Answer:
To calculate the percentage of l-131 that has decayed up to the year 2021, we need to determine how many half-lives have passed from 1959 to 2021 and then calculate the remaining percentage.
The half-life of l-131 is 8.02 days.
First, calculate the number of half-lives that have passed from 1959 to 2021:
Number of years = 2021 - 1959 = 62 years
Since each year has approximately 365 days:
Number of days = 62 years * 365 days/year = 22,630 days
Now, calculate the number of half-lives:
Number of half-lives = Number of days / Half-life = 22,630 days / 8.02 days/half-life ≈ 2822 half-lives
Now, we know that each half-life reduces the remaining amount to half. So, to calculate the percentage remaining after 2822 half-lives:
Percentage remaining = (1/2)^2822 * 100 ≈ 0%
So, approximately 0% of the initial l-131 has decayed up to the year 2021.

Answers
Answer:
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
Explanation:
As we know that average velocity is defined as the ratio of change in position and the time interval of the object
It is given as
so we will have
= displacement
= time interval
the direction is this average velocity is always along the direction of the displacement
so correct answer will be
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
