Choose the false statement regarding resistance. a) longer wires have less resistance. b) electrical resistance produces heat. c) resistance slows the flow of current. d) the larger the diameter of the wire, the less resistance.

The answer would be:

A. Longer wires have less resistance.

Here is why:

The statement is false because longer wires tend to have greater resistance. Look at the formula of resistance below:

ρ = resistivity

L = length

A = cross-sectional area

As you can see Length of the wire is directly proportional to the resistance, which means as the Length increases, the Resistance increases.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
