Echolocation is also called bio sonar. It is the sonar used by several kinds of animals that <span>enables them to locate and discriminate objects by projecting high-frequency sound waves and listening for echoes as the sound waves reflect off objects. </span>
Dolphins and whales make these sounds at any time and at considerable depths. Sounds vary in volume, wavelength, frequency, and pattern.
The wavelength depends on the speed of
propagation (c).wavelength=c/f The speed of sound in water is c= 1450 m/s.
So, for bottlenose delphins the wavelength is:1450m/s / 110.5 kHz
1450 m/s / 110500 Hz =0.013 m = 0.13 mm
For whales the waveleng42.5 th is:1450m/s / 42.5 kHz =
1450m/s / 42500 Hz= 0.034 m = 0.34 mm

answer is polygenic inheritance
Answer:
Earth is fairly quicker than all the others, as they are so much larger.
Explanation:
Earth, our home planet of Earth speeds around the sun at a rate of 29.78 km/s. This means that we are traveling at 66,615 miles per hour. Mars, with an orbital speed of 24.077 km/s, or 53,858 miles per hour, travels considerably faster than the prior planets.
