The half-life of uranium-235 is 700,000,000 years. 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.
To find the half-life of uranium-238, we need to find the difference between the half-life of uranium-238 and uranium-235.
The half-life of uranium-238 is an additional 4.463×10^11 years longer than the half-life of uranium-235.
Therefore, the half-life of uranium-238 is:
700,000,000 years + 4.463×10^11 years = 446,300,000,000 years
Therefore, the half-life of uranium-238 is 446,300,000,000 years.
To find the half-life of uranium-238, we need to add the additional time to the half-life of uranium-235.
Given:
Half-life of uranium-235 = 700,000,000 years
Additional time = 4.463×10^11 years
To find the half-life of uranium-238:
Half-life of uranium-238 = Half-life of uranium-235 + Additional time
Substituting the given values:
Half-life of uranium-238 = 700,000,000 years + 4.463×10^11 years
Now, we need to convert the additional time from scientific notation to decimal form. The scientific notation 4.463×10^11 can be written as 446,300,000,000.
Half-life of uranium-238 = 700,000,000 years + 446,300,000,000 years
Half-life of uranium-238 = 446,300,700,000 years
Therefore, the half-life of uranium-238 is 446,300,700,000 years in decimal form.
To find the half-life of uranium-238, we know that it is 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 need to add the additional time to the half-life of uranium-235:
Half-life of uranium-238 = Half-life of uranium-235 + Additional time
Since the additional time is given as 4.463×10^11 years, we can substitute this value into the equation:
Half-life of uranium-238 = 700,000,000 years + 4.463×10^11 years
To simplify the expression, we can convert the scientific notation to decimal form:
Half-life of uranium-238 = 700,000,000 years + 446,300,000,000 years
Now we can add the two values:
Half-life of uranium-238 = 446,300,700,000 years
Therefore, the half-life of uranium-238 is approximately 446,300,700,000 years in decimal form.
