Explain how a school bus uses all of these energy types.

-Mechanical
-Chemical
-Electrical
-Thermal

Answers

Answer:

Mechanical

94 percent of all school buses in America are powered by diesel engines because of their reliability, durability and safety. Almost half of these (46 percent) rely on the cleanest, near-zero emission diesel engine technology.

Chemical

school bus uses petroleum as chemical potential energy.

Electrical

An electric bus draws electricity from the power grid and stores it in a battery that can be recharged once the electricity has been used up. This basically mirrors the way our electronics work. We plug them in and let the battery charge and then use them wirelessly until it's time to charge again

Thermal

They heat the cold coolant from engine's block to 160° F in as little as one hour, then pump it back to the vehicle's engine and heat exchangers. The result: engine is preheated and the vehicle's heat exchangers distribute an abundance of heat to the vehicle's interior.

Select the correct answer. A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich provide? A. 747 calories B. 542 calories C. 502 calories D. 367 calories E. 332 calories

Answers

Answer:

D. 367

Explanation:

If a roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates, it contains 367 calories of energy, hence option D is correct.

What is food energy?

Animals obtain the chemical energy known as "food energy" from their food in order to maintain their metabolism, which includes their muscular activity.

The majority of animals get most of their energy via aerobic respiration, which involves mixing carbs, lipids, and proteins with air or water-based oxygen.

To find the total calories, multiply the given biomolecules grams with their calorie count.

= 42 × 4 + 7 × 9 + 34 × 4

= 168 + 63 + 136

= 367 calories

Therefore, the sandwich provides 367 calories of energy, if it contains 42 g protein, 7 g fat, and 34 g carbohydrates.

A fishing trawler uses a large net to catch a school of small fish A logging company reseeds and replants in a forested area after cutting down trees for timber Crops are rotated in a farmer's field to maximize grain yields Coal is mined using underground tunnels to avoid the destruction of surface soils by strip mining

Answers

Answer:

A logging company reseeds and replants in a forested area after cutting down trees for timber

Explanation:

Answer:

Sustainability is the capacity to endure in a relatively ongoing way across various domains of life.[1] In the 21st century, it refers generally to the capacity for Earth's biosphere and human civilization to co-exist. It is also defined as the process of people maintaining change in a homeostasis-balanced environment, in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations.[2][failed verification] For many in the field, sustainability is defined through the following interconnected domains or pillars: environmental, economic and social,[3] which according to Fritjof Capra,[4] is based on the principles of systems thinking. Sub-domains of sustainable development have been considered also: cultural, technological and political.[5][6] According to Our Common Future, sustainable development is defined as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs."[7][8] Sustainable development may be the organizing principle of sustainability, yet others may view the two terms as paradoxical (seeing development as inherently unsustainable).[9]

Explain how humans are able to produce one type of hemoglobin as they develop in utero, then produce another to use after birth
