The diagrams below show the same set of energy levels as in Parts A and B, but with a different set of electron transitions (notice that the arrows are now different). Assuming that these electron transitions were caused by the absorption of a photon, rank the atoms based on the energy of the absorbed photon, from highest to lowest.
Answers
-arrow pointing down to the right, from center to outside of circle
-arrow pointing up right, from center to second to outer circle
-arrow pointing straight down, from center to inner circle
-small arrow pointing up right, from inner circle (not center) to outer circle
Lowest energy
The atom in which the electron leaves (the atom is ionized) corresponds with the highest-energy photon, and the atom with the shortest arrow indicates the case where the absorbed photon had the lowest energy.

What is a scientific investigation?A plan for raising questions and putting potential solutions to the test is scientific research. Observations are frequently the first step in scientific research. Questions frequently follow observations.
A hypothesis is a potential explanation for a scientific question based on current scientific understanding.
Making conjectures (hypothetical explanations) is a step in the scientific method. Predictions are then derived from the hypotheses as logical conclusions, and experiments or actual observations are conducted based on those predictions.
Therefore, the correct option is D. this ensures that all variables have full reliability and validity.

Of the three types of subatomic particles, only neutrons do not carry charge. Protons carry a positive charge, and electrons carry a negative charge. Protons and neutrons are bound in the nucleus, while electrons orbit the nucleus. When the number of each type of subatomic particle in an atom changes, the characteristics defining the atom also change. Match the appropriate phrases with the type of subatomic particle that completes the defining characteristic.
Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer.

2. The number of PROTONS identifies the type of element.
The number of each type of subatomic particle plays an important role in the characteristics of the atom. The general element classification (hydrogen, carbon, oxygen, etc.) is governed by the number of protons in the nucleus. If the number of protons changes in an atom, so does the type of element. The electrons are the only type of subatomic particle not in the nucleus. They orbit around the nucleus, bound by the electromagnetic force. When electrons are lost or gained by a neutral atom, the charge balance shifts, resulting in the atom becoming an ion. Ions can be either positive when electrons are lost or negative when electrons are gained.

(First image) The Bohr model accounted for most of the general characteristics of the atom. However, the modern model based on quantum mechanics explains that, although the energy of each orbital is fixed, the orbital radius is actually an average distance. The result is a "cloud" where the electron would most probably be located.
When electrons are excited to different energy levels, the average radii from the nucleus also changes. Rank the following electron energy states according to the average distance of the electron from the nucleus. Rank from largest to smallest distances.
Answers
- third excited state
- second excited state
- first excited state
- ground state
Smallest distance
Excited states refer to the energy state of an electron. The higher the state, the higher the energy and the greater the distance of the electron from the nucleus. Due to the attractive force between the negatively charged electron and the positively charged nucleus, the electron requires greater energies to overcome this attraction and achieve orbits at greater distances.

Do you think government should provide easily accessible loans to students? What are some of the secondary effects of doing so?
Answers
Answer:
Below
Explanation:
If the government were to provide easily accessible loans to students, then there would likely be more students going to college, which would be a good thing because we would have a more educated society and workforce. However, taxes would have to be raised in order for people to receive these loans. There also would be a high percentage of the population in debt. Those would be the secondary effects.

Due to changes in the tax structure and stagnant wages over the past fifty years, the income inequalities between the top and lowest earnings in the United States have significantly widened.
What is meant by the income gap?
An income gap is a term used to describe the disparity in income between demographic groups. The average income shortfall of families or people with incomes below the poverty line, represented as a percentage of the poverty line.
Numerous factors contribute to income inequality, such as historical racial segregation, political policies, a stagnant minimum wage, outsourcing, globalization, technological advancements, and the declining influence of labor unions.
What is the income inequality gap in the United States?
The wealth of the United States was owned by the wealthiest 10% of citizens in 2021, up from roughly 61 percent at the end of 1989. Over that time, the share held by the bottom 40 percent decreased proportionally. In 2021, the bottom 50% of the population, or around 63 million families, possessed 2.5% of the total wealth.

Answer:
Let understand that "Weightlifting" is a section of sport which involves individuals lifting heavy weight from the floor to shoulder position, back position and so on.
In essence, Weightlifting are used to build muscle and strengthens the bones & joints but also, the idea are passed as sport to see the ability of sportsmen in lifting heavy weight.
Some of the erroneous ideas about weightlifting are:
Lifting weights leads to bulking up: This idea is false and bulking up of muscles is determined by intake of calories to build the muscle internally. Weightlifting only make the muscles firm.
That weightlifting is bad for the joints: This idea is erroneous and not can not be proved. This exercise aids increased range of motion of the joint and thus ensure flexibility.
