Explanation:

In Asian cultures, words that could be translated to yes or no depend on the context and grammar of the question. Japanese people may say ´Yes´ to something they don´t agree on, as in Japanese  ´yes´ usually means ´Yes, I heard you´ and not ´Yes, I agree´.

Similarly, in Chinese, saying ´Yes´ might be only a way to avoid disappointing the other person, as it could mean that they heard the other person or that they are paying atention, and not necesseraly that they agree.

a. formula: f=ma or f/m=a

10,000n/1,267kg≈7.9m/

b. formula: a= and s=d/t

speed= 394.6/15

s=26.3m/s

a=

a=1.75m/

c. 7.9-1.75=difference of 6.15m/

d. the force that most likely caused this difference is friction forces

for many centuries there were important factors which the economies of the muslim empires developed increasingly. they applied economic procedures in production, investment, finance, taxation and property. they used to tax certain goods (for example: harvest), they charged interest on money lent, they signed contracts with merchants; they relied on a common currency, and they used checks as well as promissory notes. with the money collected by means of taxation, the government provided the needy with an income. in addition, trading networks covered huge distances, so far regions started to have contact and exchange goods. this trade network covered areas of asia, africa and europe.
