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..

Nitrogen is present in the elemental state in the atmosphere to the extent of about 78% by volume. Nitrogen is important for life processes in all living organisms. But, free nitrogen cannot be directly assimilated by the living cells. Therefore, it is desir..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the environment as ammonia (ammonifica..
