Why are sodium (Na) and potassium (K) in the same group on the periodic table? (1 pc
O They have similar reactivity.
O They are both colorless.
They have similar atomic weights.
They are both hard and brittle.
Answer:
they have similar reactivity
Explanation:
they are both in the same group so that means they have the same amount of valence electrons they shoudl have different amount of electron shells sodium would be more reactive by a little bit.
Sodium (Na) and Potassium (K) are found in the same group on the periodic table due to the fact that they have similar reactivity. Thus, option 'similar reactivity' is the correct option.
Why are sodium (Na) and potassium (K) in the same group on the periodic table?Group 1 of the periodic table contains the highly reactive chemical elements sodium and potassium. As a result of having their valence electron in the outermost s orbital, they are s-block elements.
Because they may be combined to create a wide range of chemical compounds, sodium and potassium are both extremely valuable chemical elements. Since sodium and potassium are two separate chemical elements, there are variances between them.
The size of sodium atoms vs potassium atoms is the primary distinction between the two elements. As a result of being in the same group on the periodic table, they have many things in common.

Explanation:
The collection of data through various means relates to the concept of survey. Surveys can be done to collect data using various different methods of data collection.
Which is typically easier method to collect data?The data collection from a large number of scattered public would be a complicated and lengthy process. This data will be comparatively less complete and less reliable.
The data collected from the original source which has the primary raw data is more reliable and genuine and it is easy to collect too.

Which is a true statement about
Eastern Europe?
A. Eastern European government and economics
are very unstable.
B. Eastern Europe includes the nations of Italy
and Libya.
C. Eastern Europe has the largest population in
the world.
Answer:
Answer A (if I need to choose from those three options). However it depends on the country.
Explanation:
B - Libya is not in Eastern Europe (is in North Africa)
C - the largest population in the world is in China or being more general Asia.
Eastern European government and economics are very unstable is a true statement about Eastern Europe. Thus option A is correct.
What is Eastern Europe?The portion of the European continent is known as Eastern Europe. It has a broad range of diplomatic, territorial, ethnographic, cultural, and social meanings because it is a term that is generally imprecise.
Eastern Europe's political, religious, and industrial capitals were decimated by the Mongols. They wouldn't fully recover for generations; by that time, the Western side had advanced. In a time of great uncertainty, a concoction of dangers poses a threat that derail growth.
A more challenging climate than the nation has ever faced is created by geopolitical rivalry and unrest in adjacent countries, significant economic and social inequality, and increasing global warming. Therefore, option A is the correct option.

using kenya as an example,,,,,,,evaluate the role of primate cities in national development
Explanation:
A primary purpose of this report is to stimulate within the
U.S. Agency for International Development (A.I.D.) a discussion
on urbanization in developing countries and the importance
urbanization can play in shaping national economic growth and
development. Directed to project and program designers and
Mission strategists, the report contends that there has been a
rural-urban "divide" in the Agency and in developing country
governments. The divide is viewed in the context of a growing
antiurban bias and in the perception that urbanization is somehow
"bad. n Although urbanization is not occurring along the same
lines in the developing countries as it has in Western countries,
it can, and in some cases does, contribute effectively to overall
national economic growth and development.
This report argues that urbanization in developing countries
falls along a continuum between extreme types. Type 1 occurs
when overall national economic growth and development are pre-
sent. Type 2 occurs when there is inadequate overall growth,
even underdevelopment.
In a review of regional trends, much of Sub-Saharan African
urbanization falls under Type 2, namely, rapid urbanization and
urban growth with limited national development. The Near East is
skewed toward increased concentration of urban peoples in the
largest cities, but generally in the context of moderate devel-
opment across the region. Asia shows a mixture of Types 1 and 2,
a case of "mixed" urbanization. There, Type 1 applies mainly to
the middle-income, newly industrializing countries, while Type 2
applies mostly to low-income countries experiencing low
agricultural production, low employment and income, and high
rates of rural migration to megacities. For Latin America, a
mixture of Types 1 and 2 also occurs, mainly in the form of
"overurbanization" and slowed development.
Factors of national importance in urbanization include
socioeconomic conditions and policies that have a direct impact
on a country’s human settlements; for example, national policy
that directly affects income and employment has indirect effects
on those settlements. Another major factor that affects urbani-
zation is migration by rural households to urban areas in
response to economic incentives. In developing countries,
households respond to such incentives in choosing places to work.
Equally important is the character of rural-urban linkages. In
places where urbanization is of Type 1, rural-urban linkages
actively contribute to a dynamic marketing system; but for Type
2, such linkages do not create opportunities for

LEDCs have become attractive sites for manufacturing and tertiary services such as help lines because lower labor costs and access to information and technology
True or False
It is true that LEDCs have become attractive sites for manufacturing and tertiary services such as helplines because of lower labor costs and access to information and technology.
This is because LEDCs, which is an acronym for Less Economically Developed Countries, have various policies and economic factors that enhance companies to set up their business there.
Cheaper labor, tax evasion, and less pollution have been some of the many reasons why manufacturing and tertiary services get set up in these areas.
This is evident in that approximately 300,000 United States jobs are lost to foreign outsourcing every year.
Also, over 560,000 Californian jobs have been outsourced to China since the turn of the millineum.

Some geologists are finding evidence that suggests that this one-mile deep canyon may have been cut within the last 4 million years. Assuming a uniform rate of erosion and without considering canyon widening due to slope retreat, calculate how much (in millimeters per year) the Colorado River would have to downcut per year to form this mile-deep canyon in 4 million years. Show your work and clearly indicate what each quantity represents.
The number that Colorado River would have to downcut per year to form the mile-deep canyon in 4 million years is 0.40 millimeter per year.
Depth of canyon = 1 mile
Time taken = 4 million years
Based on the above information, the rate will be:
= Depth / Time taken
= 1 mile / 4 million years
= 0.25 mile / million year
Note that 1 mile = 1609344 millimeter
Therefore, the rate will be:
= (0.25 × 1609344) / 1000000 years
= 0.40 millimeter / years
In conclusion, the rate is 0.40 millimeter per year.

MOVEMENT How would you describe the difference between changes in the geographic center and changes in the population center?
Answer:
The mean center of population is the place where an imaginary, flat, weightless, and rigid map of the United States would balance perfectly if all residents were of equal weight. Historically, the movement of the center of population has reflected the expansion of the country, the settling of the frontier, waves of immigration and migration west and south. Since 1790, the center of population has moved steadily westward, angling to the southwest in recent decades.
