The number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.
<h3>What is a resistor?</h3>
In an electronic circuit, a resistor is an electrical component that limits or regulates the flow of electrical current.
Given, the resistance is 20 ohms.
The potential difference is 30 volts
Time is 10 minute
By the formula of current
The charge flowing through the resistor is 1.5 C/s
1 electron charge is 1.6e+19
Now, the number of electrons passing through a 20 ohms resistor is
In 10 minutes
Thus, the number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.

The possible values for the missing number that make the given expression the square of a binomial is; 81
<h3>Binomial Expression</h3>
We are given the expression;
x² + 18x
- Now, if we consider the binomial; x ± b
Squaring that gives us;
x² ± 2ax + b²
Comparing this expression to the one we are given we can say that;
±2ax = 18x
±a = 18/2
a = ±9
Thus,we will have;
(x + 9)² as our expression which is;
x² + 18x + 81
Therefore, the missing number is 81.

The federal reserve notes are usually called flat notes because they have value due to government decree.
<h3>What are federal reserve notes?</h3>
The Federal Reserve usually controls the money supply by raising or lowering the discount rate, by raising or lowering the reserve requirement, by buying and selling government bonds and treasury bills.
Now, the federal reserve notes are usually called flat notes because they have value due to government decree.

Dan runs a busy desktop-publishing company. His company wants to increase its exposure, so it runs a new promotion each week. The tool Dan most likely chooses to publicize this promotion is a blog.
Using a blog is a great tool to communicate with your audiences and target groups. In a blog, you can also include all the promotions you want because you know that people that visit your blog are people who are interested in your company's products. So when they're there, they could notice the promotions, and read an article or getting more familiar with the company and their products.
