determine the force of gravitational attraction between a 78kg boy sitting 2 meters away from a 65kg girl.

Answers

Answer 1

Answer:

F = 8.45 * 10^-8 N

Explanation:

The gravitational force is calculated using

F = GMm/r²

Where

G represent gravitational constant = 6.67 * 10^(-11)

M = Mass of the boy = 78kg

m = Mass of the girl = 65kg

r = Distance between them = 2m

Substitute these values in the formula, we have:

F = (6.67 * 10^(-11) * 78 * 65)/2²

F = (6.67 * 78 * 65 * 10^(-11))/4

F = (33816.9 * 10^(-11))/(4)

[Divide by the denominator]

F = 8454.225 *10^(-11)

[Expand]

F = 8.454225 * 10³ * 10^(-11)

F = 8.454225 * 10^(3-11)

F = 8.454225 * 10^-8

[Approximate]

F = 8.45 * 10^-8 N

Hence, the force of attraction between them is 8.45 * 10^-8 N

Why do you think Hammurabi made so many laws?

Answers

Answer:

To maintain the stability in his empire.

Explanation:

The codex of Hammurabi was notorious for giving harsh punishment for criminals who violated the laws.  (One small example, if you're caught stealing in his reign, your arms would be cut off)

I think , he imposed these laws and harsh punishment to maintain the safety and stability of his empire.

If criminal behaviors were left unpunished, the other citizens wouldn't feel safe to do productive activities such as farming, learning, or even walk at night. They would live in constant fear that someone will just come into their house and steal everything that they've worked hard for.

Imposing harsh punishments will massively discouraged the criminals. As a result, the citizens could focus all of their energy on productive things.

C.
the Falls of Ohio

Answers

Answer:

Option: C. the Falls of Ohio

The falls of Ohio was an obstacle for steamboats travelling down the Ohio River in the 19th century because of its geographic features which included a series of rocky rapids.

Smaller boats were able to navigate the falls in high water, but larger steamboats always ran the risk of damage.

Do you think Han officials would be pleased about trading bolts of silk for 200 horses? Explain

Answers

Answer:

Yes, I believe they would.

Explanation:

Bolts of Silk was considered a luxurious goods during that time period. It mostly sold toward nobles with a really high price.

That's being said, the Han officials main interest during their reign was not economic growth. They wanted to acquire the territories of other empires that were  located in Central Asia. In order to do this, they initiated several war campaigns throughout that region.

For war campaigns, horses are far more valuable than silk. They can be used as cavalries or methods of transportation to deliver supplies for their soldiers.  This was the reason why they would probably be content with that exchange.

You don’t get it, do you. Neither anthropology, nor sociology, nor political science, have “natures” or “goals” - only people do - as anthropods, as social individuals, as polities: and their natures thus are very varied, and the goals are multifarious, and the studies of these variations are what constitue anthropology, sociology and political science. And because of the great variations involved, you CANNOT start off by making the simplifyng assumption - “Well, all people are basically the same” - hence mega loads of b/s.
