Explanation:
Mechanical energy (the sum of potential and kinetic energy) is constant:
ME = PE + KE
ME = PE + ½ mv²
PE = ME − ½ mv²
So the slope of the line is -½ of the mass.
I am not sure exactly maybe u should ask a friend
All of them are examples of energy being transferred by waves<span />
#1 is sand dune , #2 glaciers , #3 sand sediments hence small mass and #4 is <span> moraine .</span>
