Question

The numerical value of a given quantity A) independent of unit B) directly proportional to unit C)inversly proportional to unit D) directly proportional to the square root of the unit

Answer 1

Numerical value of a given quantity:1)Independent of unit,ie. Dimensionless. Example is Curie ,Nuton,SI unit of radioactivity is : a) Rutherford b) Roentgen c) Becquerel d) Curie ,e)Reynold number of turbulent flow given by the DV ρ/μ .

This comprise of diameter of the pipe, velocity of the liquid through the pipe divided by viscosity of the liquid passing through the pipe.

2)Directly proportional to the unit : Monitory unit 100 rupees,1000 rupees.

3)inversely proportional to unit, velocity, 100 m/sec =27.7 km/hr.

4)side length of a square related to its area directly proportional to the sqare root of the area of the square.
