle has a circular window with a diameter of 42.0 cm. What force (in N) is exerted by the water on the window of the vehicle at the depth from part (a)? (Enter the magnitude.)       a) Calculate the absolute pressure at the bottom of a fresh-water lake at a depth of 26.6 m. Assume the density of the water is 1.00 ✕ 103 kg/m3 and the air above is at a pressure of 101.3 kPa. Pa (b) What force is exerted by the water on the window of an underwater vehicle at this depth if the window is circular and has a diameter of 29.0 cm?         Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A1 of 10.8 cm2, and the right arm has a cross-sectional area A2 of 5.50 cm2. One hundred grams of water…

A very deep point of the Pacific Ocean is at a depth of 10,100 m below the surface. What is the gauge pressure in the water at that point? The density of seawater is 1025 kg/m3. Ignore the slight variations of g and ρ with depth. Assume g = 9.80m/s2. Assume 3 significant digits.   A. 8.88 ×107 Pa   B. 2.22 ×108 Pa   C. 1.11 ×108 Pa   D. 1.01 x108 Pa   E. 3.33 ×108 Pa   F. 5.55 ×107 Pa
