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

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

Define system of units ? Give the name of various system of unit?

Ans 1: System Units:A complete set of unit for all physical quantities is known as system of units .
Explanation:There are several system of unit For example
Foot - pound - system ( FPS)
Meter - kilogram -second system (MKS )
Centimetre - gram - second system (CGS )
But the most popular system id the system international (SI)
System International(SI):In 1960 on international committee agreed on a set of definitions and standards to describe the physical quantities. The system that was established is called system international (SI)
The system international is used throughout the world. Its unit are convenient for daily use .
The system international is build-up from three kinds of unit
- Base Unit
- Derived Units
- Supplementary Units

Question # 1

Differentiate between Base Units and Derived Units.

Ans 1: Base Units:The units associated with the base quantities are called base units. Other units are derived from base units . There are meter, Kilogram, second, candela, mole, ampere, kelvin.

Derived Units:The units associated with the derived quantities are called derived units. SI units for measuring all other physical quantities are derived from the base and supplementary units. For example , newton, joule,watt and pascal are derived units.

Question # 1

Name two major types of errors in measurement and also define them.

Ans 1: The major types of errors in measurement are Systematic Error and Random Error.

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
Ans 2: Random Error: Random error occurs when repeated measurements of a quantity give different values under the same conditions. This error is due to faulty procedure or negligence and inexperience of person at the time to start or stop the stop watch. This can be reduced by taking average value of observed readings .

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
