is the time taken by the transducer to detect the reflected waves from the metal fragment after they were first emitted
Option C
<u>Explanation:</u>
Given data:
speed, v = 1300 m/s
distance, d = 3.0 cm = 
We need to calculate the time taken by the transducer to detect the reflected waves from the metal fragment after they were first emitted.
As we know, the velocity is the ratio of distance and the time travelled by an object. The equation form is given by,

By applying the given values to the above equation, we get


Pros -
It doesn't cost much
Power stations are very compact
Transportation of the material is easy
Cons-
It's not safe
Nuclear waste take 200 years to degrade
Greater risk of explosion
