Question # 1

Explain " Rounding off numbers ?

Ans 1: The quantities in a measurement are always rounded off to certain level of accuracy. The following rules must be observed while rounding off a number.
1. If the dropping digits is less than "5" then the last retained digit is kept as it is For example 863.73 is rounded to 863.7
2. If the dropping digits is greater than '5' then the last retained digits is increased by '1' for example 9.66 is rounded to 9.7
3. If the dropping digits is '5' and the last retained digit is even then it will be remain uneffected. For example 66.45 is rounded to 66.4
4. If the dropping is '5' and the last retained digit is add, then it will be increases by '1' for example 76.35 is rounded to 76.4

Question # 1

Give the drawbacks to use the period of pendulum as a time standard.

Ans 1:
The value of time periods of a simple pendulum depends upon its length and gravitational acceleration. So, the following drawbacks will be observed.
- The value of g varies with altitudes
- Length of the pendulum varies due to the increase or decrease in temperature .
- Air resistance will affect the time period.
