Can the atoms in a liquid helium : Can the atoms in a liquid helium at 4K (interatomic distance about 0.1 nanometer) be adequately represented by nonspreading wave packets, so that their motion can be described classically.

Which technique is used to determine magnetic structure : Diffraction studies involving X-rays, electrons or neutrons give information about the crystallographic properties of solids. Compare these three techniques with reference to particle energies and types of information that can be obtained. Which ..

What is the change in entropy for the entire mixed system : An air parcel occupied by an ideal gas (T1 = 255 K, V1 = 1500m3, m1 = 1680 kg) collides and mixes with a second air parcel occupied by a second ideal gas (T2 = 280 K, V2 = 1200 m3, m2 = 1392 kg). Assuming the specific heat capacities of the gases ..

The ground state of the realistic helium atom : The ground state of the realistic helium atom is of course nondegenerate. However, consider a hypothetical helium atom in which the two electrons are replaced by two identical spin-one particles of negative charge. Neglect spin-dependent forces. F..

Estimate the electric field needed to pull an electron : Estimate the electric field needed to pull an electron out of an atom in a time comparable to that for the electron to go around the nucleus.

Different isotopes through paths with different radii : By curving different isotopes through paths with different radii, a mass spectrometer can be used to purify a sample of mixed uranium-235 and uranium-238 isotopes. Assume that B = 5.00*10^-3 T, V = 55.0 V, and that each uranium isotope has a 5+ io..

What is the force between the two alpha particles : The nucleus of 8Be, which consists of 4 protons and 4 neutrons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of 2 protons and 2 neutrons). What is the force between the two alpha particles when th..

Assume that the bug is moving in the direction of rotation : A cockroach crawls with a constant speed on a phonograph turntable that is rotating with angular velocity ?. If the bug moves at constant speed away from the center of the turntable draw all forces acting on the bug (in the bug's frame).(b) Now sa..

What direction is the coriolis force : On the salt flats of Bonnevile, Utah (latitude ?41?^o N) the British auto racer John Cobb in 1947 became the first man to travel at a speed of 400 mph on land. If he was headed due north at this speed, find the ratio of the magnitude of the Coriolis ..
