Answer:
160J
Explanation:
Given parameters:
Frequency = 16Hz
Wavelength = 10m
Unknown:
Waves speed = ?
Solution:
Waves speed is the product of frequency and wavelength;
Waves speed = fλ
f is the frequency
λ is the wavelength
Now insert the parameters and solve;
Waves speed = 16 x 10 = 160J
If it i hot it makes it easy to clean
