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?
Calculate the voltage, current, and power across the two resistors for every second of run 1 in the RC circuit.
The RC Circuit:
The settings of the circuit:
The Graph. The capacitor is charged until it reaches 5.0 V and then discharged until it reaches 1.0 V. This...
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...
A 3.00-kg block of silicon at 60.0°C is immersed in 6.00 kg of mercury at 20.0°C. What is the entropy increase of this system as it moves to equilibrium? The specific heat of silicon is 0.17 cal/(g·K) and the specific heat of mercury is 0.033 cal/(g·K).
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?
A gas consisting of 15,200 molecules, each of mass 2.00 x 10-26 kg, has the following distribution of speeds, which crudely mimics the Maxwell distribution:
Number of Molecules - Speed (m/s)
1600 - 220
4100 - 440...
A Carnot cycle, shown in Fig. 20-7, has the following conditions: Va = 7.5 L, Vb = 15 L, TH = 470°C, and TL = 260°C. The gas used in the cycle is 0.50 mil of a diatomic gas, y = 1.4. Calculate (a) the pressures at a and b; (b) the volumes at c and d. (The rest of the...
