The answer that would best complete the given description above would be the term DEFORMATION. All changes in the original shape and/or size of a rock body are called deformations. Hope this answers your question. Have a great day ahead!
I have no idea how too do that work sheet but try looking for the answer key online by searching for the name of the worksheet
Complete Question
The complete question is is shown on the first uploaded
Answer:
The elastic potential energy at point B is
The kinetic energy at point D is
Explanation:
Looking at the given point we can observe that mechanically energy(i.e potential and kinetic energy ) is conserved and it value is
So at point B
KE at point B is 50J
So
Now at point D
at point D is 25J
So
Solid. And it's where molecules don't move at all which means that no energy is required at all.
