What would increase the resistance of a copper wire?

1 answer:

3 0

R = ρl/A

From the equation above R = Resistance, l = length, A = Cross Sectional Area of wire.

From the equation, it can be seen that R would increase if the wire's area is reduced.

If the area of the wire is reduced, means the same thing as:

<span>A. decreasing the wire’s thickness</span>

(a) Suppose that a NASCAR race car is moving to the right with a constant velocity of +93 m/s. What is the average acceleration

Doss [256]

A. the average acceleration would be 0 since there is no change in velocity

b. Average acceleration = change in velocity/time

93- (-93)/12

= 186 /12

= 15.5 m

vladimir1956 [14]

I think F= mv²/r
And F=ma
So, ma = mv²/r
a = v²/r
a = 100/5
a = 20 m/s
