In music, two notes are said to be an octave apart when one note is exactly twice the frequency of the other. Suppose you have a guitar string playing frequency f0.To increase the frequency by 3 octav
A solid disk of mass M and radius R is pivoted so that it can rotate about its center. The disk is initially at rest. A ball of mass m and speed v travels along a path tangential to the rim of the dis
