1. The problem statement, all variables and given/known data When it comes to evaluating integrals, there are two ways you can do it. First, you know that the integration of a function is the area under a curve, as shown in the left hand diagram. However, if you are looking over a narrow range along the x-axis, you can make an estimation for the area as shown on the right: Use the integral estimation represented on the right to calculate the fraction of Krypton atoms moving between 200 m/s to 210 m/s at 30 °C from the Maxwell-Boltzmann distribution. Hint: ∆x=10 m/s, now how do you get ∆y? 2. Relevant equations [itex]/[/itex]y(x)dx = [itex]\sum[/itex]y(n∆x)∆x Total area of curve = 1 3. The attempt at a solution I tried plugging in some numbers but it wasnt working too well...any advice?
