Acid rain is of particular interest to study because it demonstrates the areas of geographical locations which are highly susceptible to pollution and scientists are able to reveal some valid conclusions.
What is Acid rain?Acid rain may be defined as the type of rain that significantly contains an excess amount of acids. The rain becomes acidic because of carbon dioxide, nitrogen dioxide, and sulfur dioxide when liberated into the air as pollutants. All these liberated compounds dissolve with raindrops in order to form carbonic acid, nitric acid, and sulphuric acid respectively.
Acid rain thus formed is very harmful as it destroys organisms and other objects on which it falls. It also destroys aquatic life, soil properties, crop productivity, etc. Acid rain reacts with marble and gradually corrodes it.
The overall concentration of acid rain at a particular location illustrates its degree of pollution, impurities in the environment, etc.
Therefore, acid rain demonstrates how much an area is susceptible to pollution. It also delivers a good concept for scientists to check it.

A balloon is inflated such that a radius is 7 cm what is the volume of air inside the balloon in milliliters
Answer:
[tex]V=14373.33\ \text{mm}^3[/tex]
Explanation:
It is given that,
The radius of the inflated balloon is 7 cm.
We need to find the volume of air inside the balloon in milliliters.
The balloon is in the shape of a sphere whose volume is given by :
[tex]V=\dfrac{4}{3}\pi r^3\\\\\text{Put r = 7 cm}\\\\V=\dfrac{4}{3}\times \dfrac{22}{7}\times 7\times 7\times 7\\\\V=1437.33\ \text{cm}^3\\\\\text{We know that, 1 cm = 10 mm}\\\\\text{So},\\\\V=14373.33\ \text{mm}^3[/tex]
Hence, the volume of the air inside the balloon is [tex]14373.33\ \text{mm}^3[/tex].

More of the radioactivity is lost during the fourth half-life than in the first half-life. Isotopes are the most stable during the first half-life. Isotopes are the least stable during the later half-lives.
Answer:
Yes, A.) "More of the radioactivity is lost during the first half-life than in later half-lives." is the correct answer!!
Explanation:
I took the practice test on edge
More of the radioactivity is lost during the first half-life than in later half-lives describes radioactive decay of a substance.Hence, Option (A) is Correct.
What is Radioactive Decay ?
Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation.
A material containing unstable nuclei is considered radioactive.
Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles.
Therefore, More of the radioactivity is lost during the first half-life than in later half-lives describes radioactive decay of a substance.Hence, Option (A) is Correct.

how does the hill Height affect the speed in there for the energy of a roller coaster
Answer:
the higher the hill the faster it'll be when coming down it. if going up the hill then the speed will be slower
Explanation:
Answer:
There are 2 types of energy - kinetic and potential. Potential energy is built up, while kinetic energy is released. As the roller coaster goes higher, it pulls further away from gravity. As it goes down, it accelerates (Gains speed). The KINETIC ENERGY in the roller coaster grows as it goes down.

What is mass?Mass is the quantity of matter. It calculates the inertia of the body. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force. The change caused by an applied force is smaller the more mass a body has.
The mass of a body is the same everywhere, but the weight changes in different places due to gravity. The force of gravity is different in different places, so the weight changes.
That's, why the mass measurement does not include the effect of Earth's gravitational pull on the object. It's the weight.
Thus, the correct options are 16. false, 17. false, 18. true, 19. true, and 20. false.

Which statement best explains why water has a higher boiling point than ethane?
Ethane molecules are smaller than water and can move faster.
Water molecules need relatively less heat energy to move.
Water molecules form hydrogen bonds, which cannot be broken by heating water.
Ethane molecules have no hydrogen bonds and need less energy to separate.
Answer:
Ethane molecules have no hydrogen bonds and need less energy to separate.
Explanation:
Ethane: has no hydrogen bonding, it has low melting, boiling points, and is a gas at room temperature.
Water: has strong hydrogen bonding between H and O, has relatively high melting and boiling points.
Statement that explains the relationship between boiling point of water and ethane and how the boiling point of water is higher than ethane is D:Ethane molecules have no hydrogen bonds and need less energy to separate.
The boiling point of water is usually high compare to that of ethane because of the hydrogen bonds present in water which is a electromagnetic attraction between hydrogen atom electronegative atom of Oxygen.And which this requires so much energy to break unlike ethane that doesn't contain any hydrogen bond.
Therefore, option D is correct.
