In the design of a supermarket, there are to be several ramps connecting different parts of the store. customers will have to push grocery carts up the ramps and it is obviously desirable that this not be too difficult. the engineer has done a survey and found that almost no one complains if the force directed up the ramp is no more than 20n. ignoring friction, at what maximum angle theta, should the ramps be built, assuming a full 30-kg grocery cart?

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
