А A pool of water of refractive index
babymother [125]

Answer:

Apparent depth = 45 cm

Explanation:

The refractive index of water in a pool, n = 4/3

Real depth, d = 60 cm

We need to find its apparent  depth when viewed vertically through  air.​ The ratio of real depth to the apparent depth is equal to the refractive index of the material. Let the apparent depth is d'. So,

n=\dfrac{d}{d'}\\\\d'=\dfrac{d}{n}\\\\d'=\dfrac{60}{\dfrac{4}{3}}\\\\d'=45\ cm

So, the apparent depth is 45 cm.

A student drops a rock from a bridge to the water 12.7 m below. with what speed does the rock strike the water? the acceleration
kolezko [41]

The rock strike the water with the speed of 15.78 m/sec.

The speed by which rock hit the water is calculated by the formula

v=\sqrt{2gh}

v=\sqrt{2*9.8*12.7}

v=15.78 m/sec

Hence, the rock strike the water with the speed of 15.78 m/sec.
