The first box would be the pH will decrease, and the acidity will increase, and for the second box, the pH will increase, and the acidity will go down.

Explanation:

As the hydronium concentration increases, the pH decreases, and therefore if the hydromnium concentration decreases, the pH will increase. pH is sort of backwards, as the level increases, the acidity will go down, and as it decreases, the acidity will go up.

when the concentration of hydronium ions increase, the pH level decreases. because the pH is decreasing, the acidity is increasing (as anything below a 7 on the pH scale is acidic)

when the concentration decreases, the pH level increases, therefore causing it to become more basic/alkaline (acidity decreases)

Choose the words or phrases that correctly complete the sentence. Two boys are holding onto the ends of a long piece of string, and they move it up and down to make a wave. They begin to move the string faster and faster. When they move the string, the energy (remains the same / increases / decreases) and the frequency (decreases / increases / remains the same). Group of answer choices increases, increases remains the same, remains the same decreases, decreases increases, decreases

Answers

energy increases frequency decreases :)

When two boys move the string, the energy increases, and the frequency increases. Thus, the correct option for this question is A.

How are energy and frequency of waves related to one another?

The energy and frequency of waves are always directly related to one another. It means that when energy increases, frequency increases. When energy decreases, the frequency decreases.

Now, according to the context of this question, when two boys begin to move the string faster and faster, the energy gradually increases with an increase in frequency as they both are directly related to one another.

Therefore, when two boys move the string, the energy increases, and the frequency increases. Thus, the correct option for this question is A.

Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to her ability to exercise?

A: it would be harder for her to exercise because her digestive system would need to use more enzymes to combine the glucose molecules together.

B It would be easier for her to exercise because glucose moves through the circulatory system faster than other food molecules usually do.

C Nothing would happen to her ability to exercise, but her respiratory system would not work as hard, since glucose has more energy than oxygen molecules.

D Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Answers

Answer:

D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Explanation:

According to this question, some types of syrup contains an entirety of glucose molecules. Hence, eating a syrup like this will have no effect on the person's ability to exercise, however, since glucose is the simplest unit of carbohydrate food sources, it gets digested easily.

Originally, glucose molecules, which are products of digestion, enter into our cells to be used to synthesize energy. However, for a syrup already made up of glucose molecules, the digestive system would not work as hard, since glucose is already small enough to get to her cells.

Glucose is the simplest form of carbohydrate, which is digested by the human digestive system. The syrups that are completely made of glucose molecules will not affect the person's ability to exercise.

The correct option is:

Option D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.

Glucose is the primary source of energy in all living organisms.

If a person is consuming a syrup made up of glucose molecules, it will not affect the ability of a person to exercise.

The glucose is present in simpler form, which will be directly absorbed by the cells to carry out functions and yield energy.

Thus, the digestive system will work normally because the cells are supplied with glucose and it won't affect the ability of the person to exercise.

Therefore, option D is correct.

One side of the water molecule has a positive charge, while the other side has a negative charge. What do the charges indicate about the molecule?

Answers

Answer:

That its a nuetral

Explanation:

In the given case of water molecule, the charges shows that it is a polar molecule.

What is a polar molecule?

It is a molecule in which one terminal of the molecule is slightly positive and the other terminal is slightly negative. In the case of water molecule, the unequal sharing of electrons provides the molecule with a slight negative charge close to its oxygen atom and a slight positive charge close to its hydrogen atoms.

When a neutral molecule, possesses a positive region at one terminal and a negative region at the other, it is considered as a polar molecule. The molecules of water attract each other on the basis of the positive end of one water molecule and the negative end of the other molecule of water.

Thus, the charges shows that it is a polar molecule.

What is the distance and the displacement of the race car drivers in the
Indy 500?*
A.0m,0m
B.500m,500 m north
C.500m, 0m

Answers

Answer:

Distance is 500 m and displacement is 0.

Explanation:

Distance traveled by an object is equal to the total path covered during the entire journey. Displacement of an object is the shortest path covered.

In this case, we need to find the distance and the displacement of the race car drivers in the  Indy 500 m race in a circular path.

In a race, the object must reach the initial position after some time. It means that the final and the initial position is the same. As a result, the shortest path covered i.e. displacement of the car is equal to 0. On the other hand, total traveled distance is 500 m.

Which effect does the sun's energy have on a comet?
A. It causes the comet to form a bright tail.
B. It causes the core of the comet to melt.
C. It causes the comet to turn toward earth.
D. It causes the comet to break apart.

Answers

Answer:

The answer is B because the sun melts the core of the comet

The sun's energy causes the comet to form a bright tail. The correct answer is A.

When a comet approaches the Sun, the Sun's energy causes various effects on the comet.

As the Sun heats up the comet, it causes the icy nucleus of the comet to vaporize and release gas and dust into space.

This process is known as outgassing. The released gas and dust form a glowing envelope called a coma around the nucleus.

Additionally, solar radiation and solar wind push the released gas and dust away from the comet, forming a glowing tail that points away from the Sun.

So, the correct option is A.
