A diver can change his rotational inertia by drawing his arms and legs close to his body in the tuck position. After he leaves the diving board (with some unknown angular velocity), he pulls himself into a ball as closely as possible and makes 2.00 complete rotations in 1.33 s. If his rotational...
An IV is connected to a patient's vein. The blood pressure in the vein has a gauge pressure of 18 mm Hg. At least how far above the vein must the IV bag be hung in order for fluid to flow into the vein? Assume the fluid in the IV has the same density as blood (use 1060 kg/m3 for the density of...
At the surface of a freshwater lake the pressure is 106 kPa. (a) What is the pressure increase in going 35.1 m below the surface? (b) What is the approximate pressure decrease in going 34 m above the surface? Air at 20°C has density of 1.2 kg/m3.
i was almost sure that i needed to use this...

A small block of mass 0.91 kg slides without friction on a horizontal table. Initially it moves in a circle of radius r0 = 0.63 m with a speed 1.5 m/s. It is held in its path by a string that passes through a...
A cylindrical disk has volume 8.99 × 10-3 m3 and mass 8.07 kg. The disk is floating on the surface of some water with its flat surfaces horizontal. The area of each flat surface is 0.633m2. (a) What is the specific gravity of the disk? (b) How far below the water level is its bottom surface? (c)...
