Answer:

1.997s = 2.0s

Explanation:

From equation of motion,

S = ut + 1/2 gt²

u = 0 m/s

t = ?

g = 9.8 m/s²

S = 1955cm = 19.55m

19.55 = 0 + 1/2 * 9.8 * t²

19.55 * 2 = 9.8t²

t² = 19.55 * 2 / 9.8

t² = 3.987

t = (3.987)^½ (take the square root of both sides)

t = 1.997s = 2.0s

Surface tension - My definition -

It's exactly what it says - The tension of a surface with a liquid (such as water), caused by the attraction of the surfaces layer ---- I hope this helps ---- I actually did research it and got some of this from a dictionary, but I changed some of it, too.... Sorry if this doesn't help :)
