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)
O 447,000,000,000
O 516,300,000,000
11,463,000,000
4.4637 * 10 ^ 11
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).
Huh
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).
To find the half-life of uranium-238, we need to add the given longer half-life to the half-life of uranium-235.
The half-life of uranium-238 is given as 4.463 * 10^11 years longer than the half-life of uranium-235, which is 700,000,000 years.
To calculate the half-life of uranium-238, we add the two values together:
700,000,000 + 4.463 * 10^11 = 516,300,000,000
Therefore, the half-life of uranium-238 is 516,300,000,000 in decimal form.
The correct answer is "516,300,000,000" (option B).
To find the half-life of uranium-238, we need to start with the given half-life of uranium-235 and find the difference in half-life between the two isotopes.
Given that the half-life of uranium-235 is 700,000,000 years, we subtract this value from the half-life of uranium-238, which is 4.463 * 10^11 years.
4.463 * 10^11 years - 700,000,000 years = 4.4623 * 10^11 years
Therefore, the half-life of uranium-238 is approximately 4.4623 * 10^11 years.
