d) No effect

Text Solution

Verified by Experts

The correct Answer is:
B
For last 6 m distance tavelled, `S= 6m, u=?, t=0.2 sec, a=g= 9.8 m/s^2, S= ut+ 1/2 at^2, 6=u(0.2)+4.9xx0.04, rarr u=5.8/0.2, 29 m/s`, For distance `x, u=0, v= 29 m/s, as=g= 9.8 m/s^2, :. S_2 = (v^2-u^2)/(2a), = (29^2-0^2)/(2xx9.8)=(29xx29)/19.6, Total distance = 42.5+6=48.5m = 48`

When an AC voltage of 220 V is applied to the capacitor C

In a p-n junction diode, the current I can be expressed as I= I_(0) "exp" ((eV)/(2k_(B)T)-1) where I_(0) is called the reverse saturation current, V is the voltage across the diode and is positive for forward bias and negative for reverse bias, and I is the current through the diode, k_(B) is the Boltzmann constant (8.6 xx 10^(–5) eV//K) and T is the absolute temperature. If for a given diode I_(0) = 5 xx 10^(-12) A and T = 300 K, then (a) What will be the forward current at a forward voltage of 0.6 V?
