A medium-temperature star like the Sun would most likely emit its most intense radiation as _____. A. Ultraviolet light B. Visible light C. Microwaves D. Radio waves

Answers

Answer:

The correct answer is option B, that is, visible light.

Explanation:

The Sun is a prime source of ultraviolet rays. Although the Sun discharges all of the distinct types of electromagnetic radiation, 99 percent of its rays are in the form of ultraviolet rays, visible light, and infrared rays. The Sun emits radiation all through the electromagnetic spectrum, that is, from extremely high-energy X-rays to ultra-lengthy wavelength radio waves, and everything that comes in between. However, the peak of the emission takes place in the visible part of the spectrum.

What is the correct way to represent 5600 L using scientific notation?–5.6 mc031-1.jpg 103 L
–5.6 mc031-2.jpg 10–3 L
5.6 mc031-3.jpg 10–3 L
5.6 mc031-4.jpg 103 L

Answers

To answer this you first must know that the value before the x10^n must be below 10 and equal or greater than 1. All the choices are valid with respect to this law. Next, 5600L is positive canceling the first 2 choices. The last value is the answer since multiplying a value with 10^3 makes a larger number or moves the decimal place to the right 3 places.

The correct way to represent 5600 L using scientific notation is written as 5.6 x 10³ L.

What is Scientific notation?

Scientific notation or standard form is method of representing large numbers in more condensed form using power of ten.

The correct way to represent 5600 L using scientific notation is written as follows;

5600 L = 5.6 x 10³ L

Thus, the correct way to represent 5600 L using scientific notation is written as 5.6 x 10³ L.

A major disadvantage of a corporation is thea. difficulty in transferring ownership.
b. limited life.
c. difficulty in raising capital.
d. double taxation of the corporation s income and of dividends paid to shareholders.

Answers

A major disadvantage of a corporation is the double taxation of the corporation's income and of dividends paid to shareholders.
Corporations end up paying taxes twice. The corporation pays tax when it shows a profit. Secondly the corporation pays tax when it pays out dividends to its shareholders. Sole proprietorships and partnerships are taxed as owners of the business. The owners of a corporation are taxed individually from the corporation. The advantage of this is that the owners of a corporation are not taxed on the corporation's profit.

Final answer:

Option D. A major disadvantage of a corporation is double taxation of the corporation's income and dividends paid to shareholders.

Explanation:

A major disadvantage of a corporation is the double taxation of the corporation's income and dividends paid to shareholders. This means that not only is the corporation subject to income tax on its profits but the dividends distributed to shareholders are also taxed as the shareholders' personal income. This results in a higher overall tax burden for shareholders, making it a major disadvantage of a corporation.

Which reaction occurs when hydrogen ions react with hydroxide ions to form water?A. substitution
B. saponification
C. ionization
D. neutralization

Answers

Answer: D. neutralization

Explanation:

1. Substitution reaction is defined as the reaction in which one atom replaces the other atom from the compound.

$AB+C\rightarrow AC+B$

2. Saponification is a reaction in which fatty acids are made to react with alkalis to form sodium salt of fatty acids called as soaps.

3. Ionization is a type of chemical reaction in which a substance ionizes when dissolved in water.

$AB\rightarrow A^++B^-$

4. Neutralization is a type of chemical reaction in which an acid reacts with base to produce salt and water.

$BOH+HX\rightarrow BX+H_2O$

The answer is D.This one is a bit tricky because it requires you to realize that H+ and OH- are, respectively, an acid and a base. That's why it's neutralization.
