Mark me brainlyiest and the answer is b I know becuase I took the test
1 electron has a mass of 9.1 X 10-31 kg. How many electrons n does it take to make 1 kg?
(1 e)/(9.1 X 10-31 kg) = n/(1 kg)
So, n = 1.10 X 1030 electrons
Each electron has a charge of 1.6 X 10-19 C, where C stands for Coulombs. So, the n electrons have a charge of q = ne = (1.10 X 1030 electrons) X (1.6 X 10-19 C/electron) = 1.76 X 1011 C.
<em><u>Hi there! :)</u></em>
<em><u>Answer:</u></em>
<em><u>x>24</u></em>
<em><u>*The answer must have a positive sign and greater than symbol sign.*</u></em>
<em><u>Step-by-step explanation:</u></em>
First, you switch sides.

Then, you subtract by 18 from both sides of an equation.

Finally, you subtract by the numbers from left to right.

<u><em>Final answer is x>24</em></u>
I hope this helps you!
Have a nice day! :)

Each number in the right column is 3 more than the value in the corresponding left column.
it's a right triangle so you use Pythagoras' theorem.
√28²-14²=
√784 - 196 =
√588
24.24 units (rounded 24.25)
your answer is 24.25 units
