please show steps
The mechanical power output of an electric motor is 3.0 hp. The motor is connected to a 120 V source and is 85% efficient in converting power that it takes in by electrical transmission into mechanical power. Determine the following. (a) current (in A) delivered to the motor energy (in MJ) delivered to the motor by electrical transmission in 5.0 hours of operation the cost to run the motor (in dollars) for 5.0 hours, if the electric company charges $0.12/kWh. (b) (c)
