il63 [147K]

Answer:

20 m

Explanation:

From the equation of motion,

S = ut+1/2gt²................................. Equation 1

Where S = Height, u = initial velocity, t = time, g = acceleration due to gravity.

Note: Because the rocked is being dropped from a height, acceleration due to gravity is positive (g), and initial velocity (u) is negative

Given: t = 2.0 s, g = 10 m/s², u = 0 m/s (dropped from height)

Substituting into equation 1

S = 0(2) + 1/2(10)(2)²

S = 5(4)

S = 20 m

Hence the height of the the cliff above the pool is 20 m

"which phenomenon of light explains the separation of light into colors in a rainbow
kenny6666 [7]
Separation of light into different color is called "dispersion". Rainbow, comes from refraction and reflection of sunlight, in the falling raindrops, which means that that the refractive index of water depends on the wavelength of light.
