Supply the missing information in figure (b).

Solution:

Given, the figure represents a repeater machine.

We have to find the missing information in the given diagram.

A repeater machine is a hypothetical machine which automatically enlarges items several times.

From the given figure,

Input = 3 cm

Output = 15 cm

We know, input × stretching power = output

3 × stretching power = 15

Stretching power = 15/3

= 5⁻¹

Therefore, the missing information is 5⁻¹.
