What is Roche limit
Roche limit: The position about a massive body where the tidal forces due to the gravity of the primary equivalent or exceed the surface gravity of a specified satellite. Within the Roche limit, such a satellite will be interrupted by tides.
Reflection law: For a wave-front intersecting a reflecting surface, the angle of incidence is equivalent to the angle of reflection, in the similar plane stated by the ray of incidence and the normal.
Causality principle: The principle which cause must always precede effect. More properly, when an event A ("the cause") somehow persuades an event B ("the effect") that take
NUCLEAR PHYSICS (PHY555) HOMEWORK #1 1. Calculate the luminosity for a beam of protons of 1 µA colliding with a stationary liquid hydrogen target 30 cm long. Compare this to a typical colliding beam luminosity of ∼1034 cm-2
State the law of Lamberts Cosine? Describe briefly?
Noether theorem (Noether): A theorem that explains that symmetries are what gives rise to conserved quantities. For example, the translational symmetry (that is the fact that the laws of physics work the same in all positions) gives r
Woodward-Hoffmann rules: The rules leading the formation of products throughout certain kinds of organic reactions.
Gauss' law (K.F. Gauss): The electric flux via a closed surface is proportional to the arithmetical sum of electric charges contained in that closed surface; in its differential form, div E = rho,
What do you mean by the term wave fronts? Explain in short.
Explain how asteroids are formed? Describe.
Steradian: sr: The supplementary SI unit of solid angle stated as the solid central angle of a sphere which encloses a surface on the sphere equivalent to the square of the sphere's radius.
