Answer:
Knowing that the temperature at sea level (0 m) is 20 ° C, we will calculate the air temperature at. The altitude of 3500m.
According to the vertical thermal gradient, the air temperature decreases by 6 ° C at 1000m alt.
1000 m .... 14 ° C (20-6 = 14)
2000 m .... 8 ° C (14-6 = 8)
3000 m ... 2 ° C (8-6 = 2)
3500 m .... - 1 ° C (2-3 = -1
Explanation:
I would say B because of their population
<u>Answer</u>:
When Uranium-238 decays, it emits 8 Alpha particles and 6 beta particles before finally becoming the stable daughter product. The atomic number and mass number of the daughter product is 92 and 234 respectively.
<u>Explanation</u>:
In the process of decay of Uranium-238, it emits alpha particles, and the resultant product is Thorium-234, which turns into Protactinium-234, and this Protactinium-234 undergoes the beta decay to form the Uranium-234.
As per the question, a stable daughter product is created after the emission of alpha and beta particles, this implies that Uranium-234 is a stable product after the decay of Uranium-238. Therefore, the atomic number is 92 (number of protons) and the mass number is 234 (protons+neutrons) which is also the element of the naming.
Rwanda (4) was the site of ethnic tensions and a civil war between the Hutu and the Tutsi in the 1990s. In early to middle 1994, the Hutu ethnic majority murdered nearly 800 thousand people, mostly from the Tutsi minority group. The act of attempting to annihilate an ethnic minority by an ethnic majority is known as a genocide. In Rwanda, the genocide began in the capital city of Kigali and spread throughout the rest of the country with lightening speed. It was a brutal and violent period in Rwandan history.
