Noether theorem (Noether):
A theorem which revels that symmetries are what gives increase to conserved quantities. For example, translational symmetry (the fact that the laws of physics work the similar in all places) gives increase to conservation of momentum, as position & momentum are complementary. In addition, conservation of energy is mention by time symmetry, & conservation of angular momentum is mentioned by isotropy.
What is a zone plate? How is it constructed? Show that a zone plate behaves like a convex lens. Deduce the expression for its focal length
A 2.1 kg block slides along a horizontal surface with a coefficient of kinetic friction μ k = 0.31. The block has a speed v = 1.4 m/s when it strikes a massless spring head-on.
A 10 kg block slides down a smooth inclined surface as shown in Figure 1. Determine the terminal velocity of the block if the 0.1 mm gap between the block and the surface contains
