The effect is due to static electricity when Lucas rubbed plastic ruler on the sweater he caused the ruler to become negatively charged due to rubbing creating a negative charge that is carried by electrons so when he waved above pieces of paper positive charges present in the atoms of paper became attracted to negatively charged ruler.

Okay, so this is physics. What is the meaning of KE? It's Kinetic Energy. What is the meaning of GPE? It's Gravitational Potential Energy. So how do you calculate either, and what are their significances? Kinetic -> motion, Gravitational potential energy -> energy that can be used to do work due to gravity. So is the bowling ball moving, or is it someplace it can fall from, or both?
Kinetic energy is calculated as 1/2 * mv^2, where m is the mass of the object, and v is the velocity. Potential energy for conservative forces is the product of the force and the distance over which it can do work. Thus in the case of GPE, it is the weight multiplied by the height, as gravity is a conservative force. What is the weight? It's not equal to the mass.
Hopefully these hints will get you thinking.

Answer:
Anaerobic Respiration
Explanation:
The first step in both anaerobic and aerobic respiration is called glycolysis. This is the process of taking one glucose (sugar) molecule and breaking it down into pyruvate and energy (2 ATP). ... The second step in anaerobic respiration is called fermentation.
