When a bicycle rider puts on the brakes of a bicycle, friction cause some of the mechanical energy to change into what type of energy?

Answers

Answer 1
Answer: Whenever friction gets ahold of energy, the only thing it can produce is heat.

Put on the brakes of a bicycle or a non-electric car, and the friction of the
brakes turns some of the kinetic energy of the bike or the car into heat.

Drop a space capsule through the atmosphere, and the friction of the air
turns some of its kinetic energy into heat.  That's why space capsules
that are going to come back have heat shields on them.

Drop a stone through the atmosphere, and the friction of the air turns
some of its kinetic energy into heat.  If it's going fast enough and gets
hot enough, we see a meteor ("shooting star").

Rub two sticks together, and the friction of their bark turns some of
their kinetic energy into heat.  Rub fast enough and you can use them
to start a campfire.

Can you help me understand force=mass x accleration

Answers

Force = mass * acceleration

Here is an equation for force, used to calculate force. 

Look at it this way:-

Joules is used to measure force, while mass is measured by kg. Acceleration is measured by m/s/s (meters per second per second, or meters per second squared.)

joules = m/s/s * kg

What happens to carbohydrates during cellular respiration?

Answers

The microorganisms trap the energy in the sunlight by the process called as photosynthesis.Carbohydrates is mainly glucose, but other types of microorganisms are not able to follow this process. Therefore these organisms must rely upon prformed carbohydrates in the environment so that it obtains energy for its metabolic processes.

Final answer:

Carbohydrates, in particular, glucose, are broken down during cellular respiration to produce ATP, carbon dioxide, and water. This process consists of three stages: glycolysis, the citric acid cycle, and electron transport phosphorylation.

Explanation:

During the process of cellular respiration, carbohydrates—specifically glucose, which is a simple sugar—are broken down to produce energy in the form of ATP (adenosine triphosphate). This is a vital process carried out by all living organisms.

This complex process happens in three distinct stages: glycolysis, the citric acid cycle also referred to as the Krebs cycle, and electron transport phosphorylation also known as oxidative phosphorylation.

First, during glycolysis, one molecule of glucose gets broken down into two molecules of pyruvic acid and there is a net output of two ATP molecules. Next, the two molecules of pyruvic acid go through the citric acid cycle where they are oxidized to form carbon dioxide. Finally, during the electron transport chain, electrons are transferred through a series of proteins leading to the creation of water and producing a large amount of ATP.

Overall, the byproducts of this process are carbon dioxide and water, which are released as waste products.
