Whenever there is a relative speed among a source of sound and the listener, the apparent frequency of sound listen by the listener is dissimilar from the real frequency of sound emitted by the source.
When the distance among the source and listener is reducing the apparent frequency enhances. It describes the apparent frequency is more than the real frequency of voice. The reverse is also true.

INSTANTANEOUS ACCELERATION: The acceleration of the body at any certain instant during its motion is called to be an instantaneous acceleration.
cryotron?
The radioisotope 222 84 Po undergoes alpha decay to form an isotope of lead (lead has atomic number 82). Verify what the mass number of that isotope must be by writing a nuc
A capacitor and a coil are linked in series. The capacitor is charged and allowed to discharge by the coil. The current that will then flow by the capacitor-coil combination
Do fibers have losses? Everything in the universe is inefficient. It means that while a measured amount of something enters in a system, less comes out than initially went in.
Thomson experiment; Kelvin effect (Sir W. Thomson [later Lord Kelvin]): While an electric current pass through a conductor whose ends are maintained at distinct temperatures,
