1. What does Lenz's Law give?
Answer - The law known as Lenz's law is named after Emil Lenz and relies on the principles of conservation of energy and Newton's third law. Lenz's law is the most practical way to establish the direction of the induced current. When the induced electromotive force has different polarities, it causes a current to flow. This current creates a magnetic field that works against the change in magnetic flux through the loop. This ensures that the original flux is maintained through the loop when current flows through it.

6. 5 boys and 6 girls are arranged in all possible ways. Let X denote the number of linear arrangements in which no two boys sit together and Y denote the number of linear arrangements in which no two girls sit together. If Z denote the number of ways of arranging all of them around a circular table such that no two boys sit together, then X: Y: Z =
