A guitar string with a linear density of 2.0 g/m is stretched between supports that are 61 cm apart. The string is observed to form a standing wave with three antinodes when driven at a frequency of 446 Hz.
(a) What is the frequency of the fifth harmonic of this string?
(b) What is the tension in the string.
