2. Which of the following statements about inertia is correct?
A. The more mass a body has, the more inertia it has.
B. The more mass a body has, the less inertia it has.
C. The amount of inertia a body has is not dependent upon its mass.
D. An object has to be moving to have inertia.
Please use your brain only if you know, not google or anything else :)
The statement that says the more mass a body has, the more inertia it has is correct about inertia (option A).
First, we need to recall the concept of inertia.
Inertia is the tendency of an object to oppose any change in its state. An object at rest will remain in this state until a force acts on it to move it, and vice versa, an object in motion will tend to keep the same velocity until a force acts on it to increase or slow down its speed.
Let's evaluate each statement
A. The more mass a body has, the more inertia it has.
It is true. The more body mass, the more tendency it will have to oppose the change in its state, so the force needed will be greater.
[tex] F = ma [/tex]
We can see in the above equation that the force applied is proportional to the body mass.
B. The more mass a body has, the less inertia it has.
It is false. In statement A, we said that the more body mass, the more inertia it has.
C. The amount of inertia a body has is not dependent upon its mass.
It is false. According to the inertia concept, the inertia of a body is directly proportional to its mass.
D. An object has to be moving to have inertia.
It is false. As we said above, inertia is related to a body in a state of motion as well as in a state of rest.
Therefore, statement A is correct about inertia.

How does water move between the hydrosphere and atmosphere?
Answer:
Water moves between the hydrosphere and atmosphere through evaporation condensation and precipitation.
Explanation:
Brainliest plz
Water is a renewable resource that is present in the spheres of the earth. The water moves between the hydrosphere and atmosphere through evaporation, condensation, and precipitation.
What are changing states of matter?The different matters can be changed into one another through various methods that include evaporation, condensation, and precipitation. In the water cycle, the water from the hydrosphere gets evaporated from the liquid to the vapor phase.
The evaporated water vapor then condenses and cools down to form and store in the clouds. Then the condensed vapor in the atmosphere collectively comes back to earth in the form of precipitate that can be rain, snow, sleet, hail, etc.
Therefore, the water cycle involves evaporation, condensation, and precipitation to move water between the hydrosphere and the atmosphere.

What kind of chemical bond is formed between nonmetals? Explain your answer.
Answer:
The ionic bond is formed due to an electrostatic force of attraction between two oppositely charged ions. This bond is usually formed between a metal and a nonmetal. Prior to the electrostatic attraction, there is a total transfer of valence electrons from one atom to the other atom.
Explanation: hope that helps
In general, nonmetals form covalent bonds, metals and nonmetals form ionic bonds, and metals form metallic bonds.
What are non-metals?Non-metals are natural materials that do not generate heat or electricity and are structurally brittle, making them difficult to roll, mold, extrude, or press.
Non-metallic elements in the periodic table include hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium.
Ionic compounds are formed when metals and nonmetals combine, whereas covalent compounds are formed when nonmetals combine with other nonmetals.
Metal atoms have only a few electrons in their outer shell, whereas non-metal atoms have many electrons.
This means that metals are more likely to react with nonmetals. Electrons transfer from the metal to the nonmetal when it reacts with it.
Thus, there will be covalent bonding between nonmetals.
