Longitudinal Waves and Guitar Strings
According to the diagram this pressure wave consists of rarefactions and compressions. The compressions are regions of high pressure, whereas the air molecules are compressed within a small region of space. The rarefactions are regions of low pressure, while the air molecules are spread apart. This alternating pattern of compressions and rarefactions is called as a sound wave.
The Centralia power plant emits SO 2 at the rate of 150 g/s. It has an effective stack height of 50 m. Surface winds at 10 m are steady at 2.5 m/s and it is a fall afternoon. a
Q. It is possible to have motion in the absence of a force. Yes it is True, in the absence of a force a body will continue moving in a straight line and at a constant velocity
This is the virtue of a material resists flow of electric current. It should be as high as possible. When material is subjected to an electrical pressure then will always be a flow
A reversible power cycle receives energy H Q from a reservoir at temperature H T and rejects C Q to a reservoir at temperature C T. The work developed by the power cycle is used to
According to Eisenstein's quantum theory light propagates in the bundles of power, every packet being called as photon and possessing energy.
Q. Why does heat makes matter to expand? Answer:- Water contracts as it cools similar to all other liquids until it reaches a temperature of about 4 degrees Celsius at whi
In this case both source and screen are effectively at infinite distance from the diffracting device. Basic types: Diffraction at single slit, double slit and diffracting gratin
Why does the charge on the outer surface of a parallel plate capacitor doesn't change when it is connected by a battery. only inner surface charge gets affected. Why??
Explain Radioactivity and its Problems and Applications ? All radiation, electromagnetic as well as the kind from nuclear decay, takes its toll on living organisms. If the radiati
In the device shown in Figure, when the current in the primary coil of 1000 turns increases linearly from 1A to 6A in 200ms, an e.m.f. of 15V is induced into the secondary coil of
