1. A friend suggests to you an alternative to the Virial equation of state: P=(RT/Vm)-(B/Vm2)+(C/Vm3)
a.) Show that this equation is useful by proving that it demonstrates critical behavior.
b.) Find the critical constants Pc, Vm,c, and Tcin terms of B, C and R.
c.) Calculate the...
Homework Statement
A metal ring 4.50cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. These magnets initially produce a magnetic field of 1.12T, but are gradually pulled apart, causing the field to remain...
I think I'm starting to understand. There is some charge q enclosed between the two cylinders. The inner cylinder produces the electric field E=(2kλ)/r, and the total flux is equal to 0, so the outer cylinder must produce a field E=(-2kλ)/r. In that way, the magnitudes of the densities would be...
1. A long coaxial cable consists of an inner cylindrical conductor with radius "a" and an outer coaxial cylinder with inner radius "b" and outer radius "c." The outer cylinder is mounded on insulating supports and has no net charge. The inner cylinder has a positive charge per unit length λ...
What does the spring constant mean for the overall "stiffness" of a spring? Does a larger spring constant mean the spring would be more difficult to compress or stretch? I know that Hooke's law states that F=-kx, and that the units of k are in N/m, I just want to know what the spring constant means.
x=rcos(θ), y=rsin(θ) Do these formulas look familiar? They give the relationship between two coordinate systems in the plane. Evaluate:
|x'r x'θ|
|y'r y'θ|
I know that the x primes are cos(θ) and -rsin(θ), and the y primes are sin(θ) and...
