1. The problem statement, all variables and given/known data

A glass tube is bent into a rectangular "U". Find expressions for the difference in the height hbetween the tops of the liquid columns when (a) the tube has linear acceleration a in the direction of the x-axis, (b) when the tube has uniform angular velocity ω about the y-axis.

2. Relevant equations

F=ma, density

3. The attempt at a solution

I have been working on this problem for days and am stuck. my physics teacher wont help me. [aL]\frac{}{}[/g] i think this is an expression for the first part but im not sure how to get to it.
