Explanation:
D) 75 J
Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.
With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.

Systemic circulation is the one that oxygenates all the body.
Starting from the left atrium, through the left ventricle, and the aorta and its branches to the body.
After the tissues do the exchange, the deoxygenated blood goes back to the right atrium to starts the pulmonary circulation, and then the cycle starts again.
