Question 8 Resistivity of a wire depends on both length and cross-sectional area length cross-sectional area O material

Answer 1

Answer #1

question 4

The area assiciated the pV diagram is work done.

the unit of the work done is joule.

the unit of energy is Joule

Energy is correct option.

Question 8

Resisitivity = (Resistance)(Area)/ length

Hence it depends on both length and cross sectional area
