Question

Problem 5a

Answer 1

Given information

Given values:

Mass of the fish,  

Stretch in the scale,  

 

Formula used:

The force on the scale is equal to the weight of the fish

 

Here,

            is the mass of the fish

            is the acceleration due to gravity

The stiffness of the spring is

 

Here,

            is the force on the scale

            is the stretch in the fish scale

 

Step-by-step explanation

Step 1.

A spring scale, sometimes known as a spring balance, is a weighing scale with a vertical spring linked to a hook. The weighing object is fastened to the hook. The vertical spring will be stretched by the item. The spring will strive to return to its previous shape by exerting a restoring force. The stretching continues until the spring's restoring force perfectly balances the hanging weight.
