Answer:
Weight of 12 ounces will stretch spring of 15 centimeters.
Step-by-step explanation:
Given:
The amount a spring stretches varies directly as the weight of the object attracted to it.
An 8 ounce weight stretches a spring 10 centimeters.
Now, to get how much weight will stretch it is 15 centimeters.
According to question:
A spring of 10 centimeters stretches a weight of 8 ounce.
Then a spring of 1 centimeter stretches a weight of = [tex]\frac{8}{10}=0.8\ ounce[/tex].
So, a spring of 15 centimetres stretches a weight of = [tex]0.8\times 15=12\ ounces[/tex].
Therefore, weight of 12 ounces will stretch spring of 15 centimeters.
