The tambora volcano on the island of sum sea, Indonesia has been known to throw ash into the air with speed of 625 m/s during an eruption. How high could this volcanic plume have risen? On Venus, where the acceleration due to gravity is slightly less than on earth, would this volcanic plume rise higher or not as high as it does on earth?

If a sphere and a cure have the same mass and are propelled up a ramp with the same force, which would travel father up the ramp? explain.

Specific heat refers to the amount of heat required to change 1 gram of a substance by degree(s) celsius

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 =
