P9. consider the discussion in section 1.3 of packet switching versus circuit switching in which an example is provided with a 1 mbps link. users are generating data at a rate of 100 kbps when busy, but are busy generating data only with probability . suppose that the 1 mbps link is prop trans t=0 t= trans prop trans t=dtrans prop trans to trans s=2.5⋅108 l=120 bits r=56 kbps. prop trans p=0.1 replaced by a 1 gbps link. a. what is n, the maximum number of users that can be supported simultaneously under circuit switching?

**urgent** roberto plans to use two transformers to reduce a voltage of 120 v to 4 v. he uses a transformer that has 300 coils in the primary winding and 50 coils in the secondary winding. he has four other transformers, as listed in the table. which transformer should roberto use to have an ending voltage of 4 v? a- w b-xc- yd- z

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?
