what is periodic table​

Answers

Answer 1

Explanation:

The periodic table is a chart or table of the elements arranged into columns and rows according to their physical and chemical properties.

Hope it will help :)

Answer 2

Answer:

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.

Explanation:

The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right.

The columns, called groups, contain elements with similar chemical behaviours.

Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases.

Why might some civilizations not have been part of the Neolithic Revolution?
A. None of the animals around them could be domesticated.
B. They could not see the smoke signals that carried news of the revolution.
C. They chose to be passive observers. D. They did not need agriculture or food surpluses.​

Answers

I’d say C.

A doesn’t make sense, they definitely could’ve domesticated animals in that time.

B doesn’t make sense either, they could’ve easily seen smoke signals, the sky wasn’t filled with them often.

C is just a weird answer. I doubt they were “passive observers” but probably the best answer to the question.

D doesn’t add up because they definitely needed agriculture/food surpluses. They were always hunting, they obviously ran out of food rather quickly.


So C is the answer.

Some civilizations not have been part of the Neolithic Revolution because None of the animals around them could be domesticated.

What is mean by civilization?

The word "civilization" is related to the Latin word "civitas," or "city," which is why it sometimes refers to urban state-level societies, excluding nomadic people who do not have a permanent home and those who reside in settlements that are not considered urban or do not have a state-level organisation. It is sometimes used to compare what many people view as less advanced nations with human societies "with a high level of cultural and technological development. Early civilizations emerged in various parts of the world as a result of the emergence of urban communities.

What was the Neolithic Revolution?

In human history, the Neolithic Revolution, often known as the Agricultural Revolution, signalled the shift from small, nomadic bands of hunters and gatherers to larger agricultural settlements and early civilization. crucial change that led to the development of agriculture, transforming Homo sapiens from dispersed bands of hunters and gatherers to farming communities, and from there to highly advanced societies with enormous temples and towers and monarchs and priests who oversaw their subjects' labour.

Characteristic of Neolithic Revaluation

Domesticated Animal

agrarian based society

Depended on the species which are locally locally available

therefore it can be said that who didn't have animal to domesticated around them, not able to been a part of Neolithic Revolution

hence option A is correct.

Lowlands are more likely to provide transportation for goods because they
O have more rainfall.
O have a tropical climate.
O are located by the ocean.
are located near mountains.

Answers

The answer would be near the ocean. All the rest don’t make sense. Mountains would be hard to travel across, rain would slow car travel/truck shipments and tropical climates would make it hard to travel through considering the trees and obstacles along the way. The ocean however, is usually very smooth and boats can travel across it with little to no issues.

Lowlands are more likely to provide transportation for goods because they are located by the ocean. Thus, the correct answer is option C.

What are lowlands?

Lowlands are regions with terrain that is at, close to, or below sea level and that typically lack mountains and significant hills. Lowlands, also known as Scottish Lowlands, is the name given to the cultural and historical region of Scotland.

As, Lowlands are located near the ocean, they provide good transportation for goods. Mountains would be hard to travel across as rain would slow car travel or truck shipments and tropical climates would make it hard to travel through considering the trees and obstacles along the way. The ocean however, is usually very smooth and boats can travel across it with little or no issues.

Therefore, nearness to the ocean provide the lowlands with transportation facility for goods.

O
rotation.
O
distortion.​

Answers

Answer:

D. Distortion.

Explanation:

In Geography, topography can be defined as the shape and structure of the Earth surface. Thus, a flat map is used to graphically describe this features.

Generally, elevations are represented on maps by lines of contour, which typically connect points having the same elevation. Also, elevations are shown on a physical map by using bands of color to connect points. In Geography, elevations are represented or measured in feets or meters.

Contours can be defined imaginary lines used for connecting locations that are having similar elevations on the Earth's surface. These contour lines are typically used for modeling the three-dimensional shape of the Earth surface in a map.

Hence, the changes in shape, size, and position of features that occur when representing the Earth on a flat map take place because of distortion.

Which evidence best supports the claim that plate tectonics causes earthquakes?

Question 7 options:

a.The distribution of rocks is determined by the history of plate motions


b. A transform boundary is created when two plates slide past one another


c. Continents, if put together, fit together perfectly to form a single super continent


d. Fossils on the eastern coast of South America are similar to those found on the western coast of Africa

Answers

Answer:

B; A transform boundary is created when two plates slide past one another.

Explanation:

I had this for a test question, picked B and got it right.

The statement that supports the claim that plate tectonics causes earthquakes is - "A transform boundary is created when two plates slide past one another". Thus, option (b) is correct.

What is earthquakes?

This movement causes earthquakes, which have a negative impact on the earth's crust ecosystem. As a consequence of these plate tectonic motions, volcanoes erupt, helping in the construction of new hills, and mountain ranges influence the climate.

Tectonic plates move relatively slowly relative to one other, often a few millimeters per year, yet this creates massive deformation near plate borders, resulting in earthquakes. There is no subduction, therefore the plates push apart.

Therefore, it can be concluded that option (b) is correct.

A child pushes a toy car down a hill. after 5 seconds, the car has kinetic energy of 115 J and a gravitational potential energy of 30 J. What is the car’s mechanical energy at that time.

Answers

Answer:

Mechanical energy = 145 Joules

Explanation:

Given the following data;

Kinetic energy = 115J

Gravitational Potential energy = 30J

To find the mechanical energy;

Mechanical energy = kinetic energy + gravitational potential energy

Substituting into the equation, we have

Mechanical energy = 115 + 30

Mechanical energy = 145 Joules.

Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
