Answer:
Answer is D.
Step-by-step explanation:
![v^{2} =\frac{3P}{mn}\\](https://tex.z-dn.net/?f=v%5E%7B2%7D%20%3D%5Cfrac%7B3P%7D%7Bmn%7D%5C%5C)
Multiply both sides by m.
![mv^{2} =\frac{3P}{n}\\](https://tex.z-dn.net/?f=mv%5E%7B2%7D%20%3D%5Cfrac%7B3P%7D%7Bn%7D%5C%5C)
Divide both sides by
.
![m =\frac{3P}{nv^{2}}\\](https://tex.z-dn.net/?f=m%20%3D%5Cfrac%7B3P%7D%7Bnv%5E%7B2%7D%7D%5C%5C)
