Supply the missing information in figure (a).

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 = 5 cm

Output = 5 cm

We know, input × stretching power = output

5 × stretching power = 5

Stretching power = 5/5

= 1

= 2⁰

Therefore, the missing information is 2⁰.
