Aplane is descending towards a runway in new york. the plane is flying at an altitude of 8 miles and is 175 miles from the runway, as measured from the ground. what angle will the plane's path make with the runway? round your answer to the nearest hundredth.

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
