the half-life on uranium-235 is 700,000,000 years. the half-life of uranium-238 is 4.463x10^11 years longer. what is the half-life of uranium-238? the answer should be in decimal form

Answer 1

To find the half-life of uranium-238, we need to add the additional time to the half-life of uranium-235.

Half-life of uranium-235 = 700,000,000 years

Additional time for uranium-238 = 4.463 x 10^11 years

The half-life of uranium-238 = 700,000,000 + 4.463 x 10^11

= 446,300,000,000 years

So, the half-life of uranium-238 is approximately 446,300,000,000 years in decimal form.
