Answer:
C. After running 20 miles
Explanation:
Anaerobic respiration only occurs when an organism lacks all the oxygen we need to function. After running 20 miles, you will be out of breath, and you will have been using more energy than your respiratory system could produce alone. Due to this, your body will start using some of your energy stored within cells in order to continue functioning. This kind of respiration is basically 'burning calories'.
A swinging pendulum has its greatest kinetic energy and least potential energy in the vertical position in which its speed is greatest and height least.
It has its least kinetic energy and greatest potential energy at the extremities of its swing, in which its speed is zero and its height greatest. As the pendulum moves, energy is continuously passing back and forth between the two forms.
Neglecting friction at the pivot and air resistance, the mechanical energy (sum of kinetic and potential energies) of the pendulum is constant.
