Answer:
= 53.4 m/s
Explanation:
Velocity of a sound is given by the formula;
Velocity = Frequency × 2 (Length)
Frequency = 30 Hz
Length = 89 cm, equivalent to 0.89 M
Therefore;
Velocity = 30 × 2 ×0.89
Thus; the velocity or the speed of sound is 53.4 m/s
increase the time the force acts or you could increase the number of temptations.
