Electrons in the picture tube of an old-style television travel at 1.25 × 108 m/s. At this speed, how much time does it take the electrons to travel 11.5 inches? State your answer in microseconds (µs).

Speed of electron "v"= 1.25× 10^⁸ m/s . Distance travel "d"= 11.5 Inches = 0.2921m Let Time take be t . Time= Distance / speed Time= 0.2921/(1.25×10^⁸) t = 2.337×10^-⁹ sec .Or 0.0023×10^-⁶ sec .
