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?

2.866 x 10^8 J

Explanation:

Thermal conductivity, K = 0.040 W/m^2 k

Area of the wall, A = 470 m^2

Thickness, d = 17 cm = 0.17 m

difference in temperature, ΔT = 30° C

The rate of heat flow is H.

Time, t = 1 day = 1 x 24 x 60 x 60 second = 86400 second

By use of formula of heat flow

H = 2.866 x 10^8 J

prolly a beacuse the momentuem the car has increases while going down hill

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
