Homework Answers
1] option a is correct, Period will be same,
Period is given by T = 2pi*sqrt(m/k)
2] In this case, both period as well as amplitude will be same,
option C is correct,
3] Time taken will be half of the time period of the pendulum
t =0.5T = 0.5* [2pi*sqrt(l/g)]= pi*sqrt(25/9.8) = 5 s
option A is correct
4] option c is correct,
Time period of a pendulum is independent of mass.

Pendulum Clocks Are Very Important...
1. Pendulum clocks are very important for the history of exploration. Accurate time was the best way to determine one's longitude, since the time of sunrise or sunset depends sensitively on your longitude. In this regard, the great enemy of accuracy was thermal expansion of the pendulum used for the chronometer. We are considering a large mass attached at the end of a brass rod. The mass at the end is much greater than the mass of the rod, so we...

part A.) A producer wants to move a bridge prop with oscillating springs to another planet, hoping that it will make the oscillations change their period and thereby signifying to viewers there is a change in location. What do you tell him? -answer choices a.) The periods of the spring oscillations would not change appreciably unless the gravity on the planet were twice as large or twice as small as that on earth. b.) The periods of the spring oscillations...

A pendulum has a length 1 m and a mass 1 kg. Assume Earth free fall acceleration equal to 10 m/s^2. When the pendulum oscillates, the maximal deflection angle is +/- 1 degree. a) Sketch the kinetic energy as a function of time between t =0 and t = 10. b) Sketch the total energy = kinetic energy + potential energy between t=0 and t = 10. c) Suppose the pendulum started losing energy at the rate 1% per period....

1. An auto CD rotates at 480 rpm (rev/min). What is the period and frequency of the CD? 2. In physics class, your teacher shows you a demonstration of a spring � mass system. A spring is connected to a cart on an air track. She moves the cart 0.15 m from its equilibrium position and lets go at t = 0. The cart completes 1 oscillation every 3.0 seconds. What is the position of the cart at 0.30 seconds?...
