Solar power : photovoltaic effect : converts sunlight into electricity : when silicon absorbs light & release electrons : electrons used to make electricity
Answer:
Solar power is a type of energy resource.
It comes from the sun and can be used to power homes and buildings.
Solar power is renewable, meaning it won't run out.
To calculate the energy generated by solar panels, you can use the formula: Energy = Power x Time.
The formula used to convert sunlight into electricity is called the photovoltaic effect.
When using solar power, it's important to watch for the amount of sunlight available, as this affects the amount of energy that can be generated.
An example of using solar power is using solar panels on a house to generate electricity.
A real-world example of solar power is the large-scale solar farms used to generate electricity for cities and towns.
Answer: Solar power is a renewable energy resource.
What to watch: The amount of sunlight available
Analogy: Solar power is like a free and endless supply of batteries that charge themselves using sunlight.
The photovoltaic effect is a way to convert sunlight into electricity.
This effect occurs when certain materials, such as silicon, absorb light and release electrons.
The released electrons can then be used to generate an electric current.
The formula used to calculate the power generated by a solar panel using the photovoltaic effect is Power = Voltage x Current.
This formula is known as the power equation.
When using the photovoltaic effect to generate electricity, it's important to watch for the amount of sunlight available, as this affects the amount of power that can be generated.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

What information does the periodic table give you?
Answers
The periodic table contains information about each of the known elements. It includes the name of each element, its atomic number, its atomic mass and its chemical symbol.
The periodic table is divided using groups (columns) and periods (rows).
Each specific group or period has a specific pattern in the elements.
The modern periodic table is arranged in order of increasing atomic number.
I’m not really sure what information what you were asking for but I hope this helps..
The modern periodic table was created by Dmitri Mendeleev with the main goal of showing rows and columns with a logic arrangement of chemical elements.
In each column, the groups, the elements have the same number of electrons in the outermost shells. While the rows are called periods or series.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Does a wave transport energy, matter, or both? Explain your answer in 1-2 sentences (Will give brainliest)
Answers
Answer in Explanation form
A wave carries its energy without transporting matter. Waves are seen to move into an ocean or lake, yet the water always returns to its resting position.
A wave transports energy, but not matter. Waves are created by the transfer of energy from one point to another, and they are able to transmit this energy over long distances without physically moving any matter.
What is a wave?A wave is a disturbance that travels through space and matter, transferring energy from one place to another. Waves can take many forms, including mechanical waves (such as sound waves and seismic waves) and electromagnetic waves (such as light waves and radio waves).
Waves are created by the transfer of energy from one point to another, and they are able to transmit this energy over long distances without physically moving any matter. For example, sound waves can transmit energy through the air without moving any air molecules, and light waves can transmit energy through empty space without moving any particles. However, waves can still have an impact on matter by interacting with it, such as when a wave causes an object to vibrate or when a wave of light is absorbed by a substance.

4. List factors that influence the rate of a chemical reaction.
5. Choose one of the factors you listed in your answer to question 2, and explain how it affects reaction rate.
Answers
Answer:
This is where google becomes your best friend but I got you
Explanation:
1. A theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
2. Collision theory says that chemical reactions occur by the collisions between atoms and molecules, so the more collisions the faster the rate of the chemical reactions.
3. The speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.
4. There are four main factors that can affect the reaction rate of a chemical reaction:
Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. ...
Physical state of the reactants and surface area. ...
Temperature. ...
Presence of a catalyst.
Answer:
1. a theory that says a chemical reaction takes place when particles of the reactants collide with sufficient energy to initiate the reaction
2. Increasing the concentration of the reactants, the faster the particles will collide so the reaction rate will be faster
3. a measure of how fast a reaction takes place

which phrase describes air pressure O decreases with denser air O decreases as altitude decreases O equals mass divIded by Volume O decreases as a result of fewer air particles pushing down
Answers
Air pressure decreases as altitude decreases. This phenomenon occurs because the atmosphere's density diminishes with increasing height above the Earth's surface and the correct option is option 2
As one ascends to higher altitudes, there are fewer air particles above, leading to a decrease in air density. Consequently, the pressure exerted by the air decreases at higher elevations.
Conversely, at lower altitudes, the air is denser due to the larger number of air particles above, resulting in higher air pressure. This relationship between air pressure and altitude is crucial for understanding weather patterns, climate changes, and the functioning of various natural processes on Earth.
Thus, the ideal selection is option 2.

these days cloths made out of a mixture of synthetic fiber and natural fibers are more popular than those made purly out of synthetic fiber. Discuss the reason for this
Answers
Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .
Explanation:
Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .
Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.
