Density is defined as [mass] / [volume] .
The only choice listed with those physical dimensions is 'd' .
I think it’s, its direction would reinforce the original movement
There are longitudinal and transverse. Both types of mechanical waves require a medium, transport energy, and have defined wavelengths, frequencies, and speeds.
Differences are that transverse waves oscillate along a direction perpendicular to the direction of travel (like shaking a rope up and down). Longitudinal waves like oscillations along a spring and sound waves, oscillate back and forth along the direction of travel.
