Homework Statement
Suppose you have 7 atoms with only 6 quanta. If you add 2 quanta to the system, find the change in entropy to the system.
Homework Equations
S = k_B*ln(omega)
Change in S = S_f - S_o

Homework Statement
A 1.1 m, 4 kg chain is wrapped up in a ball. You grab one of the ends of the chain and apply a constant force of 59 N and it begins to unwrap. When you pull your end of the chain 3.9 m, the chain is completely loose.
a) Find the change in energy of the system, before...
Homework Statement
A small material has quantum oscillator energy levels 2E-23 J apart. Suppose the material has a total energy of 34E-23 J and contains 5 atoms. Find the entropy of the material.
Homework Equations
Entropy = (Boltzmann's constant)*ln(multiplicity)
Multiplicity = (q +...
Homework Statement
If the temperature underground is 5 degrees Celsius and you'd like to keep the house at 20 degrees Celsius, how much work per joule leakage must be done to maintain the house at that temperature?
Homework Equations
Q/W = 1/(1-(Tc/Th))

Oh... I think I see it. So, the normal force would be (64kg)(g) and the gravitational force would be (59kg)(g), thus the net force is 5*g upwards, which implies that this is what the centripetal force is equal to?
Is my reasoning correct?
I made a mistake, the problem stated that you measured yourself on a scale on the very bottom of the circle to be 64 kg. I don't see the other force...
Homework Statement
Suppose that you're on a circular ferris wheel with a radius of 22 m. You know that your mass is 64 kg on the very bottom part of the ferris wheel, even though your actual mass is 58 kg. How long does it take for the ferris wheel to go one revolution?
