Estimate the speed of a typical long-period comet at perihelion. (Hint: At aphelion, the comet is moving very slowly.)
We study the relationship between the position space wave function and the momentum space wave function in quantum mechanics
The time-independent Schrodinger equation for a free particle moving in one dimension (x) is written as (d^2 Psi(x) / dx^2) + k^2 Psi(x) = 0, where k is a const
The magnitude and direction(with respect to B) of magnetic moment induced by the field.
A physical pendulum consists of a uniform rod of mass M and length L. The pendulum is pivoted at a point that is a distance x from the center of the rod
An electron of mass m is in a circular orbit in the potential U=0.5 k r^2. Using Bohr's quantization rule, find the allowed orbital radii and energy levels.
The earth's radius is 4000 miles, the highest point that the satellite is from the surface of the earth is 800 miles, and the lowest is 200 miles.
A celebrity holds a press conference, which is televised live. A television viewer hears the sound picked up by a microphone directly in front of the celebrity.
An electron is in a strong, static, homogenous magnetic field with magnitude B0 in the z direction. At time t=0, the spin of the electron is in the +z direction
Find the only way to construct a length from the parameters in the Schrodinger equation for the hydrogen atom. Compare with the Bohr radius.
Two charged particles are traveling in circular orbits with the same speed in a region of uniform magnetic field that is directed into the page, as shown.
Assuming the solid behaves like most solids, what is the coefficient of volume expansion?
A result of Kepler's harmonic law is that the mass of a planet (M) with a satellite is directly proportional to the cube of the mean distance.
Calculate the force on a satellite due to drag and the mass of propellant needed to overcome the drag force.
Write down the general solution for the wave function inside the well.
What did the Voyager mission discover about the main rings of Saturn?Pluto cannot be called a jovian planet because.
How two traveling waves of nearly the same frequency can create beats and to interpret the superposition as a "walking" wave
A race car makes two and a half laps around a circular track in 3 mins. What is the car’s average angular speed?
The nodes of a standing wave are points at which the displacement of the wave is zero at all times. Nodes are important for matching boundary conditions
A sinusoidal wave is propagating along a stretched string that lies along the x-axis. The displacement of the string as a function of time is graphed
Assuming that the orbit of the X-ray source is a circle, find the radius of its orbit in kilometers. (This is actually an estimate of the semimajor axis of the
