Energy? Not quite sure what you are getting at. I was thinking Ui + Ki = Uf + Kf where Ki is 0.

Alpha Decay and Total Kinetic Energy
Since we are looking for K total, I summed the given kinetic energy for lead and the typical kinetic energy of an alpha particle: 0.12 + 5 = 5.12 MeV. My answer is definitely wrong, but I don't how I should approach the problem.

Given RMS Speed, Find Temperature
I tried the kinetic radius, which also didn't work. Is this a plausible temperature for air? Yes or No No was the correct answer.

Given RMS Speed, Find Temperature
In terms of what? I'd believe that since it is just above the freezing point of air, the molecules will move slower and be more compacted.

No, I don't know the value I should get. But in the next part, the correct answer is that this is not a plausible temperature for air.

Given the Volume, Find the Number of Atoms
Yes we have, but I don't think the professor went into detail. But when using the equation, I get the correct answer. Thanks.

No, it should be a cold temperature since it takes them 3 whole seconds to travel such a such distance.
