Homes are often insulated with fiberglass insulation in their walls and ceiling. the thermal conductivity of fiberglass is 0.040 w/(m? k).suppose that the total surface area of the walls and roof of a windowless house is 470m2 and that the thickness of the insulation is 17cm .at what rate does heat leave the house on a day when the outside temperature is 30 ? c colder than the inside temperature?

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 × 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.
