# A diver descends from a salvage ship to the ocean floor at a depth of \(35 \text{ m}\) below the surface. The density of ocean water is \(1.025 \times 10^3 \text{ kg/m}^3\). Calculate the gauge pressure on the diver on the ocean floor. Calculate the absolute pressure on the diver on the ocean floor. The diver finds a rectangular aluminum plate having dimensions \(1.0 \text{ m} \times 2.0 \text{ m} \times 0.03 \text{ m}\). A hoisting cable is lowered from the ship and the diver connects it to the plate. The density of aluminum is \(2.7 \times 10^3 \text{ kg/m}^3\). Ignore the effects of viscosity.

A diver descends from a salvage ship to the ocean floor at a depth of \(35 \text{ m}\) below the surface. The density of ocean water is \(1.025 \times 10^3 \text{ kg/m}^3\).

**Part a)** Calculate the gauge pressure on the diver on the ocean floor. *(3 points)*

**Part b)** Calculate the absolute pressure on the diver on the ocean floor. *(3 points)*

**Part c)** The diver finds a rectangular aluminum plate having dimensions \(1.0 \text{ m} \times 2.0 \text{ m} \times 0.03 \text{ m}\). A hoisting cable is lowered from the ship and the diver connects it to the plate. The density of aluminum is \(2.7 \times 10^3 \text{ kg/m}^3\). Ignore the effects of viscosity. Calculate the tension in the cable if it lifts the plate upward at a slow, constant velocity. *(3 points)*

**Part d)** Will the tension in the hoisting cable increase, decrease, or remain the same if the plate accelerates upward at \(0.05 \text{ m/s}^2\)? Explain your reasoning. *(3 points)*
