The correct answer is option C

Doppler effect can be defined as the change in wavelength or frequency of a wave with rest to the observer who is moving relative to the source of the  sound wave.

This technique is used in baseball to measure the change in frequency of the sound waves.

The coach uses a radar to measure the speed of an approaching pitched baseball.

Answer:

Secondary Succession

Explanation:

Secondary Succession is faster than primary succession because soil is already there, and the soil usually contains many nutrients.

Examples: Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.
