? How am I thinking about this wrong? E = V/d, d decreases and E becomes larger.

For c) iii), why did they add a /f for volume?

How did you get through this algebra? " ##\sqrt{h^2+w^2}-1##, giving a vertical force component of ##kh(1-(1+\frac{h^2}{w^2})^{-\frac 12})## per spring. For small h this approximates a total force of magnitude ##k\frac{h^3}{w^2}##. "

Still don't see why you were writing p+d/2 / p-d/2 when it is 11/9 for 10+- 1 (where I assume 1 is d). Largest possible value would be p+d/p-d, would it not?

Yes.

So we don't consider the weight of water, but look at is as buoyancy?

gravity and normal force. was wondering how torque and linear force differs, that's why I provided my explanation.

What exactly is the difference? With the single linear force there is compression of the circle and with torque it just rotates about the spot?

Why is there hysteresis?

## \frac {-b \pm \sqrt{b^2 -4ac}} {2a} ## - why does this not work?

12b) was fine, I could do it, was not sure about the -k/m x becoming - k/m 0 or how they get the equations for the first few lines. Will look at it again. How would I observe latex code in non-linear form when typing? i.e. \ frac a b isn't in text.

Was referring to the weight of the water on top of his body, because he is submerged (i.e. below water level).

nope, I don't see why it wouldn't be the same % for each wavelength, i.e. straight line distribution.

Wait how is 10+/-1 with 11/9 = (P+d/2)/(P-d/2). Why not P+d/P-d
