I'll do coal. and maybe a little more.

Explanation:

Coal What is it?

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.

Coal How we obtain it:

Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.

Coal Pros:

Coal is plentiful in many places and it is easy to access through mining, so people rely on it to produce energy. Coal is easy to store. Once it is mined it can be safely stored with no hazard of fire or explosion like there is with gas or oil. It is relatively easy and inexpensive to convert coal into energy.

Coal Cons:

Coal is nonrenewable.  Coal contains the most CO2 per BTU, the largest contributor to global warming.  Severe environmental, social, and health, and safety impacts of coal mining.  The devastation of the environment around coal mines is heavy.  High cost of transporting coal to centralized power plants. Coal is really dirty and not good.

Solar What is it?

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.

Solar How we obtain it:

Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.

Solar Pros:

It's clean energy. Solar power is pollution-free and causes no greenhouse gases to be emitted after installation.  It has reduced dependence on foreign oil and fossil fuels.  It is renewable clean power that is available every day of the year, even cloudy days produce some power.  It gives a return on investment unlike paying for utility bills.

Solar Cons:

Solar doesn't work at night. Solar panels are not attractive. You can't install a home solar system yourself. My roof isn't right for solar. Solar hurts the environment. Not all solar panels are high quality.

Answer:

Correct options are C. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.

D. Energy stored in organic fuels are used for heat and electricity/ When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.

Explanation:

The breakdown of food leads to the release of chemical energy which was first stored in food. This energy is used to drive necessary functions of the body. A series of chemical reactions are involved in the breakdown of food and changing them into useful components for the cell.

Chemical energy is stored in circuits. When the battery is connected to a circuit, the chemical energy gets transferred into electrical energy.

Answer:

change, combine

Answer:

The Sun transforms nuclear energy into heat and light energy.

 A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles.

Answer: The energy from the sun is one great example of radiation. The sun emits light in a broad range of wavelengths which all contain energy. These waves are also discussed in the climate section for energy balance. The waves are emitted from the sun and travel through space and hit the earth and other planets.

EXTRA EXAMPLES: heat from a stove burner.

visible light from a candle.

x-rays from an x-ray machine.

An educated person has the ability to think clearly and independently and has good judgement.

Education is defined as purposeful activity directed towards achieving some objective, such as the dissemination of knowledge or the promotion of skills and character traits, whose aims include the development of understanding, rationality, kindness and honesty.

There are three main types of education which are as follows:

Formal, Informal and Non-formal.

The specialty of education is that it is pre-determined and pre-planned. It is regular and spatial i.e. time bound and regulated by the institutional. Proper education improves people's understanding of the world around them which make them less susceptible to the influence of others

Thus, an educated person has the ability to think clearly and independently and has good judgement.

Explanation:

Answer:

Time = 12.27seconds

Explanation:

Given

Speed = 25miles/hour

Distance = 150 yards = 150(0.000568182)miles

Distance (in miles) = 0.0852273miles

Get the time

Speed = Distance/Time

Answer:0.563

Explanation:

The kinetic energy produced in a toy car is equal to 0.563 J.

The energy exhibited by a moving body because of its motion is said to be its kinetic energy. Work should be done which can change the kinetic energy of a moving object.

The kinetic energy of a moving object can be determined from the formula mentioned below:

K.E. = ½mv²     where ‘m’ and ‘v’ is the mass, velocity of the object.

Potential Energy (P.E.)is energy that is stored in an object due to its position and can be expressed as P.E = mgh where h, m, and g are the height, mass, and gravitational acceleration respectively.

Given, the mass of the toy car =, m = 0.500 Kg

The velocity of the toy car, v = 80 m/s

The kinetic energy = (1/2)× 0.500 ×(1.50)²

K.E. = 0.563 J

Answer:

A

Explanation:

Can read mass precisely, commonly reading error of +0.05g

Mass is a measure of the amount of matter in a substance.  Mass can be measured using a triple beam balance. Hence option (A) is correct.

In physics, mass is a quantitative measurement of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force. The change caused by an applied force is smaller the more mass a body has. The kilograms serves as the unit of mass in the International System of Units (SI).

The conservation of mass principle states that no matter how an object's component pieces are rearranged, the object's overall mass remains constant. If a body splits into parts, the mass also splits into pieces, therefore the original mass is equal to the sum of the masses of the individual fragments. Alternatively, if two or more particles are combined, the mass of the resulting composite equals the total of the masses of the individual particles. This rule is not always accurate, though.
