B) Define Scalar and vector quantities; in each case give an example.
A) there are seven fundamental physical quantity in measurement.
example- amount of matter present in the body
example- the distance from the Earth to Sun is 1.49*1011m
example- total time of a day is 24hr= 86400sec
example- the temperature of the sun 5778K
v) amount of substance
vi) electric current
vii) luminous of intenticity
Scalar- the physicl quantity which has only magnitude is called a scalar quantity.
Example- speed, distance, work , energy, pressure
Vector- the physical quantity which has both magnitude and direction is called a vector quantity.
Example- velocity, mometum, force, acceleration
