Answer:the will have the same acceleration
Explanation:according to fállelos theory they land at the same time
<span>F=ma = 3000x2m/sec^2 =6000 newtons. </span>
It could be radiation because radiation means <span>the emission of energy as electromagnetic wave, but potential fits it best</span>
Answer: 0.333 h
Explanation:
This problem can be solved using the <u>Radioactive Half Life Formula</u>:
(1)
Where:
is the final amount of the material
is the initial amount of the material
is the time elapsed
is the half life of the material (the quantity we are asked to find)
Knowing this, let's substitute the values and find
from (1):
(2)
(3)
Applying natural logarithm in both sides:
(4)
(5)
Clearing
:
(6)
Finally:
This is the half-life of the Bismuth-218 isotope
