An amusement park ride consists of a large vertical cylinder that spins about its axis fast enough that a person inside is stuck to the wall and does not slide down when the floor drops away. the acceleration of gravity is 9.8 m/s 2 . given g = 9.8 m/s 2 , the coefficient µ = 0.521 of static friction between a person and the wall, and the radius of the cylinder r = 4.4 m. for simplicity, neglect the person’s depth and assume he or she is just a physical point on the wall. the person’s speed is v = 2πr t where t is the rotation period of the cylinder (the time to complete a full circle). find the maximum rotation period t of the cylinder which would prevent a 40 kg person from falling down. answer in units of s.

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
