How do charges gain electrical energy? What happens to the electrical energy of the charges as they move through the circuit?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Acarpenter builds an exterior house wall with a layer of wood 2.9 cm thick on the outside and a layer of styrofoam insulation 2.3 cm thick on the inside wall surface. the wood has k=0.080w/(m⋅k), and the styrofoam has k= 0.010 w/(m⋅k). the interior surface temperature is 19.0 ∘c , and the exterior surface temperature is -15.0 ∘c . a.)what is the temperature at the plane where the wood meets the styrofoam? celsius b.)what is the rate of heat flow per square meter through this wall? /m^2

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge
