Is an iron rod a good conductor of heat and electricity

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

1= 26.17

2= 1.17

3=30.86

4=5.86
