How far away can the siren be heard? The physics of sound will reduce the volume of the siren as the distance from the siren increases. With today’s modern vehicles, the effective range of the siren at a 90-degree intersection is often no more than 80 feet. Does pitch change with distance? Sound waves that […]

What is real and apparent Expansivity? The real (or absolute) expansivity of a liquid is the fraction of its volume by which it expands per kelvin rise in temperature. The apparent expansivity of a liquid is the fraction of its volume by which the liquid appears to expand per kelvin rise in temperature when heated […]

Does frequency change power? Frequency of the system will vary as load and generation change. Increasing the mechanical input power to a synchronous generator will not greatly affect the system frequency but will produce more electric power from that unit. Can I use a 60 Hz device in a 50 Hz power frequency? Electrical machines […]
