During a single work-shift of 8h, a factory consumes 4.5×103MJ of electrical energy.
(i) Express this energy in kilowatt-hour.
(ii) Determine the average electrical power drawn by the factory in kilowatts.
(iii) Convert the power obtained in part (ii) into watts and hence state how many joules of energy the factory uses each second.
