The potential energy of a spring is a. inversely proportional to the square of the amount b. the spring that is stretched from its equilibrium length. c. proportional to the square of the amount the spring that is stretched from its equilibrium length. d. proportional to the amount the spring that is stretched from its equilibrium length.

c) proportional to the square of the amount the spring that is stretched from its equilibrium length

Explanation:

according to Hooke's law, the elastic potential energy of a spring is:

where:

K is the spring constant

x is the distance that the spring's is compressed.

as you can notice the distance is squared, so the energy is proportional to the square of the compressed distance.

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.

explanation:

it is the second option.
