Question

which of the following sets cannot enter into the list of fundamental quantities is a system of units?
A . length,mass and velocity
B. length,time and velocity
C . mass,time and velocity
D. length, time and mass.​

Answer 1

Required Answer:-

There are 7 fundamental quantities from which units of other quantities are derived. The set of these quantities are:

1. Length
2. Mass
3. Time
4. Temperature
5. Amount of substance
6. Electric current
7. Luminous intensity.

In option a,b and c, velocity is given. Velocity is derived from the relation of distance and time because it is the rate of distance covered. Hence, it's not a fundamental quantity. Thus, A,B and C cannot enter into the list of fundamental quantities is a system of units$.$

$\large\underline{\underline{\maltese{\blue{\pmb{\sf{ \: Answer :-}}}}}}$

➻ In A , B and C velocity is given which is deprived from the relation of distance and time because it is the rate at which distance is being covered .For e.g , 24 m/s .

➻ Therefore :

A,B and C cannot enter in the list of fundamental activities .
