A prism whose cross section is shaped like an isosceles right triangle is made from a material with index of refraction, n = 1.31. Find the angle θ of the entering/exiting rays that travel parallel to the lower side (in degrees).

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)

As the distance from a magnet increases, what happens to the magnet force?

Properties seen when one one substance changes to another are known as properties
