Answer:
friction occurs because no surface is perfectly smooth.
Explanation:
rougher surfaces have more friction between them.
The question is incomplete. The complete question is :
A platypus foraging for prey can detect an electric field as small as 0.002 N/C.
-To give an idea of sensitivity of the platypus's electric sense, how far from a +80nC point charge does the field have this magnitude?
Solution :
Given electric field, E = 0.002 N/C
Charge, Q = + 80 nC
or 
R = 600 m
This is the distance of the charge from the point of observations.
Nuclear energy is is used practically for many energy requirements because the reactions are controlled to regulate energy output
<h3>What is nuclear energy?</h3>
Nuclear energy is the energy reaelesed during nuclear relations.
Nuclear energy is a clean form of energy which is available in enormous amounts.
Nuclear energy is is used practically for many energy requirements because the reactions are controlled to regulate energy output.
Therefore, the control of nuclear reactions make the use if nuclear energy possible.
