Let the radius of the circular segment be 105 m, the mass of the car 2011 kg, and the coefficient of the static friction between the road and the tire 0.7. find the magnitude of the normal force n which the road exerts on the car at the optimal speed (the speed at which the frictional force is zero) of 85 km/h. the acceleration due to gravity is 9.8 m/s 2 . answer in units of n.

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?
