Final answer:
The symbol ω represents angular frequency in physics, measuring radians per second, while in electrical engineering Q represents the ohm unit for resistance.
Step-by-step explanation:
The symbol ω represents the angular frequency in physics. Angular frequency is the rate of change of the phase of a sinusoidal waveform, or the rate of rotation. It is measured in radians per second and is given by the formula ω = 2πf, where f is the ordinary frequency. In the context of electrical engineering, the symbol Q (the Greek letter uppercase omega) refers to ohm, which is the unit of electrical resistance, inductance, or impedance. One ohm equals one volt per amp.
