A thin rod of length L is fixed on a ceiling so that it can freely oscillate. Find its equation of motion and the period of oscillation

Answer sample (c); // would be best because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest;

When seismic waves hit a fault, the waves are reflected off the fault. seismograph can detect these reflected seismic waves. geologists then use these data to map the fault's length and depth

The object's initial distance above the groundthe object's initial velocity
