Question

Give the drawbacks to use the period of a pendulum as a time standard?
Not from google please!

Answer 1

Answer:

Drawbacks to use time period of a pendulum as a time standard

Air friction can change the time period.

Due to increase in temp length of pendulum

Increase and hence the time period increases.

Due to change in position from sea level gravitational acceleration changes hence time period changes.

hope this will it is from q1 STD book

Answer 2

Answer:

The drawbacks are: Change in time period due to air friction.

Length of pendulum affected due to temperature increase.

Explanation:

The drawbacks of using the period of a pendulum as a time standard is as below:

1. Change in time period because of air friction.

2. Position from sea level: Change in position from sea level causes gravitational acceleration to change changes, hence time period changes.

3. Effect of temperature: Increase in temperature causes increase in length of pendulum and hence time period increases.
