Explanation:
c )
First of all we shall calculate the velocity of bullet just after the collision with the pendulum by applying conservation of momentum law.
v₂ = mv₁ / ( m + M )
v₂ is velocity after the collision , m is mass of bullet v₁ is velocity of bullet and M is mass of pendulum.
v₂ = .030 x 185 / 3.18
= 1.745 m /s
Let the angle of the pendulum’s maximum displacement with the vertical be θ
height attained by the pendulum h = L ( 1 - cosθ) ; L is the length of the string.
Applying conservation of mechanical energy law
mgh = 1/2 m v₂²
m is mass of (bullet+ pendulum) , v₂ is its velocity
g L ( 1 - cosθ) = v₂² / 2
9.8 x 2.85 ( 1 - cosθ) = 1.745² / 2
( 1 - cosθ) = .0545
cosθ = .9455
θ = 19 degree
a ) The vertical component of the pendulum’s maximum displacement.
L ( 1 - cosθ)
= 2.85 ( 1 - .9455
= .155 m
b ) Horizontal component : L sin18
= 3.15 x .30
= .97 m .
According to the universal law of gravitation, the force due to gravity is a. inversely proportional to the square of the distance between objects.

What is the universal law of gravitation?</h3>
Newton's law of universal gravitation states that objects are attracted to each other in the universe with a force directly proportional to the product of their masses and inversely proportional to the square of their distance apart.
The equation that represents this law is;
F = G × M1M2 ÷ r∧2
Where,
F is the gravitational force acting between two objects
M1 and M2 are the masses of the objects
r is the distance between the centers of their masses
G is the gravitational constant.
Thus. according to the universal law of gravitation, the force of gravity is inversely proportional to the square of the distance between objects.

If i was feeling harsh today, I'd say the answer to your question is impossible to obtain due to the fact that photons do not emit radiation, photons ARE the radiation emitted. Though for the sake of it, here is the method...
<u>The simple method:
</u>
E=hf
therefore f=e/h
f=(3.611x10^-15) / 6.63x10^-34)
