Thanks, I was looking at the circuit wrong (I thought the charge was coming out the top and hitting the resistor after the capacitor).
Is there a way to calculate the voltage of the capacitor as it is discharging from 5V?
Homework Statement
Calculate the voltage, current, and power across the two resistors for every second of run 1 in the RC circuit.

I'll fix my units. The answer for question (a) is correct according to the book solutions.
EDIT: I misread the answer, it is 0.2 ps. So there is no problem (besides my units).

Two positive charges +Q are affixed rigidly to the x-axis, one at x = +d and the other at x = -d. A third charge +q of mass m, which is constrained to move only along the x-axis, is displaced from the origin by a small distance s << d and then released from rest. (a) Show...
But if 20°C (293.15 K) is the initial temperature and the final temperature is Ti + ΔT = 20°C + 25°C = 293.15 K + 298.15 K = 591.3 K, and ΔT is Tf - Ti, then isn't ΔT = 591.3 K - 293.15 K = 298.15 K? What am I missing? Don't they give the change in temp right away? :(
I believe so. There is 1 significant figure (the 1 liter volume), so the answer I would have is 2x10-4.
But the issue isn't the sig. figs. (at least I don't think), it's the exponent. My answer has 2x10-4, while the closest answer is 2x10-5. I've gone over my calculations and I believe I have...

The coefficient of volume expansion of olive oil is 0.68 × 10-3 K-1. A 1-liter glass beaker is
filled to the brim with olive oil at room temperature. The beaker is placed on a range and the
temperature of the oil and beaker increases by 25 C°. As a result, 0.0167 liters of...

I did what you said: I squared the velocities, then I calculated the weighted average (same way as I did above), and then took the square root of the weighted average. I ended up getting 82914.03 m/s, which is close to the answer I originally got but not the correct answer.
What am I missing?
