Consider the growth of a 20-nm-diameter silicon nanowire onto a silicon wafer. the temperature of the wafer surface is maintained at 2400 k. assume the thermal conductivity of the silicon nanowire is 20 wm-1k-1 and all its surfaces including the tip are subjected to convection heat transfer with the coefficient h = 1×105 wm-2k-1 and t∞ = 8000 k. when the nanowire grows to l = 300 nm, what is the temperature of the nanowire tip (t (x =

which statements describe the image? check all that apply. the wood is releasing argon gas. this information is useful for dating ancient rock. the process works only with organic matter. the element has a half-life of 5,730 years. this shows the half-life of carbon-19.

For most stars, what does a higher temperature tend to to with? a lower luminosity a higher luminositya red color none of the above
