important facts of liquid nitrogen

Nitrogen forms nearly 78% of the volume of air. Earlier, the useful significance of nitrogen was not known and it was considered to be inactive. At that time, nitrogen was considered important only because it was known to moderate the processes of respi..

Some Important Aspects of Doppler Effect - When a source moves towards a stationary observer the apparent frequency, according to equation When the observer moves towards a stationary source, the apparent frequency, according to equation In both the cases, the apparent frequency is greate..

Since the denominator in the RHS of the above equation is less than 1, f 1 > f 2 . Thus, the increase in the apparent frequency is greater when the source approaches a stationary observer than, when the observer approaches a stationary source. In other words, Doppler effect in sound is 'a..
