Answer:
Option B
Explanation:
Speed of a wave is denoted by:
v=fλ
where f is the frequency which is unchanged 15Hz and λ is the new wavelength which is 28m
v=fλ
Incompressible. Compressibility is determine by the amount of space between particles in each state.
There are 120 seconds in two minutes, so to find the answer, you multiply 20 x 120 to get 2400 meters.
