What is periodic signal in data communication? Signals which repeat itself after a fixed time period are called Periodic Signals. Signals which do not repeat itself after a fixed time period are called Non-Periodic Signals. In data communications, we commonly use periodic analog signals and non-periodic digital signals. Is it possible to have a periodic […]

When would a moving car be in equilibrium?
When would a moving car be in equilibrium? The net force acting on the object must be zero. Therefore all forces balance in each direction. For example, a car moving along a highway at a constant speed is in equilibrium, as it is not accelerating in any forward or vertical direction. Mathematically, this is stated […]

What triggers a neural signal in the ear?
What triggers a neural signal in the ear? As the hair cells move up and down, their bristly structures bump up against an overlying membrane and tilt to one side. This tilting action causes pore-like channels, which are on the surface of the bristles, to open up. When that happens, certain chemicals rush in, creating […]
