Answer:
32 turns
Explanation:
From the expression for the induced emf,
E = (N)(B)(A) w
E = emf = 24 V
N = number of turns = ?
B = magnetic field strength = 0.10 T
A = Cross sectional Area of the loop = 100 cm² = 0.01 m²
w = Angular speed = (2πf) = (2π × 120) = 754.3 rad/s
24 = N (0.1)(0.01)(754.3)
N = (24/0.7543)
N = 31.8 ≈ 32 turns.

Answer:
1.30
Explanation:
To calculate the critical angle we have ti use the formula:

where theta_c is the critical angle, n1 is the index of refraction of the material where the light is totally reflected, and n2 is the refractive index of the other material.
By taking n_2 and replacing we obtain:
