Explanation:
When an atomic nucleus emits an alpha particle it decay into an atom with atomic number 2 less and mass number 4 less. Thus Thorium 230 decay as follows.
230 90Th -------> 226 88Th + 4 2 He
thorium is in the atomic number 90 thus it during alpha decay it reduces to atomic number 88 while its 230 mass number reduces to 226
Answer:
32 meters
Explanation:
You use the formula a^2 + b^2 = c^2.
Plug in the length and hypotenuse.
60^2 + b^2 = 68^2
Simplify and Solve:
3600 + b^2 = 4624
4624 - 3600 = b^2
1024 = b^2
Sqrt 1024 = 32
b = 32
It would be 1 or 2 because if the number is higher than 5 you need to round up , if its lower than 5 you need to round down.
