The U-tube in Fig.  is moving to the right with variablevelocity. The water level in the left tube is 6 cm, andthe level in the right tube is 16 cm. Determine the accelerationand its direction.

Consider a large cubie ice bloek floating in seawater. The specific gravities of ice and water are 0.92 and 1.02, respectively. If a 10 cm high portion of the ice block extends above the surface of the water as shown in figure below, determine the height of the ice block below the surface, (Ans: 87.6 cm)

Water stands ata depth H in a large, open tankwhose side walls are vertical. A hole is madein one of the walls at a depth hbelow the water surface. (a) Atwhat distance R from the footof the wall does the emergingstream strike the floor? (b) Howfar above the bottom of the tankcould a second hole be cut so that the stream emerging from it couldhave the same range as for the first hole?

Two hemispherical shells of negligible mass and radius R = 1.2 m are put together alongtheir horizontal rim, then the (now complete) sphere is submerged in water. The lower hemisphereis tied to the bottom of the water tank, and this way the center of the sphere is located at depthH = 10 m. Inside the sphere there is air of pressure p0 = 105 Pa (which is the same as theatmospheric pressure). Find the force exerted by the lower hemisphere on the upper hemisphere.

What force is needed to pull one microscope slide overanother at a speed of 1.00 cm/s, if there is a 0.500-mm-thicklayer of 20º C water between them and the contact area is8.00 cm2 ?
