Thermopane window is constructed, using two layers of glass 4.0 mm thick, separated by an air space of 5.0 mm.
if the temperature difference is 20° c from the inside of the house to the outside air, what is the rate of heat flow through this window?
(thermal conductivity for glass is 0.84 j/s⋅m⋅°c and for air 0.023 4 j/s⋅m⋅°c.)

Tsunamis are fast-moving waves often generated by underwater earthquakes. in the deep ocean their amplitude is barely noticeable, but upon reaching shore they can rise to an astonishing height of a six-story building. one tsunami generated off the aleutian islands in alaska, had a wavelength of 897km and traveled a distance of 3280km in 4.18h. (a) what was the speed (in m/s) of the wave? find the waves (b) frequency and (c) period.
