CIRCUIT Switched network has the conventional telephone system as the most common example.
Circuit switching<span> is a method of implementing a telecommunication network </span><span>in which two network nodes </span><span>establish a dedicated communications channel or circuit </span><span>through the network before the nodes may communicate. The circuit guarantees the full bandwidth of the channel and remains connected for the duration of the communication session by functioning as though the nodes were physically connected like an electrical circuit.</span>
In a conventional telephone system, when a call is made from one telephone to another, switches within the the telephone exchanges create a continuous wire circuit between the two units for as long as the call lasts.
I = Δmv = mv₁ - mv₂
m = 0.25 kg
v₁ = 5 m/s
v₂ = - 30 m/s
Displacement is just the distance between the start point and the end point. Just subtract the numbers.
Answer:
The force by which a substance (magnet) attracts a body(metals) towards it is called magnetic force
For speed you can differentiate the equation, for acceleration you can again differentiate the equation .
at t=0 the particle is slowing down , when you get equation for velocity put t=0 then only -1 is left
