Answer:

Option: C. The Aztecs and others could not compete against advanced European technology.

Explanation:

In technological terms, Aztec and others were not well equipped when it came to war with Spanish soldiers and conquistadors. Aztec used tools like spears, clubs, bows, and darts, which were primitive compare to Spanish warfare technology. Spanish had steel weapons like lances, swords, cannons, and horses, which helped them defeat the Native Americans.

An ant has a mass of approximately 4 x 10-3 grams and an elephant has a mass of approximately 8 x 106 grams.
Ludmilka [50]

Answer: An ant has a mass of approximately 4×10âˆ′3 grams and an elephant has a mass of approximately 8 metric tons.

How many ants does it take to have the same mass as an elephant?

An ant is 10âˆ′1 cm long. If you put all these ants from your answer to part (a) in a line (front to back), how long would the line be? Find two cities in the United States that are a similar distance apart to illustrate this length.

Note: 1 kg = 1000 grams, 1 metric ton = 1000 kg, 1m = 100 cm, 1km = 1000 m

IM Commentary

In this problem students are comparing a very small quantity with a very large quantity using the metric system. The metric system is especially convenient when comparing measurements using scientific notations since different units within the system are related by powers of ten.

Solution

First we observe that the mass of the ant is in grams, where the mass of the elephant is in metric tons. We cannot compare the two masses as is, so we first convert them into the same units. We can do this with ratios, using the conversion chart above to convert metric tons into kilograms and then kilograms into grams.

(8 metric tons)(1000 kg1 metric ton)(1000 grams1 kg)=8,000,000 grams=8×106 grams

Notice that both metric tons and kg appear once on both the top and the bottom, enabling them to be canceled out, leaving only grams. Also note that we could have converted .003 grams into metric tons, and though this would have given an answer with a large number of decimal places, we would end up with the same final result.

Now that both quantities are in grams, we want to find how many ants, n, are required to have the same mass as the elephant. As each ant has a mass of 4×10âˆ′3 grams, we multiply 4×10âˆ′3 by n to get the total mass of the ants

total mass of n ants=4×10−3n

and then we set this equal to the mass of the elephant:

4×10−3n=8×106

We find that n=2×109 ants.

Thus, it takes approximately 2×109 ants to have the same mass as an elephant.

Each ant is 10âˆ′1 cm long, and we have 2×109 ants total. If we put all these ants in a line (front to back), we can find the length of the line by multiplying the length of one ant by how many ants we have:

2×109×10âˆ′1 cm=2×108 cm

As is, this answer is difficult to illustrate because it is such a large number. To find two objects that are this distance apart, we first want to convert centimeters into more useful units. We do this by using ratios from the above chart, converting centimeters to meters and meters to kilometers.

(2×108 cm)(1 m102 cm)(1 km103 m)=2×103 km=2000 km

This amount is much easier to visualize, and it turns out that 2000 km is approximately the driving distance from San Francisco, California to Denver, Colorado.An ant has a mass of approximately 4×10âˆ′3 grams and an elephant has a mass of approximately 8 metric tons.

How many ants does it take to have the same mass as an elephant?

An ant is 10âˆ′1 cm long. If you put all these ants from your answer to part (a) in a line (front to back), how long would the line be? Find two cities in the United States that are a similar distance apart to illustrate this length.

Discuss the relationship between politics and religion by examining the wars of religion. (european history)
uranmaximum [27]
Most of early history, these was no seperation of church and state, so they were one and the same.
This applies to both the English civil war ( if you can call any war civil) and the Dutch revolt. Both were to end Catholic domination of the Protasant subjects.
All wars are both religious and political. But end up anti-religious as they violate the very tenets of any religion they expound so it is only being about power.
Protasants revolted against the Catholics for freedom but then in-fighting over which Protasant religion is good.
The politics of any war are power and greed. Someone wants what someone else has and demands the right to take it and deny others taking it from them.
Many claim they are trying to protect the ' true' religion or claim for religious freedom and then show they are no better then the heritics they decry and deny others the same freedoms they want,
When all is said and done - all is just for power.
War has never settled any differences. It just pospones the reversal of power as will always happen. The French Revolution almost did by beheading the royals but as many escaped and Napolian brought new ones in. Nothing much changed.
The American revolution - which was the 1st non-religious war started the change for wars to not just be about religion.
