how did the concept of mercantilism influence the spread of new foods, plants, and animals around the world

Nina [5.8K]

Answer: Countries attempted to sell more than they bought. As a consequence, new foods, plants, and animals appeared on different markets all around the world.

Explanation:

Mercantilism is a country's policy to export more than it imports so as to bring prosperity and increase stores of gold and metals.

Mercantilism was very popular in Europe in the 16th century. Back then, wealth of a country largely depended on the amount of gold, silver and metals that it possessed. Countries attempted to establish a favorable balance of trade, which means that more goods are exported than imported. This resulted in a massive exchange of goods. For example, England forced their colonies to produce raw goods which were then shipped to Europe.

What was the most important preparation Ezra made for the journey to Jerusalem (Ezra 7:10)?

emmainna [20.7K]

Answer:

Some of the children of Israel, the priests, the Levites, the singers, the gatekeepers, and the Nethinim came up to Jerusalem in the seventh year of King Artaxerxes. And Ezra came to Jerusalem in the fifth month, which was in the seventh year of the king. On the first day of the first month he began his journey from Babylon, and on the first day of the fifth month he came to Jerusalem, according to the good hand of his God upon him. For Ezra had prepared his heart to seek the Law of the LORD, and to do it, and to teach statutes and ordinances in Israel.

Answer:

10.

So from 3:16; 16/3=5.33 (recurring) then to solve for the mass of zinc you divide 320 by 5.33 (recurring) to give you 60g which is the mass of the zinc

a. The equation is y = 19 x

b. The height of 13 DVD cases is 247 mm

Explanation:

12.

- A proportional relationship is about two quantities vary directly with

each other

- Ex: If y proportion to x, then y is varies directly with x That means y ∝ x ⇒ y = k x, where k is the constant of variation

- The height of a stack of DVD case is proportional to the number of case in the stack

- That means the height of DVD cases varies with the number of cases

- The height of 6 DVD case is 114 mm

a. ∵ The number of cases = x

∵ The height of the cases = y

∴ y ∝ x

∴ y = k x

- To find k lets use the first information above

∵ y = 114 mm when x = 6

- Substitute these values in the equation above to find k

∵ 114 = 6 k

- Divide both sides by 6

∴ k = 19

- Substitute the value of k in the equation above

∴ y = 19 x

* The equation is y = 19 x

-We need to find the height of 13 DVD cases

∵ y = 19 x

∵ x = 13

- Substitute the value of x in the equation

∴ y = 19 × 13

∴ y = 247 mm

* The height of 13 DVD cases is 247 mm

An object experiences a force of 24.5 N for a time period of 4.5 s . What is the impulse on the object ?

Bess [88]

Answer:

As mentioned in the previous part of this lesson, momentum is a commonly used term in sports. When a sports announcer says that a team has the momentum they mean that the team is really on the move and is going to be hard to stop. The term momentum is a physics concept. Any object with momentum is going to be hard to stop. To stop such an object, it is necessary to apply a force against its motion for a given period of time. The more momentum that an object has, the harder that it is to stop. Thus, it would require a greater amount of force or a longer amount of time or both to bring such an object to a halt. As the force acts upon the object for a given amount of time, the object's velocity is changed; and hence, the object's momentum is changed.

The concepts in the above paragraph should not seem like abstract information to you. You have observed this a number of times if you have watched the sport of football. In football, the defensive players apply a force for a given amount of time to stop the momentum of the offensive player who has the ball. You have also experienced this a multitude of times while driving. As you bring your car to a halt when approaching a stop sign or stoplight, the brakes serve to apply a force to the car for a given amount of time to change the car's momentum. An object with momentum can be stopped if a force is applied against it for a given amount of time.

A force acting for a given amount of time will change an object's momentum. Put another way, an unbalanced force always accelerates an object - either speeding it up or slowing it down. If the force acts opposite the object's motion, it slows the object down. If a force acts in the same direction as the object's motion, then the force speeds the object up. Either way, a force will change the velocity of an object. And if the velocity of the object is changed, then the momentum of the object is changed.
