Answer:
Low Frequency, Long Wavelength, and Low Energy Transfer
Explanation:
Radio waves are on the larger(and lower frequency) side of the electromagnetic spectrum. These longer wavelengths mean that radio waves have a lower frequency because it takes longer for larger waves to travel. Therefore, less radio waves can travel a certain distance in a minute than a wave of a shorter wavelenght(and therefore lower frequency). Radio waves are considered a low-energy transfer wave. This is because they can be used in most environments for communication, air-traffic control, and broadcasting with little to no harm to the organisms around them. Even though radio waves can be found all around us, because they don't carry much energy, we aren't harmed by the radio waves.

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.
