Make U the subject of the formula S = $\sqrt{\frac{6}{u} - \frac{w}{2}}$

A.

u = $\frac{12}{2s^2}$

B.

u = $\frac{12}{2s+ w}$

C.

u = $\frac{12}{2s^2 + w}$

D.

u = $\frac{12}{2s^2}$ + w

View answer & explanation

Correct answer is C

S = $\sqrt{\frac{6}{u} - \frac{w}{2}}$

S = $\frac{12 - uw}{2u}$

2us² = 12 - uw

u(2s² + w) = 12

u = $\frac{12}{2s^2 + w}$
