An ideal heat engine operates between 778 K and 475 K. 267 J of waste heat is exhausted. What is the input heat?

Explanation:

Suppose that the turbines of a coal-fired plant are driven by hot gases at a temperature of 886 K. the temperature of the exhaust area is only 305 K,  the efficiency of this heat 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.)

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
