What happens to the resistance of a wire as its length decreases? a. the resistance decreases. b. the resistance alternates between high and low values. c. the resistance increases. d. the resistance is not affected by a change in wire length.

option (A)

Explanation:

The resistance is defined as the obstruction offered by the material in the path of flow of electrons.

The resistance of a conductor is directly proportional to the length of the conductor and inversely proportional to the area of crossection f the wire.

As the length of the wire decreases, the resistance of the wire also decreases.

Option (A) is correct.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
