In the picture below identify the type of wave in the top picture. * Compressional
Transverse
Surface
Combination

Answer; transverse wave
Explanation;

In transverse waves the particles vibrate perpendicular to the wave's motion.

Mary concludes that the foam rubber balls’ acceleration during the collision was THE SAME AS the steel balls’ acceleration. She concludes that the collision between the foam rubber balls is an ELASTIC collision.

The masses of the two objects are the same therefore its acceleration would also become the same. It is an elastic collision because little or less friction occurred in the situation creating kinetic energy.
