The Johnstown Inclined Plane in Pennsylvania is one of the longest and steepest hoists in the world. The railway cars travel a distance of 896.5 feet at an angle of approximately 35.4°, rising to a height of 1693.5 feet above sea level. (see figure in the website). (Round your answers to two decimal places.)
(a) Find the vertical rise of the inclined plane. (in feet)
(b) Find the elevation of the lower end of the inclined plane.(in feet)
(c)The cars move up the mountain at a rate of 300 feet per minute. Find the rate at which they rise vertically. (in ft/min)

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?
