True or false electronic machines with no moving parts experience friction and get hot because electricity is moving through the wires

The answer is TRUE. When electrons are passing through a wire, thy experiences some resistance in the wire. This is analogous to friction. Different types of wires have different types of resistance including the width of the wires. It is due to this resistance that some of the energy in the electric power is lost and dissipated as heat energy. This is why electronics get hot when used for long periods.  

step-by-step explanation:

we are given

we have to simplify it

firstly, we will factor it

now, we can cancel like terms

now, we can combine it

so, we get

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
