Springs - simple harmonic motion

[tascja]

my question is: is there a way to find the work done to a spring when the only variable given is the distance (x)??

Homework Statement

For the pressure gauge, what work is done by the air on the spring?

Homework Equations

W = 1/2kx²
F_x = kx

The Attempt at a Solution

I can't really attempt anything because i don't have k, its not given and I am not sure how to find it??

If it is a pressure gauge what is it you would expect such a device to do? Will it measure say something like the pressure of the air? When it does that will it give a reading? What work will the air have done to affect that reading from the normal state?

Is there a diagram and more to the problem or just a general question about what work air pressure does inside a gauge?

The question doesn't give any other information so i think your right, they just want a general answer. thanks i was freaking out because they didnt give enough info!
