-W ay = x +*+1 (C) Xy = x+1 (d) N.O.T. 9.) Water is drained from a vertical cylindrical tank by opening a vaive at the base of the tank. It is known that the rate at which the water level drops is proportional to the square root of water depth y where the constant of proportionality k> 0 depends on the acceleration due to gravity and the geometry of the hole. Iftis measured in minutes and k=1/15, then the time to drain the tank if the water is 4 m deep to start with is (a) 30 min (b) 45 min (c) 60 min (d) 80 min e nombreu1
