Hint 1. understanding mean square velocityopened hint the mean square velocity is given by (v2)avg=(∑v2)/n, where the sum is taken over all the molecules in the gas and n is the total number of molecules. if you take the central speed value of each bin as an estimate of the speed of all the molecules in that bin, this equation reduces to (v2)avg=∑binsnbinv2n, where the sum is now over the number of discrete bins and nbin is the number of molecules (or equivalently the percentage of molecules) in a particular bin.

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.

m=-16

step-by-step explanation:

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
