A light beam containing red and violet wavelengths is incident on a slab of quartz at an angle of incidence of 65.3°. The index of refraction of quartz is 1.455 at 660 nm (red light), and its index of refraction is 1.468 at 410 nm (violet light). Find the dispersion of the slab, which is defined as the difference in the angles of refraction for the two wavelengths.
Just before the collision and in kilometers per hour, what was the speed of the rocket piece relative to the satellite if both were in circular orbits and the collision was (a) head-on and (b) along perpendicular paths.

What must the charge (sign and magnitude) of a 1.46 g particle be for it to remain stationary while placed in a downward-directed electric field of magnitude 690.
One of Einstein's postulates says that nothing travels faster than the speed of light in a vacuum, c, what limit does this place on the numerical value for n
A child slides across a floor in a pair of rubber-soled shoes. Thefriction force acting on each foot is 20.0 N. The footprint area ofeach shoe sole is 14 cm2, and the thickness of eachsole is 5 mm. Find the horizontal distance by which the upper a..
The potential at location A is 481 V. A positively charged particle is released there from rest and arrives at location B with a speed vB. The potential at location C is 878 V, and when released from rest from this spot, the particle arrives at B wit..
