Which of the following descriptions explains the process of water freezing? A) Water molecules speed up until they escape into a different phase. B) Water molecules slow down until they begin to bond together C) Water molecules are squeezed together by high pressure until they begin to stick to one another. D) As water molecules cool, their shape changes from rounded to irregular, making them more likely to link to one another.

Answers

Answer:

B

Explanation:

Answer: B. Water molecules slow down until they begin to bond together

Explanation:                                                                                                                                  When the water is to be cooled, the molecules start to slow down and becomes no longer energetic which means that they are going to bond together.

Two charged particles are separated by a distance of .99m. If the charge on particle one is .00045C and the charge on particle two is .0000032C. What is the amount of force between them?

Answers

Answer:

The force between the two charges will be 13.22N.

Explanation:

The force between the two charges is given by Coulombs law which says

[tex]F = k\dfrac{Q_1Q_2}{R^2}.[/tex]

In our case

[tex]Q_1= 0.00045C[/tex],

[tex]Q_2 = 0.0000032C[/tex],

[tex]R = 0.99m[/tex].

therefore,

[tex]F = (9*10^9)\dfrac{(0.00045C)(0.0000032C)}{(0.99m)^2}.[/tex]

[tex]\boxed{F=13.22N}[/tex]

Hence, the force between the two charges will be 13.22N.

how much energy is required to move a 4.00-microcoulomb charge through a potential difference of 36.0 volts?

Answers

Answer:

1.44 X 10^-4J

Explanation:

V=w/q =605/sc=12V

The energy required to move a 4.00-micro coulomb charge through a potential difference of 36.0 volts will be 1.44 X 10⁻⁴ J.

What is the electrical potential difference?

The amount of work performed in an electrical field to move a unit charge from one location to another is defined as the electrical potential difference.

The given data in the problem is;

W is the energy =?

q is the charge = 4.00-microcoulomb

V is the potential difference = 36.0 volts

The electric potential is the ratio of electric potential energy and charge.

[tex]\rm V= \frac{W}{q} \\\\\ W=Vq \\\\ W= 36.0 \times 4.00 \times 10^{-6} \\\\ W=144 \times 10^{-6} \\\\ W=1.44 \times 10^{-4}[/tex]

Hence the energy required will be 1.44 × 10⁻⁴ J.

how many protons make an atom

Answers

Answer:

The atomic number is the number of protons in an atom of an element. In our example, krypton's atomic number is 36. This tells us that an atom of krypton has 36 protons in its nucleus.

Explanation:

Depends on what kind of atom it is. The number of protons can be seen in the periodic table as the atomic number. The number of proton within an atom is always equal to the number of electron.

In this diagram, the Moon is directly in front of the Earth. What would MOST LIKELY happen if the moon was not directly in front of the Earth? A) There would be a total solar eclipse. B) There would not be a solar eclipse. C) There would be a partial eclipse. D) There would be a lunar eclipse.

Answers

Answer: C There would be a partial eclipse.

Explanation:

Partial solar eclipses happen when the Moon comes between the Sun and Earth, but the Moon only partially covers the Sun's disk. When this occurs, the Moon, the Sun and Earth don't align in a perfectly straight line, and the Moon casts only the outer part of its shadow on Earth. This happens when only a portion of the Sun is blocked by the Moon. It occurs when the observer is within the penumbra.

Answer: C partial eclipse

If the hydroxide ion (OH-) concentration is greater than the hydronium ion (H3O+) concentration, then what is the solution?

A.
acidic

B.
basic

C.
neutral

D.
salty

Answers

If the hydroxide ion (OH-) concentration is greater than the hydronium ion (H3O+) concentration, then the nature of the solution would be basic, therefore the correct answer is option B.

What is a Chemical compound?

A chemical compound is a combination of two or more either similar or dissimilar chemical elements.

If the hydroxide ion (OH-) concentration is equal to the hydronium ion (H3O+) concentration then the nature of the solution would be neutral.

The correct response is option B because the nature of the solution would be basic if the concentration of hydroxide ions (OH-) is higher than that of hydronium ions (H3O+).

Answers

m = 600 kg
u = 0 (as the car was at rest initially)
