A34.0 %-efficient electric power plant produces 800 mw of electric power and discharges waste heat into 20∘c ocean water. suppose the waste heat could be used to heat homes during the winter instead of being discharged into the ocean. a typical american house requires an average 20kw for heating.

how many homes could be heated with the waste heat of this onepower plant?

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire
