Consider a guitar's A-string of a length 0.80 m and is stretched to a tension of 40 N. It vibrates at a fundamental frequency of 220 Hz. If the tension in the string is increased by a factor of 2.0, what happens to the fundamental frequency of this string?
A. It increases by a factor of 1.4.
B. It increases by a factor of 2.0.
C. It increases by a factor of 4.0.
D. (The fundamental frequency remains the same.)
