Noether theorem (Noether):
A theorem which revels that symmetries are what gives increase to conserved quantities. For example, translational symmetry (the fact that the laws of physics work the similar in all places) gives increase to conservation of momentum, as position & momentum are complementary. In addition, conservation of energy is mention by time symmetry, & conservation of angular momentum is mentioned by isotropy.

A certain particle has a lifetime of 1.00 x10 -7 s when measured at rest. How far does it go before decaying if its speed is 0.99c when it is created? The lifetime of particle
Ohm's law (G. Ohm; 1827): The ratio of the potential difference among the ends of a conductor to the current passing through it is constant; the constant of proportionality is
1. We want to measure a sinusoidal signal (frequency 100 Hz) expected to be of strength 1 mV RMS in the presence of noise of peak amplitude 3 mV. (a) If our A/D converter has
In an experiment of Quink tube source freequence 100 Hz is used to find 2nd maxima to 4th manima movalbe part of tube displaced by 1cm then calculate speed of sound in air
what is it?
Will there be any change in hz of sound if two vibrating body has the similar hz Ans) Yes it depends on the path difference among them... Like in destructive inteference u
