Fossil evidence puts the existence of the Homo mauritanicus species at approximately 1.2 to 0.6 million years ago.
Answer:
See solution and explanation below
Explanation:
a) From;
N/No = (1/2)^t/t1/2
1/8 = (1/2)^t/1.25 * 10^9
(1/2)^3 = (1/2)^t/1.25 * 10^9
3 = t/1.25 * 10^9
t = 3 * 1.25 * 10^9
t = 3.75 * 10^9 years
b)
N/No = (1/2)^40,110/5,730
N/No = (1/2)^7
N/No = 1/128
percentage remaining after 40,110 years = 1/128 * 100 = 0.78%
c) N/200 * 10^-9 = (1/2)^4.26 * 10^9/0.710 * 10^9
N/200 * 10^-9 = (1/2)^6
N/200 * 10^-9 = 1/64
64 N = 200 * 10^-9
N= 3.125 * 10^-9 g
d) Radiocarbon dating can not be used to determine the age of the solar system since the solar system is as old as the universe and was formed billions of years ago. Radiocarbon dating can only be accurately used to obtain the age of objects of plant or animal origin between 1000 - 10000 years old.
Answer: from 64°F to 94°F and is rarely below 59°F or above 100°F.
Explanation:
Answer:
O to reduce its dependence on its oil industry for revenue
Explanation:
Oman used to be one of the poorest countries in the Middle East, until Oil was discovered there (Same story with UAE, and Qatar). So when they run out of Oil, they will be completly reliant on Manufacturing, Exporting, and Tourism.
