Answer:
2.30714 W
-16.38071 W
Explanation:
k = Heat conduction coefficient = 0.8 W/(m·°C)
A = Area = 2907 cm²
l = Thickness = 5.6 mm
= Outside temperature
= Inside temperature
Rate of heat transfer is given by
The rate of energy transfer is 2.30714 W
The rate of energy transfer is -16.38071 W
Answer: hertz
Explanation:
Wavelength is also measured in metres ( ) - it is a length after all. The frequency ( ) of a wave is the number of waves passing a point in a certain time. We normally use a time of one second, so this gives frequency the unit hertz ( ), since one hertz is equal to one wave per second.
D. Because the moons shadow during a total lunar eclipse is tinnier than the earth.
3) Earth is about 150 million km from the Sun, and the apparent brightness of the Sun in our sky is about 1,300 watts per square meter. Determine the apparent brightness we would measure for the Sun if we were located five times Earth's distance from the Sun. Answer: The Sun would appear 1/25 times as bright.
