Answer:
the angle of the prism = 30 degrees
Explanation:
The angle of minimum deviation for a prism =
<em>for an equilateral prism, A=60∘</em>
<em />
This gives us
taking the Arcsin of both sides we have
Recall that the angle of the prism is equal to the angle of minimum deviation.
Hence, the angle of the prism = 30 degrees

Explained
Explanation:
Big Bang happened about 13.7 billion years ago. It is most accepted theory of universe creation. Several experiments have confirmed the happening of big bang back then, in promising way. One of this experiment is the red shift experiment. A scientist named Edwin Hubble tried to study the spectrum of stars. He made a shocking revelation that universe is rushing outwards in all directions. Light travelling away registers on the red side. He observed that the distance stars showed red shift in accelerated manner. If the universe is accelerating that means, at one point it would have been smaller, in fact it was as small as an atom, some how it exploded and lead to formation of the expanding universe.
Answer:
Explanation:
Power (p)= 40 watt
time (t)= 3 minutes = 180 seconds
Energy (E)= ?
we know
P = E/t
40 = E / 180
E = 7200 Joules
Therefore it does 7200 joules of work.
hope it helps :)
Answer:
(4) The particle travels with a constant velocity until t0 and then comes to rest.
Explanation:
Uniform rectilinear motion is defined as the motion of a particle in a straight line with constant velocity, that is, there is no change in velocity over time.
And this can be determined by means of the following equation:
where:
x = final point [m]
xo = initial point [m]
v = velocity (slope) [m/s]
t = final time [s]
to = initial time [s]
So the slope in the graph gives the constant velocity
Therefore, after the time to there is no displacement, that is the particle comes to rest.
Electromagnetic force. It is where alike forces ( negative, negative & positive , positive) repel and opposite forces ( negative & positive ) attract.
