Question

height of a body is measured as AB in one system and as CD in another system.A,C are numerical values B, D are units. If A/C=100,then B/D=​ a)100 b)1/100 c)1 d)zero

Answer 1

Answer:

b) 1/100

Explanation:

suppose the heigt of body measured in AB is 100cm and CD is 1m . so a/c = 100/1 = 100

and b/d = 1 cm/ 1m = 1cm/100cm = 1/100

Answer 2

Concept:

Comparing a physical quantity to a recognized standard quantity of the same kind is the process of measurement.

Height is the distance between the top and bottom or the base and the object.

Given:

In one system, height is measured as AB and as CD in another system.

The value of A/C = 100.

Find:

The value of B/D.

Solution:

The height measurement is assumed to be AB in one system and CD in another.

B and D are the units used to measure the height, while A and C are the numerical values.

Given that the same person's height is represented by both AB and CD, their ratio will be equal to 1.

Therefore,

$\frac{AB}{CD}=1$

$\frac{A}{C}\frac{B}{D}=1$

We have, $\frac{A}{C}=100$

$100(\frac{B}{D})=1$

$\frac{B}{D}=\frac{1}{100}$

The value of B/D is 1/100.
