Consider the carbon dioxide gas, co2 (m = 44g/mol), at a temperature of 300k.
[note: use ms excel or a similar program].
a. for this gas, prepare a graph of f (v) (maxwell's velocity distribution)
boltzmann) vs v (speed). *** explain how you did the graph in excel***
b. calculate the quotient f (200.0 ms-1) /f(10.0 ms-1). what is the physical meaning of this quotient?
how would this quotient change if the temperature decreases?
c. calculate the fraction of molecules traveling at speeds between 200m/s and 250m/s. for this one
calculation, approximate the integral numerically, first with a single rectangle and then with two
rectangles, so you can calculate the height of each rectangle at the midpoint of your base.

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .
