A certain coal-fired power plant has a rated power capacity of P = 950 MW. The output of this plant is W = 0.25QH, where QH is the energy input as heat from the hot reservoir. a)Calculate the absolute value of the exhausted heat (QC) each second in MJ for the power plant. b)If the power plant operates for a full day at its rated capacity, how much energy QH in MJ is needed? c)If, on average, one ton of coal contains Q = 25 GJ of energy, how many tons nH of coal would the plant need to operate for a day at its rated capacity?
