- Is this correct? If so, explain. Thank u?Suppose an Olympic diver who weighs 52.0 kg executes astraight dive from a 10-m platform. At the apex of the dive,the diver is 10.8 m above the surface of the water. (a) Whatis the potential energy of the diver at the apex of the dive,relative to the surface of the water? (b) Assuming that all thepotential energy of the diver is converted into kinetic energyat the surface of the water, at what speed, in m/s, will thediver enter the water? (c) Does the diver do work on enteringthe water? Explain.Given the following values what is the boiling point of unknown compound D2 in °C?
