A stereo speaker is made of a flexible cone-shaped material that vibrates, creating a sound wave. A sound wave formed be a speaker travels through air to your ear as a series of compressions and rarefactions of air molecules.
Which statement classifies the sound wave?
transverse wave in which the particles of the wave move in a direction parallel to the wave motion
longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion
transverse wave in which the particles of the wave move in a direction perpendicular to the wave motion
O longitudinal wave in which the particles of the wave move in a direction perpendicular to the wave motion

Ответ:
Using the information given in the question, we can't tell.
-- ' cm² ' is not a unit of volume, so the volume of the paper clip can't be 2cm² .
-- To calculate the density of anything, we need to divide its MASS by its volume. So, even if we did know the volume of the paper clip, we still don't know its mass, so we don't have enough information to calculate its density.
Sorry.
