266617 According to Faraday's law of electromagentic induction.

1 The direction of induced current is such that it opposes the cause producing it

2 The magnitude of induced e.m.f. produced in a coil is directly proportional to the rate of change of magnetic flux

3 The direction of induced e.m.f. is such that is fevar the cause producing it

4 None of the above

Explanation:

b
$e = \frac{- N d ϕ}{dt}$

266618 Refractive indices of water and glass are $\frac{4}{3}$ and $\frac{3}{2}$ respecitvely. A ray of light travelling in water is incident on the water glass interface at $30^{\circ}$ . The angle of refraction is:

1

\sin^{- 1} (8 / 18)

2

\sin^{- 1} (4 / 3)

3

\sin^{- 1} (3 / 2)

4

\sin^{- 1} (1818)

Explanation:

a
Here, $_{a} μ_{w} = \frac{4}{3},_{a} g_{g} = \frac{2}{3}$
$_{w} μ_{g} = \frac{_{a} μ_{a}}{_{a} μ_{w}} = \frac{3 / 2}{4 / 3} = \frac{9}{8}$

266619 When a P-N junction is forward biased, the flow of current across the junction is mainly due to:

1 Drift of charges

2 Diffusion of charges

3 Both drift and diffusion of charges

4 Depends on the nature of the material.
