Question

Can Someone show me how to graph and solve number 3.  

Also, number 1 and 2 as well. I solved number 1, but I just want tp double check on my answer.

Suppose a student recorded the following data during Step 10 of this experiment, The student was careful to start taking data when the angular position of the pendulum was zero. Unfortunately he docs not have a computer available to fit the data as we did in Step 12, but he knows that the amplitude of oscillations decays exponentially according to A = A0 e-(Bt) + C. Use the data obtained by the student to plot a straight line graph of the appropriate variables, and use it to find values for the parameters A0 and R. The circular coil at the end of the pendulum has 200 turns and a diameter of 1.9 cm. When the magnets are separated by about 1.0 cm the field between them is 0.50 T. Use this information and the graph obtained in Step 3 to calculate the induced emf when the pendulum entered the magnetic field region. Explain why the oscillations decay faster when there is no load connected to the coil.

Explanation / Answer

For number 1! Magnetic field = 0.234 and Ao = 8.3 ( depends on the A and t you use ).
