A very light rigid rod with a length of 0.692 m extends straight out from one end of a meter stick. The combination is suspended from a pivot at the upper end of the rod as shown in the following figure. The combination is then pulled out by a small angle and released.
(a) Determine the period of oscillation of the system.
(b) By what percentage does the period differ from the period of a simple pendulum 1.192 m long?
An accurate clock is kept in a laboratory located on the equator of the Earth, calculate the difference that accumulates between the laboratory clock and each of the two flying clocks upon one trip around the Earth
Two equally charged particles, held 22.4 cm apart, are released from rest. The initial acceleration of the first particle is observed to be 4.0 m/s2 and that of the second particle is 6.0 m/s2. If the mass of the first particle is 3.40 x 10-7 kg, ..
