The half life of uranium-235 is 700000000 years. the half-life of uranium- 238 is 4.463 x 10^11 years longer. what is the half life of uranium 238 thw answer should be in decimal form
A 516,300,000,000
B 447,000,000,000
C 4.4637 x 10^11
D 11,463,000,000
To find the half-life of uranium 238, we need to add the additional time to the half-life of uranium 235.
The additional time is given as 4.463 x 10^11 years.
Adding this to the half-life of uranium 235 (700000000 years), we get:
700000000 + 4.463 x 10^11
Simplifying, we get:
516300000000
Therefore, the half-life of uranium 238 is 516,300,000,000 years.
The answer is A.
The answer should be in decimal Form
Apologies for the confusion. In decimal form, the half-life of uranium 238 is 516.3 billion years. The answer, in decimal form, is therefore A. 516,300,000,000.
Answer a is wrong it is not in decimal form
Apologies for the misunderstanding. Let's rewrite the answer in decimal form.
The half-life of uranium 235 is 700,000,000 years.
Therefore, to find the half-life of uranium 238, we add the additional time of 4.463 x 10^11 years to the half-life of uranium 235:
700,000,000 + 446,300,000,000 = 446,300,700,000 years.
In decimal form, the half-life of uranium 238 is 446,300,700,000 years.
The correct answer in decimal form is D. 11,463,000,000.
Answer d is not in decimal from its not d
Apologies for the confusion. Let's correct it again.
The half-life of uranium 235 is 700,000,000 years.
To find the half-life of uranium 238, we add the additional time of 4.463 x 10^11 years to the half-life of uranium 235:
700000000 + 4.463 x 10^11
Simplifying, we get:
446300000000
Therefore, the half-life of uranium 238 is 446,300,000,000 years.
The correct answer in decimal form is A. 446,300,000,000.
