Calculate the heights of the pendulum

Reference no: EM13687503

Solve the all part of given question:

Question: The coil wand pendulum starts swinging with an angle of 30 degrees with the vertical. After it passes through the magnetic gap, the pendulum rises to a level which makes 10 degrees with the vertical. If the length from the center of mass of the pendulum to the pivot is 30 cm:

Part a: Calculate the heights of the pendulum at the start and final positions.

Part b: What is the energy lost by the pendulum.

Part c: What does the difference in energy loss from 1.716 x 10^-2 J mean.

Part d: If the time for the pendulum takes 0.2 seconds as it passes through the magnetic field, calculate the voltage dropped in the resistor r (see the Figure below). Now the resistances of the coil and the resistors are 1.9 omega and 4.7 omega respectively.

I need expert help for the above question.
