The sinusoidal voltage source in the circuit vg = 240 cos(5,000t) vrms. a. find the thévenin voltage with respect to the terminals a, b. express your answer in polar form (make the magnitude positive and the angle negative). | vth | = answer v angle = answer ° (degrees)
b. find the thévenin impedance with respect to the terminals a, b. express your answer in polar form (make the magnitude positive and the angle negative). | zab | = answer ω (ohm) angle = answer ° (degrees)

temp rises, and expansion

your answer is, orbit around the nucleus

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
