C, due to stuff and whatnot
Balenced
Think of it this way if 2 same weight and same speed objects were racing toward each other perfectly straight then their forces will cancel out and the movement afterwords will be 0
Since we have , v=f×lambda (wavelength). Where v equals 350m/s and wavelength equals 3.80. so it will become f = v/lambda=350/3.80=92.1052Hz
Answer:

Explanation:
Bulk modulus is defined as the relative change in the volume of a body produced by a unit of compressive acting uniformly over its surface:

Hence the density of the seawater at a depth of 680atm is calculated as:-

<span>Density can be calculated and found by dividing the sample's mass by its volume. D=m/v</span>
