In the diagram below, a student compresses the spring in a pop-up toy a distance of 0.020 m. if 0.068 j of energy are stored in the toy, what is the toy’s spring constant? a) 120 n/m b) 170 n/m c) 225 n/m d) 340 n/m

option d) 340 N/m

Explanation:

Energy stored in the spring of the toy,

 ( given)

Where, k is the spring constant and x is the length of the string after compression.

x = 0.020 m

Then spring constant,

Thus, the spring constant of toy is 340 N/m. Correct option is d.

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

i think the answer is a, hope this is right, that would be my best guess.
