a magnet of length L is dropped so the front end is at height H from the coil, and you get a graph with two peaks. Each question changes the procedure, and we wish to compare the height of the peaks on new graph to the height of the peaks in the original graph.
suppose the original experiment is done on the Moon, where g, the acceleration due to gravity, is about one-sixth of g on Earth. If the magnet is dropped from height H, how will the graph compare to the original graph?
