A10 uf capacitpr is connected to a 12 v battery till its fully charged. it is then disconnected and to an uncharged 20 uf capacitor. find energy stored on 20 uf capaciotr when it has reached an electro static equilibrium

In a series circuit the __ is the same at every point

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

Look at the electroscope, describe how you can cause the two leaves at the bottom to repel each other and stay that way
