Plz solve the question.
A narrow, U-shaped glass tube with open ends is filled with 25.0 cm of oil (of specific graity 0.80) and 25.0 cm of water on opposite sides, with a barrier separating the liquids (Fig. below)
(a) Assume that the two liquids do not mix, and find the final heights of the column s of liquid in each side of the tube after the barrier is removed.
(b) For the following cases, arrieve at your answer by simpel physical reasoning, not by calculations :
(i) What would be the heigh on each side if the oil and water had equal densities?
(ii) What would the heights be it the oil's density were much less than that of water?

A square metal plate 0.180 m on each side is pivoted about an axis through point $O$ at its centre and perpendicular to the plate (Fig. below). Calculate the net torque about this axis due to the three forces shown in the figure if the magnitudes of the forces are $F_1 = 24.0 N, F_2 = 15.8 N,$ and $F_3 = 15.5 N$. The plate and all forces are in the plane of the page.
