A 120-V motor has mechanical power output of 2.60 hp. It is 85.0% efficient in converting power that it takes in by electrical transmission into mechanical power.
(a) Find the energy delivered to the motor by electrical transmission in 3.20 h of operation.
(b) If the electric company charges $0.110/kWh, what does it cost to run the motor for 3.20 h?
A basketball star covers 2.6 m horizontally in a jump to dunk the ball. His motion through space can be modelled precisely as that of a particle at his center of mass. His center of mass is at elevation 1.02m when he leaves the floor. It reaches a..
A 20-cm-radius ball is uniformly charge to 80nC. What is the ball's volume charge density and How much charge is enclosed by spheres of radii 5, 10 and 20 cm
To measure the static friction coefficient between a 4.78-kg block and a vertical wall, the setup shown in the drawing is used. what is the coefficient of static friction
A 3500 kg block falls vertically through 5 m and then collides with a 400 kg pile, driving it 3.0 cm into bedrock. Assuming that the block-pile collision is completely inelastic, find out the magnitude of the average force on the pile from the bed..
A model train moves along a horizontal circular track with a radius of 0.5 m. Starting from rest, What is the angular acceleration (in rad/s2) of the train
