Question

measurement of physical quantities are expressed in terms of units which are_______________value?
​

Answer 1

Answer:

Hello Dear.

The correct answer is (d) n ∝ 1/u

Reason/Explanation:-

-Let us take an example of mass ,suppose if a body has a mass of 20 kg . (In this 20 is the numerical value and kg is the unit) So if we decrease the size of the unit , Say kg to g then the numerical value will be 20000.

20 kg = 20000 g.

-If the size of the unit Kg will be increased from kg to Quintal then the numerical value will be 0.2 .

20 kg = 0.2 Quintal.

from this example we can say that if the unit is increasing then the numerical value is decreasing & if the unit is decreasing then the numerical value of is increasing.

∴ numerical value, n ∝ 1/u

Thus it is proved.

Hope it Helps.
