Shown following are the primary mirror arrangements and total light-collecting area of five different telescopes. Notice that although the arrangements look similar to those in Part B, the light-collecting areas are not the same. Also listed is an amount of time (exposure time) that each telescope will be pointed at the same distant galaxy. Again assume that the quality of these mirrors, the detectors, and the observing conditions are identical. Rank the telescopes from left to right based on the brightness of the image each telescope will take of the galaxy in the time indicated, from brightest to dimmest. To rank two (or more) telescopes as equal, drag one on top of the other(s).
Answers
A x S x B = 1/t
(since sensor speed is not mentioned consider it a constant)
B = 1/(t x A x S)
1. B = 1/(10 x 120 x S) = 1/1200S
2. B = 1/(2 x 600 x S) = 1/200S
3. B = 1/(5 x 240 x S) = 1/200S
4. B = 1/(1 x 1200 x S) = 1/200S
5. B = 1/(20 x 60 x S) = 1/200S
All of the telescopes are equal, so all of them go in the middle.

Shown following are the primary mirror arrangements and total light-collecting area of five different telescopes. Each mirror uses a different segmented arrangement, but assume that they are all equivalent in quality and in their ability to focus light. Also assume that the telescopes use identical detectors and have the same observing conditions. Rank the telescopes from left to right based on their ability to detect very dim objects, from greatest to least. To rank two (or more) telescopes as equal, drag one on top of the other(s).
Answers
(all options in the middle)
Least ability
The ability to detect the object depends on the surface area of the mirrors, given that the surface area is 100 m² for all the telescopes and the surface area for all the telescopes are equal. Hence, all the telescopes have equal ability to detect very dim objects, and all are placed in the same category.

(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.

What is a food pyramid?A food pyramid is sometimes referred to as a food chain, or pyramid of energy and it can be defined as a model that is used to depict the food chains and flow of energy from one trophic level (feeding level) to the next in a single ecosystem.
This ultimately implies that, a food chain is a pictorial diagram that compares the energy used by living organisms at each trophic level of the food pyramid.
In this scenario, we can reasonably infer and logically deduce that the value which best represents the amount of energy available for primary consumers in the food chain is 93,000 kilocalories.

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.

The atom consists of three types of subatomic particles: protons, neutrons, and electrons. The electron is by far the lightest of the three, while the much heavier proton and neutron have masses very similar to each other. Two of the types of particles carry an electrical charge, while the third is neutral. Label the subatomic particles and appropriate charges by their relative locations.
Identify the subatomic particles by dragging the appropriate labels to their respective targets.
Answers
- particle = electron
- charge = negative
left inside circle:
- particle = proton
- charge = positive
right inside circle:
- particle = neutron
- charge = neutral
This image represents the classical model of the atom proposed by Niels Bohr. Although this model has changed slightly as the result of modern scientific discoveries, it does help in understanding the relative locations of the subatomic particles in the atom. Notice that the protons and neutrons are bound in the nucleus, while the electrons are located in the space surrounding the nucleus.
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.

Match the appropriate phrases with the type of subatomic particle that completes the defining characteristic.

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.

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.
