السلام عليكم

algeria يقصد يالوفرة النظائرية النسبة المئوية لكل نظير و عادة يعطيلك نظيرين و يقلك ما هي الوفرة النظائرية لهذه النظائر و نحلوها بجملة معادلتين:
نعتبر x نسبة النظير الاول و y نسبة النظير الثاني حيث:

X+Y=1
xA̕+yA̕̕= A
A̕ هي العدد الكتلي للنظير الاول
A̕̕ هي العدد الكتلي للنظير الثاني
A هو العدد الكتلي للعنصر المعطى معناه لي عندو نظائر
نحلو جملة معادلتين و نلقاو المجهولين ثم نضربوهم في 100 نلقاو النسبة

first term english exam
--------------------------------------------------------------------------------

ENGLISH BAC PAPER (elaborated by Mr. Zaitri)
READ THE TEXT CAREFULLY THEN DO THE ACTIVITIES
As the Greek historian Herodotus once said ‘Egypt of the gift of the Nile’, the Nile River was the ancient Egyptians’ best friend even it did flood every year. In the fall, the great river would overflow its banks. At first the Egyptians lost their crops their houses and in some cases their lives. However, the Egyptian people noticed after a time that the floods came about the same time every year, in June. Therefore, they planned: they would make sure nothing important was on the banks of the river when it was time for the flood
Then after the water level went back down, they would quickly plant new crops. The floods brought good fresh soil up onto the land .This soil was ideal for planting grains.
The river also gave them the chance to fish. The Egyptians would build boats out of the wood and sail up and down the river. They would use spears and nets to catch fish as well as birds that flew close to the surface of the water.
The Nile also provided protection from attack. People wanting to invade Egypt would have first to cross the river, which was very wide in places. The Egyptians could stand on their own side of the river and throw spears at their r attackers. Any attacker who did cross the river was likely to be tired from making the crossing.
Another important way that the Nile helped the ancient Egyptians was in trade. Goods went to and from the Egypt down an up the Nile, which had its mouth at the Mediterranean sea . [PERSONAL REFERENCE]
