2 solutions because you have 2 different equations
This is the same as 3/18 x 21/7, which you can simplify to 1/6 x 3, which is 3/6 also a half. So the answer is 1/2
Answer: the mass of a neutron is approximately 2,000 times the mass of an electron
Step-by-step explanation:
- the easiest way to solve this (in my opinion) is to simply divide the mass of a neutron by the mass of an electron
- ![2 x10^{-24} / (9 x10^{-28} )](https://tex.z-dn.net/?f=2%20x10%5E%7B-24%7D%20%2F%20%289%20x10%5E%7B-28%7D%20%29)
= ![(2/9) x10^{-24--28}](https://tex.z-dn.net/?f=%282%2F9%29%20x10%5E%7B-24--28%7D)
= ![(2/9)x10^{-24+28}](https://tex.z-dn.net/?f=%282%2F9%29x10%5E%7B-24%2B28%7D)
≈ ![0.2222x10^{28-24}](https://tex.z-dn.net/?f=0.2222x10%5E%7B28-24%7D)
≈ ![0.2222x10^{4}](https://tex.z-dn.net/?f=0.2222x10%5E%7B4%7D)
≈ which is approximately 2222
- so 2222 is approximately 2000 times
- therefore, the mass of a neutron is approximately 2,000 times the mass of an electron
hope this helps :)
Find the side length:
Side = 68/4 = 17
Now use Pythagorean theorem:
Diagonal = sqrt(17^2 + 17^2)
Diagonal = sqrt(289 + 289)
Diagonal = sqrt(578)
Diagonal = 24 feet
The answer is B. 24 feet
