The table shows the brightness of some stars when viewed from Earth. The brighter a star appears from Earth, the lower its apparent magnitude value is in the table. Star Apparent Magnitude Sun -26.8 Arcturus -0.06 Sirius -1.47 Vega 0.04 Betelgeuse 0.41 Polaris 2.0 Why does the sun appear so much brighter than the other stars listed in the table?

Answer:

4.52*10^23 atoms in 2.5 moles of carbon.

Explanation:

multiply 2.50 mol CO2 by 3 atoms/1 mol CO2 before multiplying by 6.022*10^23 atoms/1mol atoms.

In 2.5 moles of Carbon (C) there are 12.53‬^23 atoms. This is arrived at by utilizing Avogadro's number.

Mole is short for molecules. Molecules are a combination of atoms.

To derive the number of atoms in 2.5 molecules of carbon, we need to divide it's weight in grams with the atom mass units.

To get the atomic mass units (amu) we need to check the periodic table.

Once the division is done, the result must be multiplied by Avogadro's number which is stated as 6.02 x 10^23.

Thus, the formula is given as:

amu = grams/mole; or

u = g/mole

Since the Molar Mass of Carbon is 12.01g/mol

The number of atoms will be

2.5/12.01 X  6.02 x 10^23.

= 0.20815986677768526228143213988343‬ x 6.02 x 10^23.

=  1.2531223980016652789342214820983‬ x 10^23.

= 12.531223980016652789342214820983‬^23.

≈ 12.53‬^23.

It is to be noted that the molar mass of carbon is derived from the Periodic Table.

Answer:

Millions of animals are killed by plastics every year, from birds to fish to other marine organisms. Nearly 700 species, including endangered ones, are known to have been affected by plastics. Nearly every species of seabird eats plastics. Most of the deaths to animals are caused by entanglement or starvation.

Explanation:

Answer:

Plastic pollutes our oceans and destroys animals habits. This is a massive problem as sea animals eat plastic thinking its food, they eat it and think they're full up however they are still hungry and die of starvation. To help we can stop using plastic and use paper bags instead of plastic bag.

The correct answer is C. Reading and literacy rates, health care facilities, and gross domestic product.

Explanation

The Human Development Index is a measure that summarizes human development in a given country from three basic aspects that are:

Life expectancy, which is summarized as having a long and healthy life from the moment you are born; The level of literacy, is the knowledge that is measured from the adult literacy rate and the combination of the gross enrollment rates of primary, secondary and tertiary; the last indicator is the country's GDP per capita. Therefore, the correct answer is C. Reading and literacy rates, health care facilities, and gross domestic product

Answer:

Metamorphic rocks (from the Greek meta, change, and morphe, form, "change of shape") result from the transformation of pre-existing rocks that have undergone structural and mineralogical adjustments under certain physical or chemical conditions, or a combination of both, such as the temperature, pressure and / or chemical activity of the fluids agents of metamorphism These adjustments, imposed exclusively under the surface, transform the original rock without losing its solid state, generating a metamorphic rock. The rock generated depends on the composition and texture of the original rock, the agents of metamorphism, as well as the time in which the original rock was subjected to the effects of the so-called metamorphic process. Due to the nature of their origin, there may be a complete gradation between metamorphic rocks and the igneous or sedimentary rocks from which they were formed. The study of these rocks provides very valuable information about the geological events that occurred within the Earth and about their variation through time.

Explanation:

To classify a metamorphic rock, the type of metamorphism involved must be known, which can be variable since it depends on the criteria that are taken as a basis to differentiate it: it can be classified from the point of view of extension, fit and cause , geological value, increase or decrease in temperature, etc., but it is very common to define three main types of metamorphism according to the predominant metamorphic agent: Regional, Contact and Dynamic.

This question is incomplete because the options are missing, here is the complete question:

In North Florida, there are concerns that groundwater withdrawals to meet regional water use demands are negatively affecting the volume of water available for natural spring systems, considered a unique and significant regional environmental resource. This complex situation creates a significant ethical dilemma. Common ethical theories were discussed in the textbook readings and outlined in the lectures. Select the pair of theories that would best apply to this ethical dilemma:

Utilitarianism approach and common good approach

Utilitarianism approach and rights approach

Fairness/justice approach and virtue approach

Rights approach and virtue approach

The correct answer is the Utilitarism approach and common good approach

Explanation:

Both utilitarianism and the common good approach focus on the ethical aspects of actions. In the case of the first approach, this emphasizes the consequences of an action by analyzing the benefits or harm related to this. This approach is effective in this ethical dilemma because it is necessary to consider both the benefits for humans that will obtain fresh water and the harm in the natural ecosystem.

On the other hand, the common good approach states any individual good including access to water is linked to the general good. In the ethical dilemma presented this implies the use of water for human society is not ethical except if it leads to a general good, which includes access to water for other species living in natural ecosystems. According to this, these two approaches or theories are the most appropriate for this dilemma.
