[单选题]
A string is connected to a mechanical gpe,w.x-3lb 8zqy - dboscillator on one e v7f frs (gy6y+nd and to a cube-shaped mass ???? = 8.0 ????????, at the other end as shown. The oscillator vibrates the st 6 f fv7s(yygr+ring with a frequency of f producing the standing wave in the figure on the left. When the mass is submerged completely in water, the string vibrates in the standing wave pattern shown.
16.37:What is the value of the ratio for the tension when the mass is submerged in water to the
tension when the mass is hanging in air?
A. 4
B. 2
C. $\frac{1}{\sqrt{2}}$
D. $\frac{1}{2}$
E. $\frac{1}{4}$
