When the football is snapped, which player will have the smallest change in kinetic energy?
DanielleElmas [232]
When you are finding the kinetic energy, it is best to keep this formula in mind.

Ek = 1/2mv²

Where m is mass and v is velocity. Basically sub the numbers in to find the kinetic energy for each. In this case, subbing all the numbers, the smallest change in kinetic energy is the Lineman with a kinetic energy of just 540N.

Write the formula that shows the release of energy by the mitochondria
Pie

Answer:

Mitochondria is the organelle where cellular respiration takes place. Cellular respiration can be described as a process in which oxygen and glucose are converted into carbon dioxide and water along with the release of ATP. This reaction can be written as:

Glucose + Oxygen → Carbon dioxide + Water + ATP molecules

C6H12O6 +   6O2→  6CO2 +  6H2O +  ATP

The ATP made can be broken down so that energy is released.

ATP + H2O → ADP + Pi + free energy

Are genes one-dimensional or 3-dimensional
yKpoI14uk [10]

Answer:

<em>Genes are one dimensional.</em>

Explanation:

The genes are made up of segments of DNA. The DNA has a three dimensional structure as coiling and super-coiling occurs in it to give it a three dimensional structure. But genes itself are one- dimensional. Genes are the hereditary molecules.  

The genes makes particular proteins. Proteins also have three dimensional structure as they undergo coiling and super-coiling.
