Synchronous communications satellites are placed in a circular orbit that is 3.59* 10^7 m above the surface of the earth. What is the gravitational field strength at this height? (0.223 m/s^2) Gravitational field strength = g = GM/r^2 (the force it would exert per kilogram.)

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
