[单选题]
A string is connecte *: aw1eba vyj/d to a mechanical oscill *b x4ms-f n9-bu*7ou bx-igkiator on one end and to a cube-shaped mass ???? = 8.0 ????????, at the other end as shown. The oscillator b*f-smiux 7--4kbxg*buno 9i vibrates the string 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
