An electrical short cuts off all power to a submersible diving vehicle when it is a distance of 29 m below the surface of the ocean. The crew must push out a hatch of area 0.950 m2 and weight 390 N to escape.

If the pressure inside is 1.0atm, what downward force must they exert on the hatch to open it?

For which pair of objects would adding the same a

In which of the following would the particles move most rapidly? a. ice at -20 °c b. water at 20 °c c. steam at 110 °c d. boiling water e. ice at 0 °c

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
