A bubble having a diameter of 82 cm is re- leased from a depth of 5.1 m from the bottom of a swimming pool. The temperature of the water at the surface is 20◦C, whereas it is 15◦C at the bottom. What will the diameter of the bubble be when it reaches the surface? The acceleration of gravity is 9.8 m/s2 and the density of water is 1000 kg/m3. Answer in units of cm.

A closed and elevated vertical cylindrical tank with diameter 80 cm contains water to a depth of 0.900 m . A worker opens a circular hole with diameter 12 cm in the bottom of the tank. As the water drains from the tank, compressed air above the water in the tank maintains a gauge pressure of 5.00×103Pa at the surface of the water. Ignore any effects of viscosity ( ½w = 1000 kg=m3 ). a) (12 points) Just after the...

A child playing in a swimming pool realizes that it is easy to push a small inflated ball under the surface of the water whereas a large ball requires a lot of force. The child happens to have a styrofoam ball (the shape of the ball will not distort when it is forced under the surface), which he forces under the surface of the water. If the child needs to supply 608 N608 N to totally submerge the ball, calculate...

A vertical dam has a semicircular gate as shown in the figure. The total depth d of the figure is 42 m, the height h of air above the water level is 6 m, and the width w of the gate is 8 m. Find the hydrostatic force against the gate. (Round your answer to the nearest whole number. Use 9.8 m/s2 for the acceleration due to gravity. Recall that the weight density of water is 1000 kg/m3.)

A uniform, wooden cube with length d = 3.0 cm on each side has a density r = 500 kg/m3 and floats motionlessly in water (density 1000 kg/m3). (Take the acceleration due to gravity to be 9.8 m/s2.) When pressed down by a small amount, and released, what is the approximate frequency of the resulting up-and-down oscillations?
