Question

The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters. Which equation relates the mass of the object, m, and the length of the spring, s?

Answer 1

hi.
your answer is s=3/10m
hope this helps!!!

Answer 2

The required equation is
`s=(3)/(10)m`

Explanation:

Given: The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters.

To find : Which equation relates the mass of the object, m, and the length of the spring, s?

Solution :

Let the mass of the object m,

Length of the spring s,

When a 30-gram object is attached, the spring stretches 9 centimeters.

i.e, the times length of the object is attached to spring is
`(9)/(30)=(3)/(10)`

The length of a spring varies directly with the mass of an object that is attached to it.

According to question,

`s=(3)/(10)m`

i.e, length of the spring is 3 by 10 times the mass of the object.

Therefore, The required equation is
`s=(3)/(10)m`
