Sometimes thermal energy and sound energy can be harnessed to do useful work. However, these types of energy dissipate rapidly.

Thermal energy produced by friction cannot usually be used to do work.
A) True
B) False

my question is; it says they can be used to do work, but it also says they dissipate rapidly. And the question says "cannot USUALLY". They can, just not all the time. So would that be true? Or false?

    I'd say true because of the words "cannot usually."
