Answer:
Explanation:
Resistivity is given by where A is cross-sectional area, R is resistance, L is the length and is the reistivity. Substituting 0.0625 for R, 3.14 × 10-6 for A and 3.5 m for L then the resistivity is equivalent to
Answer:
Explanation:
<u>Work
</u>
The work done by an external force F when moving an object by a distance X parallel to its direction is
The second Newton's law gives us the net force acting on an object of mass m which is being moved at an acceleration a:
Replacing the last equation into the first equation
And solving for a
There seems to be some kind of mistake in the data provided, we'll use it anyway
It's a very small value as compared to the dimensions of the rest of the problem.
