Joule's findings resulted in his development of the mechanical theory of heat and Joule's law, which quantitatively describes the rate at which heat energy is produced from electric energy by the resistance in a circuit.
There are no correct descriptive statement on the list you included.
Because you have to have energy to have work.
Actually Welcome to the concept of distance formula.
Distance formula ==>
so applying this we get as,
D = underoot (9)^2 + (-5)^2
==> D = 10.29 units
distance = 10.29 units
