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.
A motor has an output of 4.8kW, an efficiency of 80% and a power factor of 0.625 lagging when operated from a 240V, 50Hz supply. It is needed to improve the power factor to 0.9
What is radioactivity? Radioactivity: The process of spontaneous disintegration of the nuclei of heavy elements with the emission of certain radiations is known as natural ra
A microphone is attached to a spring that is suspended from the ceiling. Directly below on the floor is a stationary 440 Hzsource of sound. The microphone vibrates up and down in s
An electric iron draws a current of 0.5A.The voltage is 200V. Calculate the amount of charge flowing through it in 1 hour.
UNIFORM VELOCITY: If a body covers equal displacements in equivalent intervals of time, though the smallest intervals may be, then the velocity of the body is said to be unifor
Stefan-Boltzmann law (Stefan, L. Boltzmann): The radiated power P (it is rate of emission of electromagnetic energy) of hot body is proportional to the radiating surface area,
CENTRE OF GRAVITY: Consider a body as an accumulation of many small masses (molecules), all subject to gravitational attraction. The total weight, which is a force , is
1. A child pulls a toy car weighing 0.20 kg across a smooth floor by means of a string attached to it. If the string makes an angle of 60° to the floor and the child pulls with a f
They are exactly analogous to water pressure and water flow by a hose. That's why flowing electrons is known as a current, just like a water current. Voltage is the electromotiv
Define, with the help of diagram, the principle and working of an a.c. Generator. Write the expression for the e.m.f. generated in the coil in terms of its speed of rotation
