Acompressed spring has 16.2 j of elastic potential energy when it is compressed 0.30 m. what is the spring constant of the spring? 90 n/m 108 n/m 180 n/m 360 n/m

360 N/m

Explanation:

The elastic potential energy of a spring is given by

where

k is the spring constant

x is the compression/stretching of the spring

In this problem, we know the elastic potential energy, E=16.2 J, and the compression, x=0.30 m. Therefore, we can re-arrange the formula to calculate the spring constant k:

your answer is, orbit around the nucleus

find the surface area of the sphere to the nearest square unit. use a calculator.
