We can approximate an electron moving in a nanowire as a one-dimensional in?nite square-well potential. Let the wire be 2 micrometers long. The nanowire is cooled to a temperature of 13K and we assume the electrons average kinetic energy is that of gas molecules at this temperature (3 2 kT).
a) What are the three lowest energy levels of the electrons?
b) What is the approximate quantum number of electrons moving in the wire?
A 74 kg diver steps off a 14 m tower and drops from rest straight down into the water. If he comes to rest 4.4 m beneath the surface, identify the average resistance force exerted on him by the water.
A cosmic-ray proton in interstellar space has an energy of 10 MeV and executes a circular orbit having a radius equal to that of Mercury's orbit around Sun (5.80 × 1010 m). What is the magnetic field in that region of space.
A wrecking yard inventor wants to pick up cars by charging a 0.400 m diameter ball and inducing an equal and opposite charge on the car. If a car has a 1000 kg mass and the ball is to be able to lift it from a distance of 1.00 m: (a) What minimum ..
A circular coil, with radius of 10 cm, and 25 turns, rotates in a constant magnetic field of strength 2.4 T, If the magnetic field that the coil is in points down the page, which direction does the coil rotate
Certain stars at the end of their lives are thought to collapse combining their protons and electrons together to form a neutron star. Such a star could be thought of as a giant atomic nucleus.
A tank with vertical walls, 2m wide and 2m long and 2.5 m high, is filled with 4800 litres of water (density 1000 kg/m3) and 3200 litres of light oil (density 900 kg/m3). compute the magnitude and location of the resultant force on each of the ver..
