An open diving chamber rests on the ocean floor at a water depth of 60 meter. find the air pressure (gage pressure relative to the local atmospheric pressure) in kpa inside of the diving chamber required to keep water from entering the chamber. (assume sg=1.03)

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
