The mechanical power output of an electric motor is 3.40 hp. The motor is connected to a 120 V source and is 94.0% 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 [Input Box] A(b) Energy (in MJ) delivered to the motor by electrical transmission in 3.70 h of operation [Input Box] MJ(c) The cost to run the motor (in dollars) for 3.70 h, if the electric company charges $0.110/kWh [Input Box] $

Given values, Mechanical power output, Pm=3.40 hp=3.40×745.7=2535.38 Watt=2.54 KW Voltage source,…
