The quantity of solar energy available to produce electricity is not affected by location on Earth's surface. This statement is true about solar energy.

Solar energy uses the sun's rays to create heat, light, and electricity. It is a renewable energy source. Heat may be employed in industrial activities like manufacturing whereas light can be immediately transformed into energy..

Solar energy may be converted directly into electrical power. A nonmechanical device called a photovoltaic cell is often constructed of silicon alloys. Photons, or solar energy particles, make up sunlight.

Due to the employment of particular grade silicon and silver during production, solar cells have a high cost of production. Solar cells don't have any moving components, so they may be readily installed in distant locations, but once installed, they don't require any care.

Thus, option D is correct.

What best describe the enthalpy of formation is that it is the energy change that happens when a substance forms from its elements

Option b

This goes to say that it is the heat change which occurred when one mole of substance is formed from its constituent elements.

Enthalpy can be defined as the sum total of the internal energy and the product of the pressure and volume of a system

So therefore, the entalphy of formation is

Earnings based on how much they sell

Explanation:

A sales presentation can be defined as series of talk given by a salesperson with the attempt to persuade someone or a potential customer to buy a particular product, by giving information it. Some salespersons resort to the use of dramatics so as to initiate and close the sale of a particular product by engaging in series of theatrical actions.

In sales and marketing, the term closing with respect to a sales can be defined as the process of making a business sale successful such as through the exchange of money for a particular product or goods.

For a salesperson to be able to close a sales, he or she require abilities such as courage, negotiation skills, listening ears and interpersonal skills to do so or achieve a successful sales. After a successful sales, they're entitled to a percentage of the amount made from selling a particular product or closing a deal based on what is stated in the contract. These amount of money earned with respect to each sales is generally referred to as commissions.

Commission can be defined as an amount of money earned based on how much a salesperson sell.

Answer:

Molarity of a solution is defined as

the amount of a substance in a certain volume of solution or the moles of a solute per liters of a solution and also known as the molar concentration of a solution.

The units of molarity are M or mol/L

Define molarity of a solution.

Molar concentration or Molarity is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.

c. The circulatory system moves oxygen throughout the body that is brought in by the respiratory system.

Explanation:

The circulatory system delivers oxygen and nutrients to cells and takes away wastes.

The respiratory system is the network of organs and tissues that help you breathe.

So, of the options, option c is correct.

Hope this helps!

The  statement which  best describes how two body systems work together to maintain homeostasis is that circulatory system moves oxygen throughout the body that is brought in by the respiratory system.

In biology, homeostasis  is the state of steady internal, physical, and chemical conditions maintained by living systems.This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range).

Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium, and calcium ions, as well as the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life.

Answer:

44.91% of Oxygen in Iron (III) hydroxide

Explanation:

To solve this question we must find the molar mass of Fe(OH)3 and the molar mass of the oxygen in this molecule. Percent composition will be:

Molar mass Oxygen / molar mass Fe(OH)3 * 100

Molar mass Fe(OH)3 and oxygen:

1Fe = 55.845g/mol*1 = 55.845

3O = 16.00g/mol*3 = 48.00 - Molar mass of Oxygen

3H = 1.008g/mol*3 = 3.024

55.845 + 48.00 + 3.024 =

106.869g/mol is molar mass of Fe(OH)3

% Composition of oxygen is:

48.00g/mol / 106.869g/mol * 100 =

Answer:

continuously changing

Explanation:

The velocity of a person on a merry-go-round can best be described as continuously changing. This is because the initial velocity before the ride starts would be 0. Once the ride begins, it keeps going faster and faster until it reaches a certain speed. During this time the velocity is increasing. Then it remains constant for a certain period of time and when the ride is over the velocity and speed begins to decrease until ultimately reaching a speed of 0. Therefore, it is continuously changing throughout the duration of the ride.

Answer:  There are 6.9 mol of [tex]F_{2}[/tex] are required to react completely with 2.30 mol of S.

Explanation:

The given reaction equation is as follows.

[tex]S(s) + 3F_{2}(g) \rightarrow SF_{6}(g)[/tex]

Here, 1 mole of S is reaction with 3 moles of [tex]F_{2}[/tex] which means 1 mole of S requires 3 moles of [tex]F_{2}[/tex].

Therefore, moles of [tex]F_{2}[/tex] required to react completely with 2.30 moles S are calculated as follows.

[tex]1 mol S = 3 mol F_{2}\\2.30 mol S = 3 mol F_{2} \times 2.30 \\= 6.9 mol F_{2}[/tex]

Thus, we can conclude that there are 6.9 mol of [tex]F_{2}[/tex] are required to react completely with 2.30 mol of S.

i think is true..

Answer:

The correct answer is - 25.

Explanation:

Given:

Sum of the 3 consecutive odd numbers = 69

solution:

Let’s assume the initial number - 2X+1

Let's say the second number is -‘2X+3’ and

Let's say the largest number is- ‘2X+5’.

Sum of the numbers = 69

(2X+1) + (2X+3) + (2X+5) = 69

6X+9 = 69

6X = 69–9

6X = 60

X = 60/6

X= 10

So, x value would be 10. Putting value of X in 2X+5

= 2(10)+5

Answer:

TRUE

Explanation:

Standard temperature is 273K and 350°C is 623K.

V/V' = T/T'

3/6.84 = 273/T'

T' = (273×6.84)/3

=> T' = 623K

So it is true.

Answer:

10.8 days (3 sig.figs.)

Explanation:

All radioactive decay is 1st order decay defined by the expression A = A₀e^-kt

which is solved for time of decay (t) => t = ln(A/A₀) / -k

A = final weight = 1.0 gram

A₀ = initial weight = 16.0 grams

k = rate constant = 0.693/t(1/2) = 0.693/2.69 days = 0.258 days⁻¹

t = ln(1/16) / -0.258da⁻¹ = (-2.77/-0.258) days = 10.74646792 days (calculator)
