Because 'acceleration' does NOT mean 'speeding up'.
It means ANY change in motion ... speeding up, slowing down,
or changing DIRECTION.
When traveling a roundabout, or any curved path, the direction
is constantly changing even if the speed is constant, so there is
constant acceleration going on.
You can’t solve it because you don’t have c in the question
Answer:

Any liquid takes form of the shape of the container it goes into.
Gasses take the form of the whole thing because it spreads throughout it.
Solids are already a shape so it cant take the shape of the container if it already has one. yk
Convert 10mm to metres = 0.01m
Wave speed = frequency *wavelength
= 4Hz*0.01m
= 0.04 m/s
Hope this helps
