The half-life of uranium-235 is 700,000,000 years. The half-life of uranium-238 is 4.463×1011 years longer. What is the half-life of uranium-238? The answer should be in decimal form.(1 point)
Responses
A
447,000,000,000
B
516,300,000,000
C
11,463,000,000
D
4.4637×1011
To find the half-life of uranium-238, we add the given 4.463×10^11 years to the half-life of uranium-235, which is 700,000,000 years.
So, the half-life of uranium-238 is 700,000,000 + 4.463×10^11 = 516,300,000,000 years.
Therefore, the correct answer is B) 516,300,000,000.
