what kind of state is a roller coasters are the best use of Newton's laws of motion​

Answers

I am slightly unsure on the question, but if you are asking what kind of "statement" is "roller coasters are the best use of Newton's laws of motion​" then the following should answer your question:

Answer:  

An opinion.

Explanation:  

          In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.  

          The statement, "Roller coasters are the best use of Newton's laws of motions" is an opinion because it is not based on any evidence, facts, or proof to back it up.

why do atoms emit light energy according to the bohr model?

Answers

Answer: According to the Bohr model, atoms emit light because excited electrons are returning to lower energy states, emitting the energy difference. This energy always has a specific wavelength because the electrons can only exist in set orbits. ... An emission spectrum is the frequencies of light emitted from an atom.

Explanation:

Atoms emit light energy because electrons transit between energy levels by absorbing energy and relaxing by emission of radiation.

What is Bohr's model of atom?

According to Bohr model of atom the electrons are revolving around the nucleus through the circular paths of fixed energies. These circular paths are called orbits.

Using this model the momentum and velocity of an electron  and the atomic radius can be determined. Bohr, states the electrons are able to transit between these energy level and the energy difference between the two energy levels will be equal to the energy of a photo  absorbed by the atom.

Electrons excite to higher energy level by by absorbing energy and they cant stay there for long while and relax back to the ground state by emitting a the radiation which is complementary wavelength to the absorbed one. That's why the atoms emit light.

Oil is less dense than water. What happens when you mix the two liquids together?

(A) Oil sinks to the bottom of the container.
(B) The two become one smooth mixture.
(C) The oil floats on top of the water.
(D) The water turns to gas inside the oil.

Answers

Answer:

(C) The oil floats on top of the water

Explanation:

If an object/substance is less dense than water it will float on the water.

If an object/substance has the same density as water it will stay submerged in the water, but will not sink to bottom.

If an object/substance is more dense than the water it will sink to the bottom.

Using the periodic table, explain which pair of the following gases have the most similar properties and why. Nitrogen (N), Fluorine (F), Neon (Ne), Krypton (Kr), and Oxygen (O).

Answers

Answer:  Neon (Ne) and Krypton (Kr)

Explanation:

Elements that belong to the same group of the periodic table (column) have similar properties. This is because elements of the same group have the same amount of valence electrons. This means that chemically and especially in a chemical reaction (or lack thereof), they will behave similarly.

Neon and Krypton are the only two gases in the list given that belong to the same group of the periodic table (Group 18 - Noble Gases) and as such have similar properties.

Similar Properties of Neon and Krypton:

- Both have 8 valence electrons - They both are very stable and almost unreactive- Both are gases at RTP-Both are odorless, colorless, and tasteless until interaction with an electrical charge.
