Aball is projected at an angle of 53. if the initial velocity is the 48 meters/seconds, what is the vertical component of the velocity with which it was launched?

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

4. if you were an astronaut on the moon, what would you experience? what would you see from your perspective?

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 =
