Answer: T = -0.213°c
Heat flow = 38.2 w/m²
Explanation:
given data:
Wood = 0.031m thick
Styrofoam = 0.023m thick
Wood = k ( 0.080W/m.k)
Styrofoam = k (0.010W/m.k)
Temperature of wood = -15°c
Temperature of styrofoam = 19°c
(a) heat flow in wood and styrofoam must be equal
KAdT/ L = KAdT/ L
0.080 * A * ( T - ( -15) ) / 0.031 = 0.010 * A * ( T - ( 19°c) ) / 0.023
T = -0.213°c
(b) heat flow
H = KAdT / L
H = 0.080 * A * ( -0.213°c - ( -15°c) ) / 0.031
= 38.2 w/m²
Read the paragraph multiple times and find the main ideas and supporting details. Find what it is mostly about and compare the information you have to the statements and select the one most like yours. This is the best I can do without seeing any of the choices and the paragraph. Hope this helps! :)
Answer:
Another danger that comes with intrapreneurs is the lack of patience from other people in the office. To people who have worked their whole lives in one company, they might expect to see instant results from somebody who has waltzed in and promised big things.
Answer:
Infrared Wavelength
Explanation:
It is because the most long range wavelength i n this case will be the infrared wavelength that has a heating effect on bodies when exposed for a longer period of times. Similarly, the visible wavelength of light is also involved. The defective parts in the fireplace will allow the escape of these infrared wavelength radiations. This heating effect can cause fire near the fire place where the defective fireplace is placed without modifications.
The radius of the new moons orbit is R= 7.715 x 10^7 m
The orbital period of the moon is T= 14.48 hr
