List two ways to measure the gravitational poterntial energy of a ball when it's dropped from different heights. Think about the motion of the ball and your energy flow diagram, Give an
argument to support your choices. You can include methods that would not work with the
simulation.

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
