Assume: The small objects are point particles. The system of seven small 2 kg objects is rotating at an angular speed of 9 rad/s. The objects are connected by light, flexible spokes that can be lengthened or shortened.

A) What is the initial angular momentum of the object?

B)What is the new angular speed if the spokes are shortened from 9 m to 6 m ?

C)What is the new angular momentum of the object?

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?
