Question

a cylindrical tank of 1metre radius rests on a platform 5m high.intially the tank is filled with water to a height of 5m.a plug area 10to the power of-4 m square is removed from an orifice on the side of a tank at the bottom.what is initial speed with which water strikes ground​

Answer 1

Answer:

Explanation:

so we can say that water fall with a velocity when it touches the ground now when the water leaves the orifice it will have a velocity (2gh)^1/2

so 2*5*10^1/2

which is 10

now apply laws of motion

v^2=U^2 + 2gs

 so v^2= 100+ 2*10*5

so 200^1/2

is 14.14m/s
