Energy Efficiency =
Useful Energy Output/Total Energy
Input x 100 (%)
If a power plant uses 100 units of
energy to create electricity and the
output is 5 units, where does the
95% of the energy input go?
A. lost as heat
B. lost as gas
C. escapes the system as potential energy

Answers

I looked it up and the answer is A because lots of electricity is lost as heat through conductors. i also found stuff for the other answers but this seemed the most accurate and credible.

If a power plant uses 100 units of energy to create electricity and the output is 5 units, 95% of the energy input goes as lost as heat.

Could you ever create a machine where 100% of the input energy would turn into output energy?

No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance.

How do you calculate the energy efficiency of a power plant?

To express the efficiency of a generator or power plant as a percentage, divide the equivalent Btu content of a kWh of electricity (3,412 Btu) by the heat rate. For example, if the heat rate is 10,500 Btu, the efficiency is 33%. If the heat rate is 7,500 Btu, the efficiency is 45%.

Bacteria Natural Selection

Answers

Answer:

Bacterial resistance arises through the simple process of natural selection. Bacteria divide rapidly, but DNA replication is imperfect. In the presence of antibiotics, while most bacteria are killed, a small number of resistant mutants may survive and take over.

Explanation:

When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features

Anorexia (also known as Anorexia nervosa) is an eating disorder characterized by abnormally low body weight. It's similar to the starving of oneself to achieve lower weight, but this is unhealthy. It's very common (more than 3 million cases per year in US) and is treatable. This can last for several months or years and is more common in females from ages 18–35.

Some symptoms include:

Extreme weight loss

Thin appearance  

Fatigue and insomnia  

Bluish discoloration of the fingers

Hair that thins, breaks or falls out  

Amenorrhea (absence of menstruation)  

Dry or yellowish skin  

Dehydration

Bulimia (also known as Bulimia nervosa) is an eating disorder characterized by binge eating, followed by methods to avoid weight gain (ie. vomiting). It's very common (more than 3 million cases per year in US) and is treatable.  It can last several years or be lifelong and are more common in females from ages 18–35.

Some symptoms include:

Binge eating

Forceful vomiting

Long-term fear of gaining weight  

Overuse of laxatives or diuretics

Use of supplements or herbs for weight loss

Excessive exercises

Stained teeth (from stomach acid)

Obesity is a condition characterized by abnormal or excessive fat accumulation. It's extremely common (more than 3 million cases per year in US) but is treatable. It can last several years or be lifelong. Family history may increase likelihood for some types.

Some symptoms include:

Above average body weight  

Sleep apnea- a condition in which breathing is irregular and periodically stops during sleep  

Skin problems caused by moisture that accumulates in the folds of your skin  

Osteoarthritis in weight-bearing joints, especially the knees

Parkinson's disease is a chronic and progressive movement disorder, meaning it weakens the control of movements of the body over time. It's fairly common (more than 200,000 cases per year in US). There are treatments to manage the condition but there is no known cure. This can last several years or be lifelong. It's more common in 60+ years old males.

Some symptoms include:

Tremors, trembling of hands, arms, legs, jaw and face

Stiffness of the arms, legs and trunk

Slowness of movement

Poor balance and coordination

Speech difficulty

What do you mean by Constellations?

Constellations may be defined as clusters of stars that form a recognizable pattern and were imagined in order to construct noticeable and apparent configurations of objects or creatures in the sky, especially at night.

These groups of stars are also present in the day but they are not perceived due to the extremely high light of the sun. So, they form patterns in the night sky. These groups of stars are not specifically present as they are distributed randomly and can form new images.

Therefore, the correct options for this question are A, B, and D.

B. Because the Sun is tilted on its axis, parts of Earth get more sunlight during different times of Earth's yearly orbit.
O C. Because Earth is tilted on its axis, the stars reflect more light during different times of the Earth's yearly orbit.
D. Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit.

Answers

Answer:

Answer

Explanation:

B because the more the sun is titled the more heat=different season.

Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit. As Earth orbits around the Sun, its axis is tilted at an angle of about 23.5 degrees. Hence the correct option is D.

Why do the temperatures change over the months?

The temperatures change over the months primarily because of Earth's axial tilt. As the Earth rotates around the sun, the angle at which sunlight hits different parts of the Earth changes.

This is because the Earth's axis is tilted about 23.5 degrees relative to its orbit around the sun. When a particular hemisphere is tilted toward the sun, it receives more direct sunlight, resulting in warmer temperatures.

Conversely, when that hemisphere is tilted away from the sun, it receives less direct sunlight, resulting in cooler temperatures. This cycle repeats itself annually, causing changes in temperatures over the months.

Hence the correct option is D.
