Answer 1

Solution :- Given Liquid 't is have a higher surface tension and higher viscosity than liguid B. Experiment i To flow at same rate (ie 4.6 mb/s) through the same diameter of tubel le 24.0mm) Liquid A required higher Pressure than liquid B required. Thus, PA will be greater than PB. Experiment 2 - Since liquid A has higher surface tension than liquid B. this means; Liquid A has greater tendency to hold the mass at surface of liquids than liguid Be this implies that MA will be greater than ma Ans )
