what is the spring constant of a spring that is compressed by 0.250 cm when a force of 35 n is applied?

a. 140n/cm

b.100n/cm

c.200n/cm

d.150n/cm

a. 140 N/cm

Explanation:

The relationship between force applied, spring constant and compression/stretching of a spring is

where

F is the force applied

k is the spring constant

x is the compression/stretching

In this problem, we have:

x = 0.250 m is the compression

F = 35 N is the force applied

Substituting and re-arranging the equation, we find the spring constant:

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.
