Question

Define lenzes law and how it supports law of conservation.Of energy

Answer 1

Answer:

Lenz's Law states that, when you induce a current in a wire via a changing magnetic field, the current flows through the wire in such a direction so that its magnetic field opposes the change that produced the current.

So, what happens when you induce a current by, say, moving a wire through a magnetic field, is that you're converting mechanical energy (the energy of the wire's motion) into electrical energy (the energy carried by the induced current).

Lenz's Law ensures that the mechanical energy of the wire is reduced by the same amount of energy gained by the current. It does this by exerting a force on the wire opposing the wire's motion. This causes the wire to lose mechanical energy (its motion is impeded); it must do work against the induced magnetic field to generate current.

Answer 2

Answer:

$\mathtt \red{ \xcancel{\int ( \frac { 2 + 3 \cos x } { \sin ^ { 2 } x } ) d x}} \\ \mathtt \red{ \xcancel{\int ( \frac { 2 + 3 \cos x } { \sin ^ { 2 } x } ) d x}} \\ \mathtt \red{ \xcancel{\int ( \frac { 2 + 3 \cos x } { \sin ^ { 2 } x } ) d x}}$
