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.

Median is the middle data in the list of the given numbers. In the given data set the median gets decreased by the presence of the outlier. Thus, option C is correct.
<h3>What is an outlier?</h3>An outlier is a data that varies significantly from the other data set, due to some error or measuring variability.
The median of the data without outlier is calculated as:
First, data is arranged in the ascending order: 105, 108, 109, 113, 118, 121, 124
Median =
= 4th term
= 113
The median of the data with outlier is calculated as:
First, data is arranged in the ascending order: 61, 105, 108, 109, 113, 118, 121, 124
Median =
= (109 + 113) ÷ 2
= 111
Therefore, the outlier decreased the median.
