By what percent must one increase the tension in a guitar string to change the speed of waves on the string from 328 m/s to 363 m/s?
show your work and the equations you used.

22.47 %

Explanation:

v 1 = 328 m/s, v 2 = 363 m/s

We know that the velocity of a wave in a stretch string is directly proportional to the square root of the tension in the string.

Percentage increase in the tension

                                                  = \left ( \frac{1}{0.8165}-1 \right )\times 100

                                                 = 22.47 %

answer is c

explanation:

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
