Answer:
0.76 rad/s^2
Explanation:
First, we convert the original and final velocity from rev/s to rad/s:
Now, we need to find the number of rads that the tire rotates in the 250m path. We use the arc length formula:
Now, we just use the formula:
The resistance of the cylindrical wire is .
Here is the resistance,
is the length of the wire and
is the area of
cross section. Since the wire is cylindrical
.
Comparing two wires,
Dividing the above 2 equations,
Since
The above ratio is
We also have,
The current through the Silver wire will be 4.23 times the current through the original wire.
