# When a pendulum clock is taken from sea level to the top of a high mountain it will *?

Contents

When the pendulum is taken to the top of mountain, the value of ‘g’ will decrease and hence time period will increase. As the pendulum takes more time to complete one vibration, it will lose time.

## When a pendulum clock is taken to the top of the mountain it becomes slow but a wrist watch controlled by a spring remains unaffected explain why?

When a clock controlled by a pendulum is taken from the plains to a mountain, it becomes slow but a wrist-watch controlled by a spring remains unaffected Due to decrease in the value of g at the mountain, the time period of the pendulum of the clock increases.

## Why does the time period of a pendulum change when taken to the top of a mountain or deep in a mine will a clock keep correct time?

On the top of a mountain, the value of g is less than on the surface of the earth. As T∝1√g , so the time period of pendulum clock increses. It means pendulum clock will take more time to complete one oscillation, i.e., it will be loosing time.

## Will the pendulum lose or gain time when taken to a mountain?

Reason:Value of acceleration due to gravity is less at heights.

## Why does a pendulum clock go slower to mountains?

Answer: The frequency of a pendulum is directly related to the square root of the gravitational constant g. Gravitational force is reduced at high altitude, so the clock runs slower.

## How does the time period get affected if a pendulum clock is taken to higher altitudes give the reason?

Will it gain or lose time? At high altitude, the value of acceleration due to gravity (g) is less than its value on the surface of the earth. So, it will take more time for the pendulum clock to complete one oscillation and hence, it will lose time. …

## What is variation of a time period of a pendulum clock?

The second hand of the clock advances by one second that means second hand moves by two seconds when one oscillation is complete. A pendulum clock keeps proper time at temperature θ₀. If temperature is increased to θ (> θ₀) then due to linear expansion, length of pendulum and hence its time period will increase.

## When a pendulum clock is taken from sea level?

Solution for problem 7Q Chapter 11

Why? The equation for pendulum motion is: As we gain altitude the value of constant of gravity ‘g’ decreases. If a pendulum clock which is accurate at sea level is taken to high altitude it will slow down.

## Why does a pendulum clock gain time when taken from equator to the pole?

we know, acceleration due to gravity, g value at pole is greater than at equator. if it is taken to the poles g value increases. time period decreases so, the pendulum clock gains time. hence, if a pendulum clock gives correct time at the equator then, it gains time if it is taken to the poles.

## How does the period of a simple pendulum change when it is taken to the top of a hill?

When the pendulum is taken to the top of mountain, the value of ‘g’ will decrease and hence time period will increase. As the pendulum takes more time to complete one vibration, it will lose time.

## What is the effect of the pendulum clock when it is taken to the mines?

looses time, length to be decreased.

## What is the effect on time period of simple pendulum when it is taken a inside a deep mine B on a mountain?

The time period. Either sides of surface of earth g goes on decreasing, hence period increases.

## What will happen to the time period of simple pendulum when taken to a moon B Mount Everest C deep inside the Earth?

When we go the moon, the acceleration due to gravity decreases. As acceleration due to gravity is inversely proportional to the time period, the time period shall increase.

## How could a pendulum be used to measure altitude?

In can be used per the following Method of Procedure (MOP) to measure altitude: Immobilize the internal pendulum components, and close and secure the air-tight enclosure. Take the instrument, and a stopwatch, to a location AT the altitude to be measured, from which a clear line of sight to the.

## When air resistance is ignored does a pendulum clock run faster or slower at higher altitude?

At higher altitude gravity becomes weaker so pendulum cannot be restored quickly (gravity acts as a restoring force). Therefore, the pendulum clock will run slower at higher altitude.
