1. A rectangular plateof dimensions 6*4 and thickness 2mm is placed with its largest face flat on the surface of water. Find the downward force on the plate due to surface tension, surface tension of water is 7*10^-2.
2. I f the normal density of sea wateris 1.00g/cm, what will be its density at a depth of 3km?
Given, compressibility of water=0.000048 per atmosphere, 1 atmospheric pressurre= 1.01*10^6 dyne/cm^2
