An extended object is in static equilibrium if the net torque acting on the object is zeroeither the net force acting on the object is zero or the net torque acting on the object is zeroboth the net force acting on the object is zero and the net torque acting on the object is zeroonly the net force acting on the object is zero

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
