A plenet moving along an elliptical orbit is closest to the sun at a distance r_(1) and farthest away at a distance of r_(2) . If v_(1) and v_(2) are the linear velocities at these points respectively, then the ratio (v_(1))/(v_(2)) is

Write the reletion between resistance R of the filament of a bulb, its power and a constant voltage V applied across it.

Statement I : In the circuit in Fig. 7.46 , both cells are ideal and of fixed emf, the resistor R_(1) has fixed resistance and the resistance of resistor R_(2) can be varied ( but R_(2) is always non zero). Then the electric power delivered to the resistor of resistance R_(1) is independent of the value of resistance R_(2) . Statement II: If potential difference across a fixed resistance is unchanged , the poweer delivered to the resistor remains constant.
