Is amount of “ground” an object moves from its starting point and is how much “ground” and object covers in total. question options: displacement, distance speed, displacement distance, displacement movement, distance

I believe the question talks about displacement and distance. The difference of the two is that displacement is the linear distance or shortest distance drawn from the starting point until the final point while distance is the whole trip that is covered, so the answer is:

Displacement, distance

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

wavelength divides in half and speed stays the same.
