Question # 1

Define and explain supplementary units?

Ans 1: The general conference on Weights and Measures has not yet classified certain unit of SI under either base or derived units. These SI units are called supplementary units.
Radian and Steradian are supplementary units.
Radian: The radian is the plane angle between two radii of a circle which cut off on the circumference an arc, equal I length to the radius. It is two dimensional angles.
Steradian: The Sterdian is the solid angle subtended at the center of the sphere by an area of its surface equal to the square of radius of the sphere. It is three dimensional angles.

Question # 1

Define error and uncertainty ? Discuss the various types of error ?

Ans 1: Error:The difference between measured value and actual value is known as error.
Uncertainty:The errors which a rises due to natural imperfection of the experimenter the limitation of the apparatus and the change in the environment during the measurement is known as Uncertainty
Types of Errors:There are three type of errors which are given below.
1. Personal Error:The error due to carelessness or improper knowledge about an instrument or incorrect reading of a scale by an experimenter is known as personal error. The personal error can be removed to some extent error if the experimenter take care during the measurement of any quantity and have proper knowledge about the measuring instrument.
2. Systematic Error:The error due to faulty apparatus and poor calibration of the instrument is known as systematic error. The systematic error also a rises from zero error between scales as in vernier caliper screw gauge and spherometer. The systematic error can be removed by comparing the faulty instrument with some accurate and standard instrument. the difference of the two can be added tracted to the measurement if the error is positive then will be subtracted from faulty instrument reading for correctness. If the error is negative, then it will be added to the foulty instruments reading for correctness
3. Statistical Error:The error due to repeated measurements of same quantity under same condition that result in different values of the same quantity is known random error.
