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.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba
