Homework Statement
A simple hydrostatic system is such that PV^k is constant in a reversible adiabatic process, where k > 0 is a given constant. Show that its internal energy has the form
E=\frac{1}{k-1}PV+NF(\frac{PV^k}{N^k}
where f is an arbitrary function. Hint: PV^k must be a function of...
Homework Statement
what does the expression \delta_{ii} mean?
Homework Equations
\delta_{ij}=1 if i = j and 0 otherwise
The Attempt at a Solution
What I'm not sure about is if both indices are in the subscript does this mean i can only use it on a term with a subscript or can it also act on...
Homework Statement
show, using the propagating wave y = Ae^[i(wt - kx)] that the average power transmitted across any point on the string in a complete full cycle is given by P = vE (P and E are both vectors). v is the phase velocity and E the total average energy density per cycle. also show...
Temperature in a nuclear spin 1/2 system??
Homework Statement
A solid at temperature T contains 10^20 protons which have a spin I = 1/2 and a nuclear g-factor of 5.59. Calculate the temperature such that 75% of the protons have their magnetic dipole moment aligned parallel to the applied...
