Answer:

The six-row combin harvests 285 bushels of corn per hour.

Explanation:

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them. That is, what is intended with it is to find the fourth term of a proportion knowing the other three.

If the relationship between the magnitudes is direct, you can apply the following formula:

a ⇒ b

c ⇒ x

So: [tex]x=\frac{a*b}{c}[/tex]

In this case you can apply it in the following way: if 56 pounds is equal to 1 bushel, 266 pounds to how many bushels is it?

[tex]x=\frac{266 pounds*1 bushel}{56 pounds}[/tex]

x=4.75

This is, a six row combin harvests 4.75 bushels of corn per min.

So, being 1 hour equal to 60 minutes, you can apply the following rule of three: if in 1 minute a six-row harvester harvests , in 60 minutes how many bushels of corn it harvests?

[tex]bushels of corn=\frac{60 minutes*4.75 bushels of corn}{1minute}[/tex]

bushels of corn=  285

The six-row combin harvests 285 bushels of corn per hour.

Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.

Answer:

90.10 g

Explanation:

Step 1: Given data

Number of molecules of water: 3.011 × 10²⁴ molecules

Step 2: Calculate the moles corresponding to 3.011 × 10²⁴ molecules of water

We will use Avogadro's number: there are 6.022 × 10²³ molecules of water in 1 mole of molecules of water.

3.011 × 10²⁴ molecules × (1 mol/6.022 × 10²³ molecules) = 5.000 mol

Step 3: Calculate the mass corresponding to 5.000 moles of water

The molar mass of water is 18.02 g/mol.

5.000 mol × 18.02 g/mol = 90.10 g

Explanation:

It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131

Heavy unstable atoms will continuously emit radiation and will undergo nuclear decay to form stable products. 25 g of americium -241 will take 39 years to decay into its 6.25 g sample.

Heavy unstable nuclei undergo decay when they emit radiations of alpha, beta or gamma particles. After that they will form stable isotopes or other lighter nuclei after emitting these charged particles.

The time an unstable nuclei takes to decay into half of its initial amount is called half life time. The half life time of Americium -241 is 432 years. Thus half life time of 25 g of Am-241 is

= (25 × 432 )/241

= 44.81 years.

The decay constant k can be calculated as follows:

k = 0.693 /half life time

  = 0.693 /44.81 yrs

 = 0.015.

Now the time taken for the decay process is calculated by the following  equation:

t = 1/k log (25/6.25)

 = 1/0.015yr-1  log (25/6.25)

 = 39 years

Hence, 5 g of americium -241 will take 39 years to decay into its 6.25 g sample.

An orbital is a region in space where there is a high probability of finding an electron.

In an atom there are orbitals. Orbitals are mathematical probability functions that describe regions in space where an electron could be found according to the wave mechanical model of the atom.

In the 3p sublevel, there are three orbitals. In the 2s sublevel, there is only one orbital. In the 4f sublevel, there are seven orbitals. In the 5d sublevel, there are five orbitals. In the third principal level, there are three nine orbitals in the fifth energy level, there are 25 orbitals.

The answer would be: Making fluorescent light for houses.

Making fluorescent lights for houses can be categorized as use of plasma in technology.

Plasma technology is commonly used in many industries, including in the automotive, microelectronics, packaging and medical device industries. Along with solid, liquid and gas, plasma is a state of matter.

State changes occur by either adding or removing energy from a substance.

Making fluorescent lights for houses can be categorized as use of plasma in technology

The mercury atoms in the plasma generate light very efficiently, but much of it is ultra-violet (UV), invisible to the eye and harmful to it (or rather, it would be, were it not absorbed by the glass).

The solution is to coat the inside of the tube with a glow-in-the-dark (fluorescent) paint, which absorbs the UV and re-emits its energy as visible light.

Therefore Option C is the correct answer.

55 kilometers per hour to meters per second

First we have to convert the kilometers to grams;

1 kilometer = 1,000 meters

This means we have;

55000 meters per hour

Converting hour to seconds;

1 hour = 60 minutes

1 minute = 60 seconds

1 hour = 60 * 60 = 3600 seconds

We divide 55000 by 3600;

55000 / 3600 = 15.28 meters per second

Answer:

C) The boss wants to know who can take the late shift tonight, who can open tomorrow morning, and who can work on the holiday.

Explanation:

The sentence that has been in the parallel structure has been the boss wants to know who can take the late shift tonight, who can open tomorrow morning, and who can work on the holiday has been in parallel structure. Thus, option C is correct.

The parallel structure can be defined as the continuous repetition of the grammatical form in the sentence. The parallel structure has been able to provide equal importance to the tasks in the sentence.

In the given sentence, the varying task has been late shifts, open tomorrow, and work on holidays. The grammatical form of who can has been able to give equal importance to every task with the repetition.

Thus, boss wants to know who can take the late shift tonight, who can open tomorrow morning, and who can work on the holiday has been in parallel structure. Thus, option C is correct.

D because that’s the only one that makes sense

Pure substances typically only include one type of atom or molecule and are homogeneous in nature. The majority of these chemicals have a consistent or homogeneous makeup. Thus, option C is correct.

Elements are pure compounds that cannot be chemically broken down into less complex ones. Iron, gold, sulfur, oxygen, and oxygen are some well-known elements.

Because it cannot be converted into a more basic substance, an element is an example of a pure substance. Examples of pure substances include water, neon, and sodium chloride (NaCl) (table salt).

One element or a few related compounds make up pure substances. A kind of matter with a predictable chemical composition and physical properties is referred to as a chemical substance.

Homogeneous mixes are made up of two or more components or compounds that cannot be seen separately from one another.

Therefore, a single element or compound show properties of pure substance.

The primary reason that large numbers of people left Ireland in the 1840s and 1850s was MASS STARVATION.

Great Famine or Great Hunger was a period in Ireland where mass starvation, diseases, and emigration occurred between 1845 to 1852.

The Great Famine was caused by Phytophthora infestans, a disease that infests in potatoes. Though the potato infestation spread throughout Europe, it greatly affected Ireland, where 1/3 of its population was dependent on the potato crop as their primary source of food.

The loss of their primary source of food led to mass starvation, sickness, and eventual death. Others opted to leave Ireland and seek shelter and food in other countries to survive.

Answer:

Hydrogen

Explanation:

Hydrogen has only 1 proton and has an atomic mass of 1. It does not have neutrons. Helium and above have higher mass than Hydrogen.

According to the electronic configuration, element with lowest atomic mass is hydrogen.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
