It takes 525 J of work to compress a spring 25 cm. What is the force constant of the spring (in kN/m)?

1.680kN/m

Explanation:

Work done by the spring is expressed as shown:

where:

k is the spring constant

e is the extension

Given

W = 525Joules

extension = 25cm = 0.25m

Substitute into the formula:

Hence the force constant of the spring is 1.680kN/m

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
