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.

Question # 1

What dose the word "micro" signify in the words "micro wave oven ?

Ans 1: Micro means very small. Micro waves have the shortest wavelength of all the shortest wavelengths of all the radio waves, therefore, these are known as microwaves. Now like all electromagnetic waves the microwaves produces heating effect when their energy is absorbed. It is because, due to shorter wave length the micro waves posses high frequency and maximum energy.

Question # 4

What do you mean by significant figures ? Give the rules for determining significant figures ?

Ans 1: Significant Figures:The combination of accurately known digits and the first doubtful digits during a measurement are known as as significant figures
Rules for determining significant figures:
1. All non-zero digits from '1' to '9' are significant for example in 36.473 m there are five significant figure
2. All zero between two non-zero digits are significant for example in y= 4.03 m there are three significant figures
3. The zero to the right of a decimal symbol and to the left of non-zero digits are not significant
4. All zero to the right of a decimal appears after non-zero digits are significant
5. In case of scientific notation the figures before the power of ten are significant
6. In case of addition and subtraction the result obtained is retained to the measurement which is least precise in the data
7. In case of multiplication and division the final result is retained to the measurement which contains the last number of significant figure
8. In case of rounding of non-significant figures the following rules should be followed.
- IF the dropping digits is less than '5' then it will be just ignored For example 863.73 is rounded to 863.7
- If the dropping digits is greater than '5' then the last retained digit is increased by '1' for example 8.76 is rounded of 8.8
- If the dropping digits is '5' and the last retained digits is even then it will remains uneffected. for example, 56.45 is rounded to 56.4
- If the dropping digits is '5' and the last retained and the last retained digits is add than it will be increased by '1' for example 46.35 is rounded to 46.4

Question # 1

Define the term error, uncertainty precision and accuracy in measurements?

Ans 1: Errors:The difference between measured value and actual value of a quantity is known as Error.
Uncertainty:An estimate of the possible range of an error is known as uncertainty. (OR)
The error which arises due to natural imperfections of the experimenter, the limitations of the apparatus and the changes in the environment during the measurement is known as uncertainty.
Precision:The measure of the consistency of measurements is known as precision. It requirements the magnitude of error in measurements.
Accuracy:The measure of correctness of a measurements is known as accuracy"
The Accuracy means to check how the measure values is closer to the actual value It is a relative is closer to the actual value.It is a relative error. it can be obtained by dividing the error with measured quantity The accuracy depends on the error is greater than smaller will be the accuracy of the measurement can be increased by taking several reading and then take their average

Question # 1

Are radius and steradian the basic units of SI? Justify your answer?

Ans 1: Radian and steradians are not the basic units of SI. These are the units of purely geometrical quantities i,e plane angle and solid angle respectively. The general conference on weight and measures has not yet classified there units under either base unit or derived units these are called supplementary units.
