Please explain this MCQ Asap

pleaes do it correctly my second time post the question

Very small pressure differences p A -p B can be measuredaccurately by the two-fluid differential manometerin Fig. . Density ρ 2 is only slightly larger than thatof the upper fluid ρ 1 . Derive an expression for the proportionalitybetween h and p A - p B if the reservoirs arevery large.

The system in Fig.  is at 20 ° C. Determine the heighth of the water in the left side.

For a liquid with the contact angle of 53.6 degrees and surface tension of 0.075 N/m, capillary rise is 2.50 m. What is the expected capillary rise in meters if the liquid is replaced with another with a contact angle of 12.7 degrees and a similar surface tension? (answer should be accurate to 2 decimal places) Answer:
