... which is moving in the same direction with a speed of 0.40 m/s. If the faster ball slows down to a speed of 0.65 m/s, then what is the speed of the second ball? PSYW 56. A 0.050-kg billiard ball moving at 1.5 m/s strikes a second 0.050-kg billiard ball which is at rest on the table. If the first bal ...

Superfluid Helium 3: Link between Condensed Matter Physics and
... As demonstrated by Bardeen, Cooper and Schrieffer (BCS) in 19576 the key to the theory of superconductivity is the formation of “Cooper pairs”, i.e. pairs of electrons with opposite momentum k and spin projection σ: (k ↑, −k ↓). In the case of conventional superconductors the Cooper pairs are struct ...

Geometry and Material Effects in Casimir Physics
... Neutral objects exert a force on one another through electromagnetic fields even if they do not possess permanent multipole moments. Materials that couple to the electromagnetic field alter the spectrum of the field’s quantum and thermal fluctuations. The resulting change in energy depends on the re ...

... A 0.40 kg block is pushed up against a spring (with spring constant 270 N/m ) on a frictionless surface so that the spring is compressed 0.20 m. When the block is released, it slides across the surface and collides with the 0.60 kg bob of a pendulum. The bob is made of clay and the block sticks to i ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
