A 120-V motor has mechanical power output of 2.20 hp. It is 91.0% efficient in converting power that it takes in by electrical transmission into mechanical power. (a) Find the current in the motor. A (b) Find the energy delivered to the motor by electrical transmission in 2.50 h of operation. MJ (c) If the electric company charges $0.110/kWh, what does it cost to run the motor for 2.50 h

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
