Answer:
Explanation:
We have the following relation between power, P and intensity, I
=
=
We also have the following relationship between electric field and electromagnetic radiation thus
Hence
substituting the values of I, c and e, we have
- initial velocity=u=0m/s
- Final velocity=v=4m/s
- Time=t=0.5s
Answer:
the tangential velocity of the student is 4.89 m/s.
Explanation:
Given;
the radius of the circular path, r = 3.5 m
duration of the motion, t = 4.5 s
let the student's tangential velocity = v
The tangential velocity of the student is calculated as follows;
Therefore, the tangential velocity of the student is 4.89 m/s.
