Question

7) A diver descends from a salvage ship to the ocean floor at a depth of 35 meters below the surface. The density of ocean water is 1025 kg/m3.

a. Calculate the gauge pressure on the diver on the ocean floor.




b. Calculate the absolute pressure on the diver on the ocean floor




c. Calculate the tension in the cable if it lifts the plate upward at a slow, constant velocity





d. Will the tension in the hoisting cable increase, decrease, or remain the same if the plate accelerates upward at 0.05 m/s2?

____ Increase ______ Decrease _____ Remain the same

Explain your reasoning.

Please any help???

Explanation / Answer

a) gauge pressure. ?P=D*g*h=3.5e5(Pa). b)P=?P+1e5=4.5e5(Pa). c) what plate. ??? d) i ll increase because we have that T+F_upthurst - mg = a*m. so if a is increased so that T ll increased too.
