Measured along the surface of the water, a rectangular swimming pool has a length of 17 m. Along this length, the flat bottom of the pool slopes downward at an angle of 12 ° below the horizontal, from one end to the other. By how much does the pressure at the bottom of the deep end exceed the pressure at the bottom of the shallow end?

A rectangular swimming pool is 8 m ✕ 34 m in area. The depth varies uniformly from 1 m in the shallow to 3 m in the deep end. (a) Determine the pressure at the deep end of the pool and at the shallow end. (b) What is the net force on the bottom of the pool due to the water in the pool? (Ignore the effects of the air above the pool for this part.)

A boy stands on a diving board and tosses a stone into a swimming pool. The stone is thrown from a height of 2.50 m above the water surface with a velocity of 4.00 m/s at an angle of 60.0° above the horizontal. As the stone strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the stone enters the water,...

A laser is aimed at the top of a pool of water. The beam makes an angle of 32 degrees to the normal to the water's surface. If the pool of water is 2.3 m deep with a flat bottom, where will the light beam hit the bottom of the pool relative to its entrance point on the air–water interface. Use nair = 1 and nwater = 1.33 for your calculations.

Taylor enjoys swimming in the pool. At 3 m below the surface, she blows some bubbles of air. As these bubbles rise up toward the surface of the pool, what happens to their size? Assume that its temperature remains constant. (Hint: an air bubble underwater has the same pressure as that of the surrounding water.) the bubbles get bigger. the bubble size may increase or decrease depending on the rate they rise. the bubble size remains constant. the bubbles get...

(v) Two bricks of identical volume are sitting at the bottom of a swimming pool where the water depth is constant. Brick 1 has a density twice that of Brick 2. Which of the following is true in relation to the buoyancy forces on the bricks? (a) The buoyancy force is the same on both bricks. (b) The buoyancy force is twice as large on Brick 1 than on Brick 2. (c) The buoyancy forces are zero because the bricks...

A swimming pool appears to be 3.30 m deep when looking at an angle of incidence of 25 degrees, how deep is it really? n = 1.33   My professor provided this as the answer: "Use the approximation that the x distance doesn't appear to change, just the y depth. This isn't completely true, but is a good approximation. That means our eyes believe the light doesn't bend. So we think the triangle below the surface still is at an angle...
