The actual answer is 7/100
Answer:
Work done,W= 250J
Displacement , s = 60
We know that, Work done = Force x displacement
i.e , W = Fxs
250 J = F x 60m
F = 250/60
=4.16 N
Hence , 4.16 N of Force is applied on the body.
The correct answer is b , the the liquid with heat and cool faster
Good conductors of electricity have larger conductivity values than insulators.
A material that obeys Ohm's law reasonably well is called an ohmic conductor or a linear conductor.
The resistance of a conductor is proportional to the conductivity of the material of which the conductor is composed.
Answer: Options 1, 2 and 4.
<u>Explanation:</u>
In physics and electrical engineering, a conductor is an article or kind of material that permits the progression of charge in at least one headings. Materials made of metal are basic electrical conduits.
Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Most atoms hold on to their electrons tightly and are insulators.
