England skipper Joe Root is excited to bat ____ number three in the Ashes cricket series

Transistors were used in ____ of Computers.

In a test by Murray loop for ground fault on 600 m of cable having a resistance of 1.5 Ω/km, the faulty cable is looped with a sound cable of the same length and area of cross section. If the ratio of the other two arms of the testing network at balance is 3 : 1, find the distance of the fault from the testing end of cables.

Where,
d is distance in m
Q is value of variable resistor in ohm
P is variable resistance in ohm
Here Q/P = 1/3 is given,
d = Q/(P + Q)*Loop length
= 1/4*(2*600)
= 300 m

Vikram Seth is associated with which of the following fields?

If the velocity of electromagnetic wave in free space is 3 × 10⁸ m/s, then the velocity in a medium with εr of 4.5 and μr of 2 would be

Speed of EM wave in medium = C/√(εr*μr)
= (300000000)/√9
= 300000000/3
= 100000000
= 1*10⁸ m/s
