Answer:
Sudans many years of civil war have resulted from conflicts between "Muslim Arabs, and Christian and animist Africans.
"
Explanation:
Religion is the essential effect in Sudan’s civil war. The North, with most of Sudan's land and inhabitants, is Muslim and Arabic-speaking, and their religion and language are both important for their individuality. On the other hand, the South´s individuality is indigenously African, with Christian and Western influences. Sudan's first civil war was fought between the Arab-led Khartoum government in the north and rebels in the largely Christian and animist south. Southern rebels were fighting for regional autonomy and representation in the government. A peace agreement was signed in 1972 that granted semi-autonomy to the south.
A radioactive element with a half-life of 1,000 years, and starting mass of 20 grams, will need 2,000 years to decrease to 5 grams.
Explanation:
The radioactive elements all have a specific half-life. Each element's half-life is well known, and they are used by scientists of numerous fields as they are excellent for determining the age of a particular item, be it or organic or non-organic nature. In this case, we have a radioactive element with a half-life of 1,000 years, and starting mass of 20 grams.
The half-life basically means that half of the mass of an element is lost during a particular period of time. For the element in question we need to find out how much time will be needed for it to decrease to 5 grams. In order to get to the result, we just need to add 1,000 years on every decrease of half of the mass:
20/2 = 10
10/2 = 5
So in 1,000 years, the element in question will decrease to 10 grams, and in further 1,000 years (2,000 cumulatively) it will decrease to 5 grams.
