If an athlete has X joules of mechanical energy at the top of the hill, he will have the same X amount of energy at the bottom of the hill.
<h3>What is mechanical energy?</h3>
Mechanical energy is the addition of kinetic and potential energy. It can be either kinetic or potential energy.
It is the energy possessed by the position or the motion of the body.
It is the energy present to perform any work.
So, the athlete will have X joule of energy at the top and bottom of the hill.
Thus, the correct option is a, X joules.

10. the thing in the slide wasnt centered so the microscope magnefied on nothing 11. mive it tight 12. idk what a um is
Answer:
a property whose value does not depend on the path taken to reach that specific value.
Explanation:
The balanced net reactiion for the following half cells will be
Sn + Cr²⁺ ---> Sn²⁺ + Cr
<h3>What are
Half cells ?</h3>
A half cell is one of the two electrodes of an electrochemical cell.
An electrochemical cell comprises two half cells, where every half cell contains an electrode and an electrolyte.
A salt bridge or direct contact is needed to connect two half cells.
The balanced net reactiion for the given half cells will be
Sn + Cr²⁺ ---> Sn²⁺ + Cr
