Question

1. Suppose that a grandfather clock (a simple pendulum) is running slowly; that is, the time it takes to complete each cycle is greater than it should be. You should shorten the pendulum to make the clock keep correct time. True or False?

2. In principle, the motions of a simple pendulum and an object (oscillating) on an ideal spring can both be used to provide the basic time interval or period used in a clock. Which of the two kinds of clocks becomes more inaccurate when carried to the top of a high mountain?

a. Pendulum

b. Oscillating spring

c. Both will be effected.

Answer 1

so shortening the length will decrease the time period that means the clock will run faster.

True

(b) oscillating spring

at the top of the mountain, the pendulum wil loose time du to the gravity.
