Two coils have the same number of circular turns and carry the same current. Each rotates in a magnetic field acting perpendicul

ANEK [815]

Answer:

4.14 cm.

Explanation:

Given,

For Coil 1

radius of coil, r₁ = 5.6 cm

Magnetic field, B₁ = 0.24 T

For Coil 2

radius of coil, r₂ = ?

Magnetic field, B₂ = 0.44 T

Using formula of maximum torque

$\tau_{max}= NIAB$

Since both the coil experience same maximum torques

now,

$NIA_1B_1 = NIA_2B_2$

$A_1B_1 = A_2B_2$

$r_1^2 B_1 = r_2^2 B_2$

$5.6^2\times 0.24= r_2^2\times 0.44$

$r_2 = 4.14\ cm$

Radius of the coil 2 is equal to 4.14 cm.

What is the value of the angle of refraction of light from a crown glass slab when the angle of incidence is 50°? The slab has a

Artemon [7]

The angle of refraction is $30.3^{\circ}$

Explanation:

Refraction is a wave phenomenon that occurs when a light wave passes through the interface between two mediums. When this occurs, the speed and the direction of the light wave change.

We can find the final direction of the refracted light in this problem by applying Snell's law:

$n_i sin \theta_i = n_r sin \theta_r$
