Hey there!
The statement that would basically be the best description would be It is a permanent magnet. This is all about some magnetic field, <span>Field lines point out from one end of an object and loop around to enter the other end of the object would be a best descriptive of a magnetic the would be permanent.</span>
Answer:
C. 14.93 m
Explanation:
The given frequency of the wave, f = 100 Hz
The given equation for the wave speed, <em>v</em>, is presented as follows;
v = f × λ
The speed of sound in water, v = 1,493 m/s
Therefore, we get;
The wavelength, λ = v/f
∴ λ = 1,493 m/s/(100 Hz) = 14.93 m
The wavelength, λ = 14.93 m.
Refraction. refraction is always accompanied by a wavelength and speed change
