A beam of light is emitted in a pool of water (nwater = 1.33) from a depth of 83.0 cm . Part A At what minimum distance must it strike the air-water interface, relative to the spot on the surface directly above it, in order that the light does not exit the water?

You are sitting on the beach and wondering about the properties of mechanical waves. describe them in terms of ocean waves.

Which of the following are not typically included in the periodic table? a. atomic mass b. element symbol c. isotopes d. number of electrons

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
