<u>Answer:</u>
a) Height of cliff = 44.145 meter
b) 7.5 meter far from its base the diver hit the water.
<u>Explanation:</u>
We have equation of motion ,
, s is the displacement, u is the initial velocity, a is the acceleration and t is the time.
Diver's vertical motion:
Initial velocity = 0 m/s, acceleration = 9.8
, we need to calculate displacement when time is 3 seconds.

So height of cliff = 44.145 meter.
b) Diver's horizontal motion:
Initial velocity = 2.5 m/s, acceleration = 0
, we need to calculate displacement when time is 3 seconds.

So 7.5 meter far from its base the diver hit the water.
Hmmm the only formula i know is v = d * t or volocity = distance * time
It is released in the atmosphere by chemicals
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the sun
Answer:

Explanation:
The incident angle is
so the reflected ray will also be
.
The normal divides the angle between the incident and reflected ray. So, the angle between them would be

So, the angle between the incident and reflected rays is
.
