1. A Ping-Pong ball has a diameter of 3.8 cm and average density of 0.084 g/cm3. What force is required to hold it completely submerged under water?

2. A tank with a cover, containing a liquid of density p, has a hole in its side at the distance y1 from the bottom. The diameter of the hole is small relatively to the diameter of the tank. The air above the liquid is maintained at a pressure P. Assume steady frictionless flow and show that the speed at which the fluid leaves the hole when the liquid is a distance h above the whole is.... (see attachment for remainder of the questions).

This solution is provided in 869 words in an attached file. Bernouille's equation is used to determine velocity, and multiple diagrams are used for the problems to further understanding of the solution, along with step-by-step equations.
