Question

Four springs are stretched to the same distance from the equilibrium position. The spring constants are listed in the table.

Answer 1

Answer:

B.) X,W,Y,Z

Explanation:

The elastic potential energy equation is:

PE = (1/2)*k*x²

where x is distance and k is the spring constant. Then, as k increases, PE also increases, so, the greatest potential energy corresponds to the greatest k, and vice versa.

Answer 2

The Hook's law states that F=Ke, where 
F⇒force applied to the spring,
e⇒extension of the spring and 
K⇒spring constant. 
Spring constant determines the strength of the spring. The larger the spring constant the stronger the spring it is. 
The list from the greatest to list is: 

X, W, Y, Z
