Activities that shows the nature and goals of anthropology,Sociology and Political Science
To answer the question effectively, we will talk about the key words in the question.
ANTHROPOLOGY, SOCIOLOGY AND POLITICAL SCIENCE.
ANTHROPOLOGY; This is the study of human kinds in all times and places,it also entails humanistic study which includes our prehistoric origins and contemporary human diversity as well as topics like social change,globalization,human origin and the world history.
The activities that shows the nature and goals of anthropology includes;
- Looking at ones own culture in a more objective way like an outsider.
- Discovering the things that make people more different from one another.
- Producing new theories and knowledge about human home and their behaviors.
- Discovering/finding out what all people have in common.
There are four fields of anthropology; Linguistic anthropology, Biological anthropology, Archeology and cultural anthropology.
SOCIOLOGY; This is the scientific study of human civilization.
It is systemic and studies of groups and societies that people build
and the effect these have on their behavior.
Sociology greatly focuses on various social connections,
structures, organizations, processes and institutions.
The activities that show the goals and nature of sociology includes;
- Broadening our familiarity on facts about sociology.
- Critically studying the nature of humanity.
- Exposing our minds to the diverse perspectives on attaining the truth.
- Obtaining possible theories about the society.
- Understanding and appreciating that all things in the society are interdependent with each other.
Sociology brings together inputs that are composed of frequent forms and manners,they include; view points, consolidated values, attitudes and the norms of social institutions.
The different branches of sociology are; social psychology,social organisation, applied sociology, population studies, sociological theory and research,human ecology,social change.
POLITICAL SCIENCE; This is a discipline in academics that deals with the study of political processes, institutions, governments and behaviors of people.
It studies the complex behaviors of the people in power, various political actors, such as the government administration, opposition ad the subjects which are the masses.
Anthropology, sociology and political science are areas of social science, whose main objective is to study society in historical, social and cultural contexts.
Anthropology is the science that studies the human being in depth considering biological, social and cultural aspects. Its objective is to understand the development of man in these aspects.Sociology has as its nature the study of societies, its objective is to understand the behavior of man in social formations.Political science is the science that studies the systems of government and formation of political power in society. Its aim is to better understand political institutions and their impact on society.Therefore, the social sciences seek to analyze and understand man through society, culture, economy and politics, with the aim of contributing to the development of a more egalitarian society with a better quality of life.

Which of the following correctly
states the difference between
elements and compounds?
Elements and compounds are the
same because they are both made of
atoms,
An element is made of two or more
types of atoms combined, while a
compound is made of one type of
stom,
An element is made of one type of
tcom, while a compound is two or
more types of stoms combined.
Answer:
An element is made of one type of atom, while a compound is two or
more types of atoms combined.
Explanation:
An element is a distinct substance that cannot be split up into simpler substances. Elements are substances that consists of only one kind of atom.
Compounds are substances composed of two or more kinds of atoms/elements joined together in a definite grouping.
There are over a hundred elements known to date. Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek Examples are copper, gold, ironThe properties of a compound are distinct and different from those of the individual elements that are combined in its make up. There are several millions of compounds known. They are usually represented by chemical formulae.As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.
You measured the mass of Coke as 21.36 grams and the volume as 20.50 ml. What is the density of Coke in
g/mL?
Answer:
The answer is 1.04 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass of coke = 21.36 g
volume = 20.5 mL
So we have
[tex]density = \frac{21.36}{20.50} \\ = 1.0419512...[/tex]
We have the final answer as
1.04 g/mLHope this helps you
Carbon dioxide is in a steel tank at 20C 10 liters and 1 atm. What is the pressure on the gas when the tank is heated to 100C?
Answer:
1.273 atm
Explanation:
We are given:
P1 = 1 atm P2 = x atm
T1 = 20 degree celsius or 293 k T2 = 100 degree celsius OR 373 k
Since the volume remains constant, we don't have to talk about that
From the Gas equation:
PV = nRT
Since number of moles (n) , Universal gas constant (R) , Volume of the gas (V) are constants
P / T = k (where k is a constant)
Hence we can say that P1 / T1 = k --------------(1)
Also, P2 / T2 = k -------------------------------------(2)
where k is the same constant
From (1) and (2):
P1 / T1 = P2 / T2
Now, plugging the values in this equation
1 / 293 = x / 373
x = 373 / 293
x = 1.273 atm
Therefore, the pressure of CO2 after increasing the temperature to 100 degree celsius is 1.273 atm

5. The sphere shown below is placed in a full overflow cup and sinks to the bottom. How much water is displaced by the sphere?
4.6 cm
O A. 51.0 ml
OB. 66.5 ml
O C. 88.6 mL
O D.407.7 ml
Answer : The correct option is (A) 51.0 mL
Explanation :
As we know that water displaced is equal to the volume of sphere.
Now we have to determine the volume of sphere.
Formula used:
Volume of sphere = [tex]\frac{4}{3}\pi r^3[/tex]
where,
r = radius of sphere
Given:
Diameter of sphere = 4.6 cm
Radius of sphere = [tex]\frac{Diameter}{2}=\frac{4.6cm}{2}=2.3cm[/tex]
So,
Volume of sphere = [tex]\frac{4}{3}\times 3.14\times (2.3cm)^3[/tex]
Volume of sphere = [tex]50.94cm^3\approx 51.0 cm^3[/tex]
Water displaced = Volume of sphere = [tex]51.0 cm^3[/tex]
We know that:
[tex]1cm^3=1mL[/tex]
So,
Water displaced = 51.0 mL
Therefore, the correct option is (A) 51.0 mL
Answer:
A. 51.0 mL

Answer:
Both are nuclear reactions that produce energy,but the applications are not the sameExplanation:
Fission -is the spitting of a heavy,unstable nucleus into two lighter nuclei Fussion -is the process where two light nuclei combine together releasing vast amounts of energy.When a solid is placed in a container and heat is applied, a phase change occurs. Watch the video and identify which of the following statements are correct.
a) The temperature increases while all of a liquid is converted to a gas.
b) The average kinetic energy of the system changes while all of a solid is converted to a liquid.
c) Temperature remains constant while all of a solid is converted to a liquid.
d) When heat is applied to a solid, the molecular motion decreases as the temperature increases.
e) When a solid is converted to a liquid, heat is absorbed.
Answer:
Temperature remains constant while all of a solid is converted to a liquid.
When a solid is converted to a liquid, heat is absorbed.
Explanation:
During a phase change, the temperature of the system remains constant. Recall that latent heat is defined as heat that causes a change of state without a corresponding rise in temperature of the system.
When a solid is converted to a liquid, latent heat of fusion is involved hence the temperature of the system remains constant throughout the process.
Similarly, heat is absorbed as intermolecular forces are broken up and the would converts to liquid.
