Which of the two parts of an optical fibre has a higher value of refractive index?

Which one of the isomeric dichlorobenzens has the highest melting point and why?

A cell of emf 1.5 V and of internal resistance 0.1Omega when connected with a resitor and an ammeter of negligible resistance in series , the ammeter shows a 2.0 A steady current . Find (ii) the power consumed in the resistor .

Which out of n-pentane and neopentane has higher boiling point and why ?

A semiconductor -resistor is connected in parallel with a variable resistance.This combination is joined in series with an electric cell and a milliammeter . If the temperature increases,how would you keep the milliammeter reading to a constant value? Justify your answer.

Statement : I A galvanometer of resistance G is converted to an ammeter by increasing its range n times. The resistance of the ammeter is (G)/(n) . Statement : II A shunt of resistance (G)/(n-1) has to be connected in parallel with a galvanometer in order to increase its range n times.
