A simple pendulum with a period of 2 seconds can be used as a chronograph to measure time with great accuracy. A platinum wire attached to the bob completes the electric timing circuit through a drop of mercury as it swings though the lowest point. a. What should be the length, L, of the pendulum

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
