Answer:
81.6 ohm
Explanation:
For a cable type conductor, the resistance is given by the following formula:
Where:
The problem doesn't give us additional information about resistivity or the cross section of the wire, so let's assume:
Then, in this case, the resistance of the cable depends only on the length. Therefore, if its resistance was originally 27.2 ohms, if we triple its length, it makes sense that its new resistance is three times the original. Thus:
<u>Option (d)</u>
<u>Explanation:</u>
The statement that could be an example of properly written long-term goal is Each week I am going to add .25 miles onto my run so i can reach a total of 5 miles by the end of this month.
It is corresponding to long term portrayed by the statement is, every week if the student is targeting for a goal and aims to complete 0.25 miles on his long run, by the end of the 4th week of the month, he would have achieved 5 miles of his long term target.
