Which of these is an example of potential energy?

dimaraw [331]

An example of potential energy is 1. The air in an inflated balloon.

Potential energy is stored energy. The air in the inflated balloon has elastic potential energy because it is being stored in the ballon. If the mouth of the inflated balloon is released or if the balloon is popped, the potential energy in the balloon transforms into kinetic energy.
All of the other answer choices are examples of kinetic energy or energy in motion. The wrecking ball, boulder, and water are all moving which means that they all contain kinetic energy, not potential energy.

Yeast cells are recovered from a fermentation broth by using a tubular centrifuge. Sixty percent of the cells are recovered at a

Serga [27]

Answer:

$\\ \omega = 5033.22 \ rpm$

Explanation:

Given that:

$R_1 = 0.6\\\\R_2 = 0.95\\\\\omega_1 = 4000 \ rpm\\\\\omega_2 = ???\\\\Q_1 = 12\ l/min\\\\Q_2 = 12\ l/min$

For a continuous centrifuge ; solid recovery R ∝ $\frac{\omega^2}{Q}$

where;

ω = angular velocity of the centrifuge in rpm

Q = flow rate

SO;

$R_1 \alpha \frac{4000^2}{12}$

$R_2 \alpha \frac{\omega^2}{12}$

$\frac{R_1}{R_2} = \frac{4000^2}{12}$ ÷ $\frac{\omega^2 }{12}$

$\frac{R_1}{R_2} = \frac{4000^2}{12} * \frac{12}{\omega^2}$

$\frac{R_1}{R_2} = \frac{4000^2}{\omega^2}\\\\\frac{0.6}{0.95} = \frac{4000^2}{\omega^2}$

${\omega^2} = \frac{4000^2*0.95}{0.6}\\\\\\{\omega} = \sqrt{ \frac{4000^2*0.95}{0.6}}\\\\\\ \omega = 5033.22 \ rpm$

PLEASE GET BACK WITH ME ASAP :,(

1.) Photosynthesis and cellular respiration are often described as been chemically opposite because the product of the photosynthesis process is the reactant of the cellular respiration process and vice versa.

The reactants of cellular respiration are glucose and oxygen and these happen to be the products of photosynthesis also. During the process of photosynthesis, plants take in carbon dioxide and water in the presence of sunlight to produce glucose and oxygen. During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water, which are the reactants of the photosynthesis process.

2.) Photosynthesis and cellular processes are related to each other, this is because, the photosynthesis process produces the glucose, which cellular respiration used to synthesis energy in the cells of living organisms. Thus, the glucose producing plants depend on the living organisms that carried out cellular respiration to produce carbon dioxide and water, which is the necessary reactants for photosynthesis process. The organisms using cellular respiration also depend on plants to produce glucose and oxygen for their use.

Hope this helps,
