Consider two copper wires. one has twice the length and twice the cross-sectional area of the other. how do the resistances of t
Anestetic [448]

Answer:

R = ρ L / A     where R is the resistance and ρ the resistivity:

R2 / R1 = (L2 / A2) / (L1 / A1) = L2 * A1 / (L1 * A2)

R2 / R1 =  (2 L * A) / (L * 2 A) = 1

Their resistances should be the same.

If you walk across a nylon rug and then touch a large metal object such as a doorknob you may get a spark and a shock. Why does
k0ka [10]

Answer:

Explanation:

  • You are more likely to be shocked during dry days than humid days because during humid days more water is in the air, and water being a good conductor helps the air absorb some of those charges from you, while during dry days there is less water in the air and hence the charges build up since they are not absorbed.
  • You are less likely to be shocked when you touch a small metal object because smaller metal objects like a paper clip have less space to accept net charge.

Is force a <br> vector,<br> scalar,<br> both,<br> neither
AysviL [449]

Answer:

Hello Adam Here! :D

Explanation:

A scalar quantity is defined as the physical quantity that has only magnitude, for example, mass and electric charge. On the other hand, a vector quantity is defined as the physical quantity that has both magnitude as well as direction like force and weight. The other way of differentiating these two quantities is by using a notation.

OH YEAH! XD
