Answer:
Explanation:
1) I personally would want to learn more about how the waves in the ocean move. About what causes high tide. What causes low tide. Why some waves are big and some small.
I know it has something to do with the gravitational pull of the moon. But that is as far as my knowledge extends on the subject. I have always been fascinated with the secrets of the ocean and the secrets of space. To me learning, this is a little of both.
2) The nature of the interaction between neutrons and protons in the atomic nucleus, which binds the nucleons together, is the biggest wonder in the inside of the atom that I would like to really know. Protons have a positive charge, but neutrons do not. What form of interaction between a charged particle and an uncharged particle is possible? That is what I expect to learn more about as a result of my explorations into the inner workings of the atom.
The inside of the atom is made up of the nucleus and electrons that travel about in orbits. The nucleus is made up of protons and neutrons. Electrons have a negative charge, protons have a positive charge, and neutrons have none. The nucleus is held together by electrostatic interaction between electrons and protons. The majority of the mass of an atom is made up of protons and neutrons.
I'm interested in finding out more about ocean waves travel. regarding the reason for high tide. what brings on a low tide. Although some waves become also large while others are smaller.
What are ocean waves?Ocean waves seem to be alterations to the ocean's surface. They could be produced by water being moved by the wind, gravity, as well as other forces.
What are waves?A disturbance that moves from one place to another across a medium has been referred to as a wave. As an illustration of a wave, think of a sinuous wave.
Personally, I'm interested in finding out more about ocean waves travel. regarding the reason for high tide. what brings on a low tide. Although some waves become also large while others are smaller I'm certain that the moon's gravitational force is somehow implicated. Because that is basically the extent of my expertise on the matter. The mysteries of the water and the mysteries of space have always interested me. I'm still learning, so this combines a bit of both.The largest enigma in the interior of the atom something I would really like to understand is the nature of the connection involving neutrons as well as protons in the nucleus of an atom, which holds the nucleons together. Neutrons just don't have a positive electrical charge, whereas protons do. What kind of interactions is conceivable between charged as well as uncharged particles. Through my investigations into the internal workings of the atom, I hope to understand more about it.

Which statement describes why sodium reacts more vigorously than magnesium to hydrochloric acid? Refer to the periodic table. Circle the letter of the correct answer.
1) Sodium has a smaller atomic radius than magnesium.
2)Sodium has a lower ionization energy than magnesium.
3)Magnesium has a lower ionization energy than sodium.
Answer:
Its B all the others arent true and also dont make any sense
Explanation:
Sodium has a lower ionization energy than magnesium describes why sodium reacts vigorously than magnesium chloride.
Why is sodium more reactive than magnesium?Sodium is more reactive than magnesium because it has the ability to easily lose electron, hence have lower ionization energy.Sodium belong to group one on the periodic table and they are called akali metal while magnesium belong to group two on the periodic table and they are called alkali Earth metal.Sodium and magnesium belong to the in the 3rd period. Iin the outermost energy level sodium has one electron but magnesium has 2 electrons. Therefore, there is more attraction abetween the nucleus and electrons in magnesium than that of sodium.Therefore, sodium is more reactive than magnesium chloride because of lower ionization energy.

How does the equation F= ma tell you that it is easier to push a small chair than a large couch
across the floor?
Explanation:
[tex] \boxed{ \mathsf{F = ma}}[/tex]
The Newton's Second law of motion, also known as The Law of mass and acceleration, derives the given equation in terms of mass, acceleration and force.
It actually states that Force applied on a body is equal to the time rate of change of it's momentum.
Momentum of a body, is the product of it's mass and velocity with which its moving.
This clarifies that objects at rest have zero momentum since they have zero velocity.
If a "source" applies force on an object, it's magnitude would depend on its rate of change of momentum with time.
Since, mass of an object is a fixed entity, so change in momentum would be caused due to change in velocity.
Now, if we happen to have two objects of different mass,
(As, in here, a chair and a large couch) and we have to push them so as to produce the same change in momentum, the force applied on a couch would be more than that applied on the chair.
Answer:This is simply because,
Force = mass × acceleration
If acceleration for both the objects is fixed, the force applied differs due to theur difference in mass.
Note here that Force I'd directly proportional to mass.
The greater the mass is, the higher is the force required to produce same acceleration.
Thus, objects with higher mass will require a greater amount of force to have the same acceleration as the object of light weight.

4. Based on your observations above, which substance needed a greater decrease in kinetic energy in order to change phase?
The substance with
(medium or low) ANSWER: Pick which one it is!
attraction needed more energy transferred out in order to change phase.
The change in phase of a substance is called a physical change. The substance C with low molecular attraction needs more energy transferred out and thus its kinetic energy have to be decreased to change from gas to liquid.
What is energy transfer?Energy can neither be created nor be destroyed. However it can be transferred from one form to the other and thus total energy of a system is conserved.
In gaseous state molecules or atoms are far apart and have minimum intermolecular forces of attraction whereas in liquid state they have medium molecular attraction and are a bit close than they are in gas state.
When a substance changes from gas state to liquid state its molecules condenses and becomes more close to each other forming higher molecular attraction.
The gas B have medium molecular attraction and thus will easily liquified with minimum energy transfer whereas, gas C is of less molecular attraction having higher kinetic energy and thus more have to transfer more energy out to liquify.

When a solid air freshener gets smaller over time and runs out is it a physical change or chemical change? please say why?
Answer:
i think this would be an example of a physical change because here the substance is changing directly from a solid to a gas without passing through the liquid state which means that the composition of the substance has not changed and remains the same. This is also called sublimation.
How is a chemical equation different from mathematical equation?
Only chemical equation uses + sign
Only chemical equation uses arrow instead of = sign
Only chemical equation has numbers
Only chemical equation has minuses
Answer:
Only chemical equation uses arrow instead of = sign
Answer:
Only chemical equation uses an arrow instead of a = sign.
A chemical equation depicts a chemical reaction by utilising chemical formulae and symbols to depict the reactants, products, and chemical changes that take place. In a chemical equation, the arrow indicates the direction of the reaction and is commonly depicted as a single arrow pointing from the reactants to the products. In contrast, the equals sign (=) is commonly used in mathematical equations to indicate that two expressions have the same value.
While numbers are used to indicate the relative proportions of reactants and products and minus signs are used to indicate reactants or products in the form of ions, the arrow is the most distinguishing feature that distinguishes chemical equations from mathematical equations.
