The mass of an electron is approximately 9 × 10-28 grams, while the mass of a neutron is approximately 2 × 10-24 grams. Which of
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 :)

How many tons are equal to 36,000 pounds?
patriot [66]

Hello There! I'll be glad to help you! :0

Question:

How many tons are equal to 36,000 pounds?

Answer:

<h2><u><em>18 tons </em></u></h2>

Step-by-step explanation:

<em>To convert a pound measurement to a ton measurement, divide the weight by the conversion ratio.</em>

<em />

<em>Since one ton is equal to 2,000 pounds, you can use this simple formula to convert:</em>

<em />

<em>tons = pounds ÷ 2,000</em>

<em>The weight in tons is equal to the pounds divided by 2,000.</em>

<em />

<em>And you could multiply 2,000 by 18 and get the answer 36,000</em>

<em />

<em />

Hope This Helps you!

Have an Amazing day!

-5a-9+a=15 Explain please
IgorC [24]

Answer:

a = -6

Step-by-step explanation:

-5a-9+a=15

Combine like terms

-5a+a  -9 = 15

-4a  -9 = 15

Add 9 to each side

-4a -9+9 = 15+9

-4a = 24

Divide by -4

-4a/-4 = 24/-4

a = -6

DochEvi [55]

Answer:

Step-by-step explanation:

Here we want to present growth as a function of time; the growth depends upon the number of days that go by.  So, growth(y) is the dependent variable and time (in days, x) is the independent variable.
