Aforce of 10 n stretches a particular spring by 2 cm. how far would a 20 n force stretch that same spring? a force of 10 n stretches a particular spring by 2 cm. how far would a 20 n force stretch that same spring?
a. 20 cm
b. 4 cm
c. 8 cm
d. 2 cm

Explanation:

Given that,

Force acting on the spring,

Stretching in the spring,

Force acting on the spring,

Stretching in the spring,

To find :

How far would a 20 N force stretch that same spring?

Solution,

For the same spring, the value of spring constant must be same. The relation between the force and the spring constant is given by Hooke's law as :

F=kx

Hence, the 20 N force stretch by 4 cm.  

are there answer choices to this question? this seems like a question where you have options to choose from.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
