The question is a little confusing. An electromagnetic wave is radiation. One doesn’t emit the other. Take another look at the question and write it again please.
Answer:
A.
Explanation:
I think it might be the big number A
120/6=20 ohms :) would be the ans
The relationship between the charge flowing through a conductor, the current flowing through the conductor and the time is:
Q = It
Where Q is the charge, I is the current and t is the time of application of the current. Substituting the values:
48.96 = 1.39 x t
t = 35.2 seconds
Answer:
Any medium or material of high refractive density e.g Water which refracts the light rays 1&2 away from their normal
