Aglass plate whose index of refraction is 1.57 is immersed in a liquid. the surface of the glass is inclined at an angle of 54° with the vertical. a horizontal ray in the glass is incident on the interface. the liquid is an oil whose index of refraction is 1.40. the incident horizontal ray refracts at the interface. what is the angle that the refracted ray, in the oil, makes with the horizontal?

An electric power distributor charges residential customers $0.10 per kilowatt-hour (kwh). the company advertises that "green power" is available in 150 kwh blocks for an additional $4 per month. (green power is generated from solar, wind power, and methane sources.) if a certain customer uses an average of 391 kwh per month and commits to one monthly 150 kwh block of green power, what is her annual power bill

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
