A = volt is termed used for measuring voltage And also equal to joule/coloumb
B=Henry is unit of inductance
C = Joule/carlorie is mks unit of mechanical equivalent of heat
D =joule is unit of heat

A a Modulus of rigidity means Modulus of Velocity
B=latent heat
C = angular momentum
D=torque

C=Wb/m = magnetic flux density
B = Simemens
D = magnetic flux

a=Watt =Slunit of power = J/S
b= Kilowatt = Equivalent to one kilowatt of power extended for one hour
c = Horse power = 1 hp = 746 watt

a=Work is measure of quantity that is capable of accomplishing macroscopic motion of a system due to the action of a force over a distance. W = F.d
b= Pressure = F/A = N/m2 = Pascal
c= Volume is three dimensional space enclosed by some closed boundary.
d= Area is two dimensional plane

Imm= 10^3m
1angstrom = 1.0x 10-10 meter
1 Fermi = 10^-15 meter

Because Debye is unit in CGS of electric dipole moment

Compare the dimensions

a.= Kinematics: Properties of object when in motion
b. = Mechanics: Deals with motion and force producing motion
c.= Statics: Branch of mechanics concerned with bodies at rest and forces in equilibrium.
d= Modern Physics: Deals with the underlying structure of smallest particles in nature.

International agreement defined the meter length in terms of wavelength of light emitted from the krypton.

Zeros to the left side of non-zero digits are non-significant.

Absolute uncertainty is called absolute error, it is size of range of values in which the “true value” lies.
