The grand canal was built to make easier the transportation of grains to the power center of north china.

<h3>How was the Grand Canal built?</h3>

The canal was built in order to connect the Yellow River in the north with the Yangtze River in the south. This canal is built for making easier the transportion of grain from the south to the centers of north China. The total length of the Grand Canal is 1,776 km.

So we can conclude that the grand canal was built to make easier the transportation of grains to the power center of north china.

I AM GIVING 95POINTS HELP PLEASE!!
Firlakuza [10]

25,000 Feet = 7620m


PE = mgh where m is mass, g is gravity accel: 9.8 n h is height


= 90 x 9.8 x 7620


= 6720840J


= 6.72MJ


F = ma where m is mass, a is accel = gravity = 9.8


= 90 x 9.8


= 882N


Accel = gravity = 9.8m/s^2


KE = 1/2mv^2 where m is mass n v is vel


if no wind resistance, PE leaving airplane = KE at net


6720840 = 1/2 x 90 x v^2


v^2 = 149352


v = 386.5m/s


150MPH=67m/s


@150MPH, his speed is not changing so accel=0


accel=0, force=0 by newton's second law


force=0 when wind resistance = gravity = 9.8m/s^2


by conservation of energy, Luke's KE = PE = mgh = 6720840J


he was unhurt cuz' his momentum was absorbed by the net

الاضطراب العصبي يحدث بسبب ؟<br><br>​
tekilochka [14]

Explanation:

ا: قد يكون وراء هذه الظاهرة ميول وراثية، والتي تتسبب في صدور ردود فعل غير منتظمة في أماكن مختلفة معينة في الدماغ. تكون ردود الفعل هذه مسؤولة عن ظهور العلامات التي تميز العلامات المرافقة التي تظهر عند المرور في ظروف القلق.

ب: ان الفرضية السائدة والأساسية هنا، تقضي بأن العُصاب يظهر كردة فعلِ لفشل المنظومة النفسية الداخلية، في التأقلم مع القلق النابع من معاناة نفسية كبيرة. أو قد تنجم عن فشل المنظومة النفسية الداخلية في التأقلم مع الظروف الرضحية (التراجيدية) الخارجية والمحيطة.

ج:قد تظهر اضطرابات العُصابية من مزج بين تأثير التجارب الرضحية عند الطفولة، مع أسلوب الحياة المعاصر، والذي يتميز بوجود الإجهاد النفسي وبضعف الثقة بالمقومات الشخصية، الاجتماعية والاقتصادية
