As your bus rounds a flat curve at constant speed of 17 m/s , a package with mass 0.900 kg , suspended from the luggage compartment of the bus by a string 35.0 cm long, is found to hang at rest relative to the bus, with the string making an angle of 30.0° with the vertical. part a)
what is the radial acceleration of the bus?
express your answer to three significant figures.
part b)
what is the radius of the curve?
express your answer to the nearest meter.

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?
