An automotive manufacturer removes the friction linings from the clutch plates of drag race cars following test runs From experience it expects to find the mean wear to be 209.6μm with a standard deviation of 52.5μm Find How many clutch plates out of a large set will be expected to show wear of less than 203μm

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?
