Answer:
The required equation is [tex]s=\frac{3}{10}m[/tex]
Step-by-step 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 [tex]\frac{9}{30}=\frac{3}{10}[/tex]
The length of a spring varies directly with the mass of an object that is attached to it.
According to question,
[tex]s=\frac{3}{10}m[/tex]
i.e, length of the spring is 3 by 10 times the mass of the object.
Therefore, The required equation is [tex]s=\frac{3}{10}m[/tex]
