In metric that means multiplying or dividing by 10, 100, 1000, etc. It consists of a partial word like "kilo" or "milli". For example, the prefix "kilo" means "times a thousand" or " one thousand of" the units in question. So "kilometer" means one thousand meters and "kilogram" means one thousand grams.

Answer:Food contains chemical potential energy. As our bodies digest it, the stored energy is converted into energy for us to move and grow.
Explanation:
Answer:
10.58 ft
Explanation:
Force, F = 1.4 N
Diameter of membrane = 7.4 mm
radius of membrane, r = 7.4 / 2 = 3.7 mm = 3.7 x 10^-3 m
Area, A = 3.14 x (3.7 x 10^-3)^2 = 4.3 x 10^-5 m^2
Density, d = 1.03 x 10^3 kg/m^3
Pressure at depth, P = h x d x g
Let h be the depth.
Pressure = force / Area
h x 1.03 x 10^3 x 9.8 = 1.4 / (4.3 x 10^-5)
h = 3.225 m = 10.58 ft
Thus, the depth of water is 10.58 ft.
As we know that speed of sound is
![v = 330 m/s](https://tex.z-dn.net/?f=v%20%3D%20330%20m%2Fs)
frequency of sound is
![f= 1320 Hz](https://tex.z-dn.net/?f=f%3D%201320%20Hz)
now we know that frequency of sound and speed of sound is related to each other by the following formula
![speed = frequency * wavelength](https://tex.z-dn.net/?f=speed%20%3D%20frequency%20%2A%20wavelength)
![v = \lambda * f](https://tex.z-dn.net/?f=v%20%3D%20%5Clambda%20%2A%20f)
![330 = 1320 * \lambda](https://tex.z-dn.net/?f=330%20%3D%201320%20%2A%20%5Clambda)
![\lambda = 0.25 m](https://tex.z-dn.net/?f=%5Clambda%20%3D%200.25%20m)
<em>so wavelength of sound is 25 cm or 0.25 m</em>
