If the magnetic vector potential A = -ρ24 az Wb/m, what is the total magnetic flux crossing the surface defined by φ = π2, 1 ≤ ρ ≤ 2 m, and 0 ≤ z ≤ 5 m?

A linear accelerator uses RF (radio frequency) electric fields to accelerate electrons. If the frequency of the RF field is 3 GHz and the phase velocity of the wave is equal to the speed of light (approximately 3 × 108 m/s), what is the wavelength of the RF field?

Given a coaxial cable with a characteristic impedance of 75 Ω, an inner conductor diameter of 1.5 mm, and a dielectric constant of 2.0, calculate the outer conductor diameter.
