State the principle of conservation of energy.

Asseration:Lenz's law violates the principle of conservation of energy. Reason: Induced e.m.f. opposes always the change in magnetic flux responsible for its production.

Asseration:Lenz's law violates the principle of conservation of energy. Reason: Induced e.m.f. opposes always the change in magnetic flux responsible for its production.

Assertion : In interference and diffraction, light energy is redistributed. Reason : There is no gain or loss of energy, which is consistent with the principle of conservation of energy.

STATEMENT-1: Lenz's law is based on the principle of conservation of energy. Because STATEMENT-2: The magnitude of the induced emf is directly proportional to the rate of change of the magnetic flux.

(a) State Lanz's law. Give one example to illustrate this law. "The Lenz's law is a consequence of the principle of conservation of energy." Justify this statement. (b) Deduce a expression for the mutual inductance of two long coaxial solenoids but having different radii and different number of turns.

Use the definition of linear pometum form the previous qestion. Can we state the principle of conservation of linear pomentum for a single particle?

A 5H inductor is placed in series with a 10Omega resistor. An emf of 5V being suddenly applied to the combination. Using these values prove the principle of conservation of energy, for time equal to the time constant.

Assertion: Energy can neither be created nor destroyed. Reason: The principle of conservation of energy cannot be proved.

State the principle of floatation.

Define the law of conservation of energy.
