Answer:
The required equation is
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 The length of a spring varies directly with the mass of an object that is attached to it.
According to question,
i.e, length of the spring is 3 by 10 times the mass of the object.
Therefore, The required equation is
