Following equations represent four travelling waves. Which one has the maximum speed? In a typical 555 astable multivibrator circuit, if R A = R B = 2.2 kΩ and C = 0.1 µF then the free-running frequency is: Q factor of Quartz . . . . . . . . If the magnitude of $$\overrightarrow {\text{H}} $$ in a plane wave is 1 A/m, what is the magnitude of $$\overrightarrow {\text{E}} $$ for a plane wave in free space: If $$F\left( s \right) = L\left| {f\left( t \right)} \right| = {K \over {\left( {s + 1} \right)\left( {{s^2} + 4} \right)}},$$ then $$\mathop {\lim }\limits_{t \to \infty } f\left( t \right)$$ is given by
