An escalator is used to move 18 people 1.1 minutes from the first floor to the second floor of a department store, 5.3 m above. If the average mass per person is60 kg, how much power (in W) will be needed to move all of these people? Round your answer to the nearest whole number.

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?
