279 millimeters is the answer
Answer:
Wave speed = 50 m
Explanation:
Given
Wavelength = 5 m
Frequency = 10 Hz = 10
wave speed = ?
We know that all waves have same relationship among wavelength λ, frequency f and speed v , which is given by
v = fλ
Therefore wave speed = 10 x 5 m = 50 m
The hypothesis would be can professional swimmer hold their breath longer than people who aren't
