 P: 44 1. The problem statement, all variables and given/known data The U tube contains the liquid.The length of the liquid in U tube is L. If U tube has an acceleration a in X-axis and we make liquid a small oscillation.Find the period of oscillation. 3. The attempt at a solution I know the answer is 2$$\pi$$$$\sqrt{\frac{L}{2\sqrt{g2+a2}}}$$ but I don't know how to prove it.So,please help me.
