Question # 1

Define systematic errors. Explain how can we remove the effect of systematic errors?

Ans 1: Systematic Errors: Systematic errors occurs when repeated measurements of a quantity give the same values under the same conditions.
This error is due to poor calibration or zero error in the stop watch. This error can be removed by applying correction factor.

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

How many nanoseconds are there in 1 year?

Ans 1: As 1 year = 3.136x10^{7 s}
1 year = 3.1536x10⁷ X1s
1 year =3.1536x10⁷x10⁹x10^-9s
1 year =3.1536x10⁷x10^-9ns
1 year =3.1536x 10¹⁶ns

Question # 1

Differentiate between the precision and accuracy.

Ans 1: Precision: A measurement which has less absolute uncertainty is called precise measurement. The precision of a measurement is determined by the instrument being used.Absolute uncertainty , in effect, is equal to the least count of measuring instrument.
Accuracy: is the one which has less fractional or percentage error. Accuracy measures,how close a measured value is to the actual value.
