The half-life of uranium-235 is 700000000years The half-life of uranium-238 is 4.463 * 10 ^ 11 years longer. What is the half-life of uranium-238? The answer should be in decimal form. (1 point)

Question

O 447,000,000,000

O 516,300,000,000

11,463,000,000

4.4637 * 10 ^ 11

Answer 1

To find the half-life of uranium-238, we need to subtract the half-life of uranium-235 from the given value of 4.463 * 10^11 years.

4.463 * 10^11 - 7.000 * 10^8 = 4.4563 * 10^11 years

Therefore, the half-life of uranium-238 is 4.4563 * 10^11 years, which in decimal form is 445,630,000,000 years.

So, the correct answer is 445,630,000,000 (option O 447,000,000,000).

Answer 2

Huh

Answer 3

I apologize for the confusion in my previous response. Let's correct it.

To find the half-life of uranium-238, we need to subtract the half-life of uranium-235 from the given value of 4.463 * 10^11 years.

4.463 * 10^11 - 7.000 * 10^8 = 4.4563 * 10^11 years

Therefore, the half-life of uranium-238 is 4.4563 * 10^11 years, which in decimal form is 445,630,000,000 years.

So, the correct answer is 445,630,000,000 (option O 447,000,000,000).
