A girl stands on a bathroom scale. In metric units, the scale indicates that her weight is 42

Newtons. This means the force of gravity is pulling her feet onto the scale with a force of 42

Newtons. With what force does the scale push back up against her feet?

Answers

Answer:

The bathroom scale pushes her back 42 metric units, the same as her weight. Newton's 3rd law says that how much ever you push onto some object, it pushes back onto you with that same amount of pressure.

Complete the sentences to identify the difference between a nonmetal atom and its anion.


In an anion, there are more *blank* than *blank*, giving the anion a *blank* charge.

In nonmetal atoms, the number of *blank* and *blank* are the same and there is a *blank* charge.


key bank:

- a positive

- no net

- electrons

- protons

- a negative

- neutrons

Answers

Answer:

more protons than neutrons and the number of electrons  and blank are blank

Explanation:

The complete sentences that distinguish the difference between a nonmetal atom and its anion are as follows:

In an anion, there are more electrons than protons, giving the anion a negative charge. In nonmetal atoms, the number of protons and neutrons are the same and there is a negative charge.

What are Non-metals?

Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.

In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.

The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.

Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.

Answers

Answer:

Mixture

Explanation:

When a prospector scoops up part of the stream bed, the pan contains stream sediments.

The term that best describes what is in his pan when he scoops up part of the stream bed is the mixture. Thus, the correct option for this question is A.

What is a Stream bed?

A stream bed may be defined as the strait extremity of a stream or river through which the physical confine of the normal water flow. It is a type of channel significantly occupied by a stream.

According to the context of this question, when a prospector scoops up part of the stream bed, the pan contains stream sediments, which implies that the mixture contains stream sediments or contamination.

Therefore, the mixture is the term that best describes what is in his pan when he scoops up part of the stream bed. Thus, the correct option for this question is A.

Answers

Answer:The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion: diffusion is the movement of molecules of a substance from one position to another.

Explanation:

Option A is correct. The statement that best describes the motion of  the dye molecules in the water is "the dye molecules move in a directed way from high to low".

The motion of dye molecules in water is known to be random. Another name for random motion is Brownian motion and since diffusion is also Brownian motion, hence we can term the motion of the dye molecules in the water as "diffusion".

The water is held together by intermolecular forces and these forces are the ones that attract the molecules of the die carrying them away and making the process of molecular transport of the dye to be accelerated (moving from a region of high concentration to low concentration).

In conclusion, the statement best describes the motion of  the dye molecules in the water is "the dye molecules move in a directed way from high to low".
