When a clock controlled by a pendulum is taken from plains to mountain, it becomes slow but a wrist watch controlled by a spring remains unaffected. Why ?

When a clock controlled by a pendulum is taken from planis to mountain, it becomes slow but a wrist watch controlled by a spring remains unaffected. Why ?

Will a pendulum clock lose or gain time when taken to the top of a mountain?

A pendulum clock and a wrist watch are taken from the earth's surface to a mountain. What will be the effect on their time periods at the mountain ?

A second's pendulum is taken from a place where g=9.8 ms^(-2) to a place where g=9.7 ms^(-2) .How would its length be changed in order that its time period remains unaffected ?

Arrange the following steps of an experiment in a sequential order to determine the frequency of a simple pendulum. (A) Start the stop watch when the bob reaches the extreme position and count the number of oscillations.(B) Suspend a simple pendulum from a cork fixed to a stand. (C) Repeat the experiment and determine the time taken for 20 oscillations. (t_(2)) (D) Pull the bob of the simple pendulum from its initial position of rest and release. (E) Stop the stop watch at the end of 20 oscillations and determine the time taken to complete 20 oscillations (t_(1)) . (F) Determine the average of t_(1) and t_(2) as t. (G) The time period of the oscillation is found using. T = (t)/(20) and frequency using, f = 1/T .
