For pressurized water reactors the coolant is not permitted to boil in the core of the PRW, however the coolant in boiling water reactors is permitted to do so in the core of BWR. Pressurized water reactors have an indirect cycle. Whereas, the boiling water reactors go through a direct cycle. Both are light water reactors.
Newwton's law of inertia states that an object will not be able to move unless force is applied to it
Answer:

Explanation:
Let:

We need to know for which value of
the function
is equal to
:

Therefore, we need to solve for the previous equation for
:
Replacing the values of
and
:

Subtract 4 from both sides:

Multiply both sides by -1

Divide both sides by 3:

Therefore the value of
for which
is
.
Verify the result:

Answer:
Amplitude will be equal to 0.091 m
Explanation:
Given mass of the slits = 41 gram = 0.041 kg
Frequency f = 1.65 Hz
So angular frequency 
Angular frequency is equal to 

Squaring both side

k = 4.40 N/m
For vertical osculation


A = 0.091 m
So amplitude will be equal to 0.0391 m
