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 ratio of specific charge of a proton and an alfa-particle is: (1) 2 : 1 (2) 1 : 2 (3) 1 : 4 (4) 1 : 1 Ans:(1) 2 : 1
if in an interference pattern,the ratio between maximum and minimum intensities is 36:1,find the ratio between the amplitude and intensities of the two interfering waves.
Q What is Seebeck effect? Seebeck revealed that in a circuit consisting of two dissimilar metals like iron and copper an emf is developed when the junctions are maintained at
Mach number is the ratio of velocity of source to the velocity of sound. Mach Number = Velocity of Source / Velocity of Sound .
a) Orbital movement of electrons b) On the source of orbital motion of electrons c) These are repelled in an external magnetic field i.e. have a tendency to g
Faraday's laws of electrolysis (M. Faraday) Faraday's first law of electrolysis At time of electrolysis the amount of chemical change is proportion
The elctric field in a certain region of space has components E x = 6.0 N/C, E y = 7.0 N/C, and E z = 0. Find the electric flux though the surface x = 6 y , 0 x
Watt; W (after J. Watt, 1736-1819): The derived SI unit of power, explained as a power of 1 J acting onto a period of 1 s; thus it has units of J/s.
When a small size magnet is laid in two uniform magnetic fields and which are at right angles to each other, the magnet comes to rest at an angle Φ with respect to B h like that
