A heat engine takes in 370 J of energy from a hot reservoir and performs 26.0 J of work in each cycle.(a) Find the efficiency of the engine.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

the inner core.

good luck: )
