How did using metal help ancient chinese people increase food production.

Answers

Answer 1
How did using metal help ancient Chinese people increase food production? It led to wet farming for rice. It led to planting crops in rows. It led to stronger plows for tilling.

How they grew food: Rice and millet were the two main crops grown in Ancient China. Rice paddy (field) flooded from river. Rice needs a lot of water, so the Chinese figured out how to flood the fields from rivers to make rice paddies (fields for growing rice).

How did the Chinese improve farming?: By the Tang dynasty (618–907), China had become a unified feudal agricultural society again. Improvements in farming machinery during this era included the moldboard plow and watermill. Later during the Yuan dynasty (1271–1368), cotton planting and weaving technology were extensively adopted and improved.

Which of the following is an example of the self-fulfilling prophecy?.

Self-fulfilling prophecy is a psychological theory where what is believed or expected or said to a person comes to pass even if the belief is not a fact.

An example of  self-fulfilling prophecy is telling a person that they are so poor in mathematics. This might not be true but because the person is told repeatedly, the person begins to believe it and would eventually become poor in mathematics.

Self-fulfilling prophecy can be negative or positive. It depends on the way it is used.

Would sound waves travel slower through air at the north pole or at the equator?.

Answers

yes they would travel slower at the north pole than the equator because the air is more dense and is harder to pass through

Yes, sound waves would travel slower at the North Pole than at the equator because the air is denser and is harder to pass through.

What are equators?

The Equator is the midline of the earth.  A vibration results in a sound. We refer to these motions as "sound waves." Sound waves require a specific medium to travel through. The three different types of media are solid, liquid, and gas.

Keep in mind that since a "solid medium" is denser than the other two, sound waves move through it more quickly. Because water is more densely packed with particles than gas is, sound waves travel faster in liquid than in gas (such as air).

Therefore, yes, because the air is heavier and more difficult to get through at the North Pole than it is at the Equator, sound waves would move more slowly there.
