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
A. is the answer. Hope this helps you! :p
The one that is loosing electron is oxidation process and the one that is gaining electron is reduction.
b) Reduction reaction occur at cathode while oxidation reaction occur at Anode.
Explanation:
The main difference between the reduction and oxidation process is based on gaining and loosing of electron.
Reduction and oxidation both occur simultaneously. one is loosing electron and other is gaining. The one that is loosing electron is oxidation process and the one that is gaining electron is reduction.
B) Reduction reaction occur at cathode while oxidation reaction occur at Anode
