37. If the string used in Trial 10 were subjected to a tension of 3,600 N, the frequency of the resulting sound waves would be:
Your Answer is
Correct Answer is D
Explanation
Comparing trails 10 and 11 in table 2, when the tension decreases, the frequency decreases. So when the pulling force increases, the frequency should increase, only option D's 600Hz is greater than the 300Hz in trail 10, so choose D.
