The water in a reservoir behind a dam is an example of potential energy. The stored energy in the reservoir is converted into kinetic <span>energy (motion) as the water </span>flows<span> down a large pipe and spins a turbine. </span>Both use a power<span> source to turn the propellers of a machine </span>called<span> a turbine. As the turbine spins, it turns a metal shaft connected an </span>electric<span> generator, which is basically a motor that </span>produces electricity. In the case of a hydroelectric dam, it's flowing water<span> that's used as the </span>power<span> source to turn the turbine.</span>
Step 1: Identify the formula needed to solve this problem.
The formula for kinetic energy (KE) is:
KE = 1/2m~v^2
m = mass
v = velocity
Step 2: Make a list of the values given in the question.
mass (m) = 30 g
velocity (v) = 200 m/s

I can help you with this one but I need the image to help you :)
Answer;
Glucose
The nutrient that can be used to produce energy in the absence of oxygen is glucose.
Explanation;
Production of energy without using glucose is called anaerobic respiration. During this type of respiration less energy is released than the case of aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces an oxygen debt, which is the amount of oxygen needed to break lactic acid to carbon dioxide and water.
<span>Fossil records are described as the position of found fossils all
through the surface or the layers of the earth. The older the fossils are, the
deeper it is found. Fossil records are also considered to be gathered
information about the total number of the discovered fossils and the data obtained
from them. Fossil records are important guides to determine how life existed
before. If you are to assemble a fossil, you will be able to see and tell the
evolutionary changes that happened over the past years. Fossil records are evidences
pointing out that life before is totally different from now. </span>
