The wire connected to the DC source doesn't emit electromagnetic waves.
The electromagnetic wave is an oscillation of electric fields and magnets field that sustains each other, this wave time has the characteristics that it can travel without a material medium, for which they are of extreme importance.
It is caused by DC sources such as batteries only having a constant voltage, it is different from AC sources which have different voltage over time, AC voltage can induce the wire because AC sources have magnetic flux change. DC sources don't have magnetic flux change so they don't emit electromagnetic waves.

I dotn know sorryyyyyyyyyyy
Answer:
Ensure each member of the audience can see and read the aid.
Explanation:
Correct Answer: Option C
<em>Explanation
</em>
X = ut + 12at2
= (0 x 4) + (12 x 0.1 x 4 x 4)
= 0.8m
workdone = force x distance
= 40 x 0.8
= 32J
