The answer is A because there’s so much heat in the core and pressure because of all of the layers of the earth
Answer: 6.12metres
Explanation:
The wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ
Recall that Wavespeed (V) = Frequency F x wavelength λ
V = F λ
In this case,
Wavespeed of sound = 1530 m/s
Frequency of sound = 2.50 x 10^2 Hz
Wavelength = ? (let the unknown value be Z)
Apply V = F λ
1530 m/s = 2.50 x 10^2 Hz x Z
Z = (1530 m/s / 2.50 x 10^2 Hz)
Z = (1530 m/s / 250Hz)
Z = 6.12m
Thus, the wavelength of sound in sea water is 6.12m
Answer:
Explanation:
when we get out of the water we feel quite cold due to the latent heat of evaporation of water.
Water at our body gets converted into gas and leaves behind the cooling effect which makes us feel cold.
While when we are inside the pool we are in constant touch of water, therefore, we get the warmth of the water and it becomes difficult to bear it.
Gas has no defined shape or defined volume. Which means that a gas would be able to expand to fill its container.
Answer:
cellular respiration.
explanation: cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
