Answer:
a
b
c
Explanation:
From the question we are told that
The angle of incidence is
The refractive index of water is
Generally Snell's law is mathematically represented as
Here is the refractive index of air with value
is the angle of refraction
So
=>
=>
Given that the angle should not be greater than then the angle of incidence will be
=>
=>
Generally for critical angle is mathematically represented as
=>
=>
Answer:
52 N
Explanation:
Given:
Work done= 1820 J, distance= 35 meters Force = ?
Formula for work done
W = F • d
Find F.
F = W / d
Substitute the given into the equation.
F = 1820 J / 35 m
= 52 N
Nicolaus Copernicus was the one who brought astronomy out of the dark ages.
In one of his books "On the Revolutions of the Heavenly Bodies", he published the renowned line which declares his theory.
Nicolaus Copernicus, A polish astronomer put forward the theory that the is th Sun one that rests in the middle or center of the Universe and the planet Earth revolves around it on its axis every day.which was considered to be called the Heliocentric system.

Answer:
Explanation:
Given
Amplitude of oscillation is A
spring constant k
suppose m is the mass of block so its natural frequency of oscillation is given by
When three identical springs is connected in series
Natural Frequency becomes
Thus maximum speed with Amplitude A is
so by a factor of maximum velocity is changed
Answer:
The center of the Milky Way most likely contains a supermassive black hole.
Explanation:
Because it is an eleptical galaxy, it has a little rotation to it but not enough to flatten out so the center will contain a supermassive black hole.
