Assume that an escape velocity is 50 m/s for an asteroid X but we also have asteroid y that has twice the radius and twice the mass as compared to asteroid X now determine how would you compare the escape velocity of asteroid Y as compare to the escape velocity of asteroid X?
Hydrogen fluoride is a highly reactive gas. It has many industrial uses, but the most familiar property of HF is its ability to react with glass. As a result, HF is used to etch glass and frost the inner surfaces of light bulbs.
This procedure is potentially very lucrative because, after an initial extraction of energy from the groin, no fossil fuels would be required to keep the device running indefinitely. Would you invest in this idea? State your conclusion clearly and..
When a 8.37-g mixture of methane, CH4, and ethane, C2H6, is burned in oxygen at constant pressure, 445.8 kJ of heat is liberated. What is the percentage by mass of CH4 in the mixture
At what pressure does the mean free path of argon at 25C become comparable to the size of 1dm^3 vessel that contains it? take ?=.36nm^2
