Oh, it does say particle energy flux - I must have missed it out whilst transferring the question. Given this, did I calculate it correctly? So, if electrons have a negative charge and flow to the right, would current flow to the left as my answer is positive? There is a good chance that I'm...

Homework Statement: Consider electron precipitating vertically into an auroral arc of area 1.0 km x 1200 km in the horizontal plane. The energy of the electrons is equal to 5 keV and the electron flux is 8.0 x 10^13 m^-2 s^-1. Determine the total particle energy into the arc, the total current...

Given that they're all on the same branch, I had assumed that they were in series with one another. But with the middle resistor having being on the middle of three branches, it looks parallel. Like I said, I have a feeling it's in series (making the answer 3R). This question is from a past...

Is it because the gas is ideal, and the internal energy of an ideal gas is purely kinetic, so it only considers the heat? I'll admit I'm not sure why it's Cv and not Cp because volume isn't constant, but pressure is. $$\frac{p(V_1-b)}{nR} = T_1$$ $$\frac{p(V_2-b)}{nR} = T_2$$ $$T_2-T_1 =...

"The equation of state of n moles of a gas is p(V-b)=nRT. The molar heat capacities of the gas at constant pressure and constant volume, cp and cv, satisfy cp - cv = R, where R is the gas constant, and γ = cp/cv = 5/3. Find the change in internal energy of one mole of the gas in an isobaric...

I've got a question that requires me to use the Van der Waals equation in the form: p(V-b)=nRT The process is isobaric, the volume changes from 1m3 to 2m3, and there is 1 mole of the unidentified gas. Ultimately, I need to find initial and final values of T. So I rearranged the formula...

Thank you for your help

919... I feel ever so silly, thank you.

Homework Statement "One way to heat a gas is to compress it. A gas at 1.00 atm at 25.0°C is compressed to one tenth of its original volume, and it reaches 40.0 atm pressure. What is its new temperature?" So, I have: P1 = 1 V1 = 1 T1 = 25 P2 = 40 V2 = 0.1 And I'm looking for T2 The question was...
