Determining gage pressure and ratio of absolute pressure at a particular depth of fresh water.

1. Some skin divers go as deep as 50 m. What is the gage pressure at this depth in fresh water, and what is the ratio of absolute pressure at this depth to normal atmospheric pressure? Suppose T = 20°C.

2. Find the force of the gate on the block.
