Answer:
0.0375 ohms
Explanation:
The resistance of a material is the product of the resistivity of the material by the length of the material divided by its cross-section area.
Mathematically,
resistance= resistivity × length/area
In this case the resistivity of the material is the same, and the length is the same thus, assume a length of 1 unit, the cross-section area is the one changing
In applying the formula,
resistivity is r and length is l=1 unit, find the resistivity the material as;
resistance= resistivity * length /area
0.075=r*1/1.04
0.075=r*0.9615
0.075/0.9615 =r
r=0.078
use the r=0.078 , a length of 1 unit (assumed), and area of 2.08 mm² to find the new resistance
Resistance= resistivity * length /area
Resistance = 0.078*1/2.08
Resistance= 0.078 * 0.4807 = 0.0375 ohms
Point to note here is that the greater the cross-section area, the less the resistance.

The question is incomplete, the complete question is:
Which of the following is not a reason to give yourself extra "cushion" when driving?
A. Poor visibility B. Poor road conditions C. Inclement weather D. None of these.
The correct answer is D. None of these.
Explanation:
All the options are not reasons to give yourself an extra cushion when driving, rather they are reasons that are not favorable to driving at all.
A cushion is a certain amount of distance you are supposed to keep between you and the car in front of you to allow easy maneuvering in any condition.
A typical cushion is 3 seconds between you and the car in front of you, in less than perfect conditions like bad weather or poor road conditions an additional second must be added to it.
