An escalator carries you from one level to the next in an airport terminal. The upper level is 4.6 m above the lower level, and the length of the escalator is 7.4 m . Assume that your mass is 64 kg . How much work does the up escalator do on you when you ride it from the lower level to the upper level?
How much work does the down escalator do on you when you ride it from the upper level to the lower level?

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop
