Answer:

The equation of the object's velocity in time is [tex]v(t) = v_{o}\cdot e^{-\frac{k\cdot t}{m} }[/tex].

Explanation:

By Newton's Laws of Motion, the equation of motion that represents the deceleration of the object is described by:

[tex]\Sigma F = - k\cdot v = m\cdot \frac{dv}{dt}[/tex] (1)

Where:

[tex]k[/tex] - Damping constant, in newton-second per meter.

[tex]m[/tex] - Mass, in kilograms.

[tex]v[/tex] - Velocity, in meters per second.

[tex]\frac{dv}{dt}[/tex] - Acceleration, in meters per square second.

Then, we modify (1) until the following ordinary differential equation with separable variables is found:

[tex]-\frac{k}{m} \int \, dt = \int {\frac{dv}{v} }[/tex] (2)

Then, we integrate the equation and find the following solution:

[tex]-\frac{k}{m}\cdot (t-0) = \ln \frac{v}{v_{o}}[/tex]

[tex]- \frac{k\cdot t}{m} = \ln \frac{v}{v_{o}}[/tex]

Finally, we clear the velocity in the solution of the differential equation is:

[tex]v(t) = v_{o}\cdot e^{-\frac{k\cdot t}{m} }[/tex]

The equation of the object's velocity in time is [tex]v(t) = v_{o}\cdot e^{-\frac{k\cdot t}{m} }[/tex].

Answer & Explanation:

C) They used modern technology to improve prevention programs and screen travelers.

They quickly contained Ebola in a little span of 3 years. The plague lasted from December 26th, 2013 to June 9, 2016. In 2016 all cases were confirmed to be taken care of, as the majority had herd immunity. There were only 11,323 lost ones during this time period. This may sound like a lot, but, so far in our outbreak, which has lasted from December 2019 to the current time, May 19, 2021. It's not even fully cured and we're sitting on a 587,000+ count with over 33 million cases! It's been less time than the Ebola and we've managed to rise numbers in this thing. However, with the help of technology, we can find vaccines for these diseases and help people to stay safe as well.

Remember, stay safe! This vaccine is out! Make sure to get yours as soon as you possibly can, and if you don't, still stay safe! Wear your mask or just keep your distance from those you don't know. Do simple things like coughing or sneezing into your elbow or into a tissue, it helps to keep your loved ones, yourself, and the people around you safe.

One type of society that's benefits outweighs the costs is the Agricultural society.

The reason why in these agricultural societies the benefits outweigh the costs is that farmers produce crops and cattle to trade or exports, but also they can use this food for their own consumption so they can feed their families and have this necessity covered.

So today these societies can have their basic necessities covered and trade another percentage of their production to generate a profit.

Answer:

Length of arc = 21.99 inch (Approx.)

Explanation:

Given:

Radius of given circle = 6 inch

Central angle = 210°

Find:

Length of arc

Computation:

Length of arc = [θ/360][2πr]

Length of arc = [210/360][2(22/7)(6)]

Length of arc = [0.583][12(3.1428)]

Length of arc = [0.583][12(3.1428)]

Length of arc = [0.583][37.7136]

Length of arc = 21.987

Length of arc = 21.99 inch (Approx.)

A. They have different backgrounds, educations, and lifestyles.

Explanation:

A corporation can be defined as a corporate organization that has facilities and owns or controls assets used for the production of goods and services in at least one country other than its headquarter (home office) located in its home country.

This ultimately implies that, a corporation is a corporate organization that owns or controls its business in two or more countries.

Generally, a corporation is considered to be perpetual in nature and it is a body that comprises of a group of people such as directors, shareholders etc., who act as a single entity.

Sociology can be defined as a social science that deals with the study of the socio-cultural interaction of humans with respect to the structure, functioning and development of their society.

The main purpose of sociology is to develop and enhance human knowledge or understanding of important socio-cultural processes through the gathering and analysis of all aspects of the social life of the people living in a society.

A social group refers to two or more people (individuals) that shares similar characteristics, interacts with one another based on mutual understanding and expectations while collectively possessing a sense of unity.

This ultimately implies, a social group share a common identity, sense of unity and backgrounds.

Hence, employees of a big corporation are not considered a social group because they have different backgrounds, educations, and lifestyles.

Answer:  A.) They have different backgrounds, educations, and lifestyles.

Brown water is Minerals, sediment, or rust that accumulates in the water mains over time is the cause of brown or discolored water. And is not good to use for drinking and/or washing clothing. But, it is okay to shower in and use in toilets.

That makes BROWN WATER an incorrect answer.

Groundwater is used for many things such as watering plants, and drinking water for 99% of rural areas. Groundwater is not used in washing machines but many people are trying to revert to groundwater for sewage.

That makes GROUNDWATER an incorrect answer.

Ethanol is used for drinks, paint, caned fruit and sugar.

That makes ETHANOL an incorrect answer.

Black water is waste water from bathrooms and toilets that contains faecal matter and urine.

That makes BLACKWATER an incorrect answer.

Grey water is used for washing but not sewage.

P(R I Q) = P(RnQ) / P(Q) = 0.1 Therefore P(RnQ) = 0.1 X 0.35 = 0.035 (The intersection in the centre of a Venn Diagram)

P(RnQ') = 0.15 In a Venn Diagram this is R but excluding the centre intersection with Q. Therefore P(R) = P(RnQ') + P(RnQ) = 0.15 + 0.035 = 0.185

P(RUQ) = 0.15 + 0.035 + 0.315 = 0.5 so 0.5 must be outside the Venn Diagram circles.

3. The transatlantic slave system had tremendous effects on the peoples of the Americas, Europe, and Africa.

Develop an argument that evaluates the extent to which the transatlantic slave system affected culture during the period from ca. 1450 to 1750 CE.

Explanation:

In Africa, the slave trade had disastrous consequences. Rebel groups and tribal groups who benefited financially from the slave trade created an environment of anarchy and brutality. Throughout much of west Asia, population reduction and a persistent fear of imprisonment caused severe economic growth nearly impossible.

Women during the pregnancy period and men who would usually be starting families made up a significant number of those kidnapped in Africa. People who were old, disabled, or otherwise completely reliant who may have been less able to participate to their communities' health of the economy were often left behind by European slave owners.

Many people, businesses, and countries benefited greatly from the atlantic slave trade. However the brutal human trafficking and huge amount of deaths that resulted ultimately ignited well structured resistance to the trade.The slavery was abolished by the British in 1807. Imprisoned citizens in Former colonies were liberated by another legislation enacted in 1833.

In 1808 Congress passed a law prohibiting the spread of slavery into the U. S. Though the law passed it not end slavery completely.  Other nations, including Spain, Netherlands, Sweden, and France, had enacted legislation prohibiting the expansion of slavery by the 1820s.

However, since there was still a large market for enslaved people and money to be made from trading in them, such legislation did not necessarily put an end to slavery. The atlantic abolition of slavery was eventually abolished in the late 1800s thanks to new legislation and continuing protection measures.

Answer:

Structure; protein molecules.

Explanation:

In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.

Basically, the normal blood pH of a human being should be between 7.35 and 7.45.

Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.

For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.

The structural formula or dimension of a protein and its relationship (interaction) with other protein molecules generally determine the function of a protein.

Simply stated, the function of a protein is largely dependent on its structure and the level of interaction with other protein molecules.
