    But it says that the model is 1/10th of all the linear dimensions, which includes both length and breadth. So if length reduce by 1/10 and breadth does then area reduces by 1/100 right?

    The Answer is B. Current always travels the path with the smallest Resistence. So when the switch is closed all current will flow through that wire and not through the resistor, hence there is no P.D across there. Next, since the current flows through the empty wire, there is an overall drop in...

    40. Remember that an Alpha particle reduces the Atomic number by 2 and the mass by 4. So you will first get 223,87. A beta particle, when emitted, increases the number by 1. so Answer is B

    32. Remember the question states that there are 12 wires in parallel, so try again. 33. Use I^2R is equal to Power, and remember to use the Resistence as 6.5 Ohms. And I is 20V/(6.5+1.5). Hoot hoot brotheraxe. Ask more.
