(a) What force is exerted by the atmosphere on a disk-shaped region 2.00 m in radius at the surface of a methane ocean? Answer= 909000 N Please find the answers for B &C t (B ) What is the weight of a 10.0-m deep cylindrical column of methane with radius 2.00 m? Note: The density of liquid methane is 415 kg/m3. (c) Calculate the pressure at a depth of 10.0 m in the methane ocean.James Cameron piloted a submersible craft to the bottom of the Challenger Deep, the deepest point on the ocean’s floor, 11,000 m below the surface. What was the total inward force on the 1.1-m-diameter pilot sphere in which Cameron sat?How much pressure in Pascal does a diver feel 1.0 meters below sea water surface, that is the pressure above atmospheric pressure at that depth? Density of sea water is 1,130 kg/m^3. Gravity is 9.8 m/s^2 Ans

(Use g = 9.8 m/s² for the acceleration due to gravity.) 2m → T 3 m J 4 m Ⓡ 1 m (a) Find the hydrostatic force (in N) on one end of the trough if it is completely full of oil. 35868 XN (b) Compute the force (in N) on one end if the trough is filled to a depth of 1.5 m. (Round your answer to two decimal places.) 17431.85 XN1. Yves is trying to measure the pressure acting on a square platform. He has placed a mass of 30 kg on the disk and he measures the length of one side of the square as 20 cm. What is the pressure Yves should measure? (Hint: To calculate the area of the square platform, first convert the side () to meters and then use the following equation A 12)Hoover Dam is about 180 m high, measured from its low‑water surface to the crest of the dam, and about 380 m long.

- In NCAA softball, the softball is a sphere with a circumference between 11.88 and 12.13 inches [in] and a mass between 177 and 198 grams [g). You find a ball and determine the mass is 180 grams [g] and the specific gravity is 0.32. While this specific gravity seems low for a solid, the ball is not made of a completely solid material but is instead filled with a sponge-like substance. Determine the radius of the ball you found and report the value in units of inches [in]. Click the icon to view the table of common derived units in the SI system. E Click the icon to view the conversion table. The radius is in. (Round your answer to two decimal places.)Consider the flow field produced by a hair dryer. Identify regions of this flow field that can be approximated as irrotational, and those for which the irrotational flow approximation would not be appropriate (rotational flow regions).The circular porthole on a boat is 5 cm in radius and 1.3 m below the surface of a freshwater lake. a) how much pressure does it feel? b) how much force does it feel?
