Answer:
1.318 * 10^(-2) m
Explanation:
Parameters given:
Frequency, f = 22.75 * 10^9 Hz
Velocity, v = 2.9979 * 10^8 m/s
Wavelength is given as:
Wavelength = v/f
Wavelength = (2.9979 * 10^8) / (22.75 * 10^9)
Wavelength = 0.01318 m = 1.318 * 10^(-2) m
Power in a wire where current is flowing can be calculated from the product of the square of the current and the resistance. Resistance is equal to the product of resistivity and length divided by the area of the wire. We do as follows:
Resistance = 2.44 × 10-8 ( 0.11) / (π)(0.0009)^2 = 1.055x10^-3 <span>Ω
P = I^2R = .170^2 (</span>1.055x10^-3 ) = 3.048x10^-5 W

Answer:
θ = 41.8º
Explanation:
This is an internal total reflection exercise, the equation that describes this process is
sin θ = n₂ / n₁
where n₂ is the index of the incident medium and n₁ the other medium must be met n₁> n₂
θ = sin⁻¹ n₂ / n₁
let's calculate
θ = sin⁻¹ (1.00 / 1.50)
θ = 41.8º
