aalyn [17]

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} )

=  (2/9) x10^{-24--28}

=  (2/9)x10^{-24+28}

≈  0.2222x10^{28-24}

≈ 0.2222x10^{4}

≈ 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 prime factorization of 2001
marusya05 [52]
Rime factorization of 2001: 

By prime factorization of 2001 we follow 5 simple steps: 
1. We write number 2001 above a 2-column table 
2. We divide 2001 by the smallest possible prime factor 
3. We write down on the left side of the table the prime factor and next number to factorize on the ride side
4. We continue to factor in this fashion (we deal with odd numbers by trying small prime factors)
5. We continue until we reach 1 on the ride side of the table
