What is the refraction index of a medium? -the ratio of the velocity of light in the medium over the velocity of light in a vaccum-the ratio of the velocity of light ina vacuum over a velocity of light in the medium-the ratio of the angle of incidence over the angle of refraction-the ration of the angle of refraction over the angle of incidence

Write the function getkthdigit(n, k) that takes a possibly-negative int n and a non-negative int k, and returns the kth digit of n, starting from 0, counting from the right

Most short-period comets do not have randomly oriented orbits because

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
