It depends on the length of the string and the speed its swinging at. If its short then it will reach the full swing in less of a time but if its a longer string then it would take a longer time to make a full swing.
Answer:
25g
Explanation:
Given parameters:
Half life of X = 5days
Mass of sample of radioactive elements = 100g
The half-life of a radioactive material is the time it takes for a sample to decay by half. At the half-life, an original sample would have yielded equal daughter to parent ratio.
At time (days) Mass of sample
0 100g
5 50g
10 25g
Every 5 days, the sample will split into half.
Therefore, 25g will remain after 10days.
