Asteam power plant produces 500 mw of electricity with an overall thermal efficiency of 35%. determine (a) the rate at which heat is supplied to the boiler and (b) the waste heat that is rejected by the plant. (c) if the heating value of coal (heat that is released when 1 kg of coal is burned) is 30 mj/kg, determine the rate of consumption of coal in tons(us)/day. assume that 100% of heat released goes to the cycle. (d) what-if scenario: what would the fuel consumption rate be if the thermal efficiency were to increase to 40%?

The great sandini is a 60.0-kg circus performer who is shot from a cannon (actually a spring gun). you don’t find many men of his caliber, so you him design a new gun. this new gun has a very large spring with a very small mass and a force constant of 1100 n/m that he will compress with a force of 4400 n. the inside of the gun barrel is coated with teflon, so the average friction force will be only 40.0 n during the 4.00 m he moves in the barrel. at what speed will he emerge from the end of the barrel, 2.50 m above his initial rest position?
