A meteor melts when it enters the Earth’s atmosphere. Assuming that the meteor is primarily made of iron and that its initial temperature was −125°C outside of Earth’s atmosphere, calculate the minimum speed it must have had before it entered Earth’s atmosphere. (The specific heat, the melting point, and the latent heat of fusion for iron are 450 J/kg.°C, 1808°C, and 2.89 x 10^5 J/kg , respectively.)

The sun produces energy by nuclear fusion reactions, in which matter is converted into energy. By measuring the amount of energy we receive from the sun, we know that it is producing energy at a rate of 3.8 * 1026 W. (a) How many kilograms of matter does the sun lose each second? Approximately how many tons of matter is this (1 ton = 2000 lb)? (b) At this rate, how long would it take the sun to use up all its mass?
