Light is incident on a piece of glass in air at an angle of 33 degrees from the normal. if the index of refraction of the glass is 1.5, what is the angle in degrees that the refracted ray makes with the normal?

What are the factors that affect the resistance of a wire?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

What is a neurotransmitter involved in mood reward, addiction, and motor behaviors?
