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

How can we reduce random and systematic error?

Ans 1: Reduce random error: Repeating the measurement several times and taking an average can reduce the effect of random error.

Reduce systematic error: The systematic error can be reduced by comparing the instrument with another which is known to be more accurate and a correction factor is applied.

Question # 1

Explain the term " precision" and accuracy ?

Ans 1: The 'Precision represents the magnitude of error in a measurement while the accuracy means to check how the measured values are closer to the actual value. The accuracy represents the relative error. It can be obtained by dividing the error with measured quantity.
The accuracy depends on the error if the error is greater than smaller will be the accuracy of the measurements and vice versa.
The accuracy of the measurements can be increased by taking several readings and take their average.
