A semiconductor diode is used in rectifying alternating current into direct current mainly because it

if ∆x is the uncertainty in the measurement of the position of a particle along the x-axis and ∆P_x is the uncertainty in the measurement of the linear momentum along the x-axis, then the uncertainty principle relation is given as

If ∆x is the uncertainty in the measurement of the position of a particle along the x-axis and ∆P_a is the uncertainty in the measurement of the linear momentum along the x-axis, then the uncertainty principle relation is given as

The diagram above shows the velocity-time graph of a vehicle. Its acceleration and retardation respectively are
