You are standing 2 feet away from your friend, you are not safely socially distancing. To get to a safe
distance, you will need to stand 3 times farther apart (6 ft apart). Not only are you safer, but the force of
gravity between you has changed, what has happened to this force of attraction?

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
