Anuclear power plant operates at 68 % of its maximum theoretical (carnot) efficiency between temperatures of 680 ∘c and 400 ∘c. part a if the plant produces electric energy at the rate of 1.5 gw , how much exhaust heat is discharged per hour? express your answer using two significant figures.

What is required for an electric charge to flow through a wire? zero resistance in the wire a balance of electric potential high resistance in the wire a difference in electric potential

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
