Answer:
594.8 Hz
Explanation:
Parameters given:
Speed of sound, v = 345 m/s
Wavelength = 58 cm = 0.58 m
Speed of a wave is given as:
Speed = wavelength * frequency
Therefore:
Frequency = Speed/Wavelength
Frequency = 345/0.58
Frequency = 594.8 Hz
Answer:
Because most of the human body (about 70% of it) consists of water
Explanation:
The main reason why the specific heat capacity of the human body is very close to that of water is that water makes approximately 70% of the substances of which the human body consists. However, the human body has a slightly smaller specific heat capacity than water, because it contains also other elements/substances, and since water is one of the substances with the higher specific heat capacity at all, the specific heat capacity of the body is a bit smaller.
