Dear physics forum, I am doing an experiment on the vibrational behavior of beams and a question has come up that I can't answer. How does compression affect wave speed? Brief overview of the experiment: studying the change in vibrational behavior of a beam that is gradually tapered...

A nuclear reactor produces 2GW of power, at what rate (grams/sec) is matter converted to energy? Im feeling stumped by this question, I have a feeling it has to do with E-mc^2, but i just don't know where to start, any feedback would be much appreciated, thanks!
