Answer:
C. a current that rapidly switches direction
Explanation:
An audio speaker is an electronic device that converts electrical signals into sound energy (waves). The alternating current flowing into the audio speaker is typically used to generate sound waves.
Hence, what causes the poles of the electromagnet in an audio speaker to repeatedly switch directions is due to a current that rapidly switches direction. The electromagnet is placed in a position where it experiences a constant magnetic field as a result of the presence of a permanent magnet. Like every magnet, the electromagnet and the permanent magnet interact with each other; opposite sides attract while like sides attract. This interaction generates a force, causing the alternating current to constantly reverse the poles of the electromagnet in an audio speaker to repeatedly switch directions.
I would say D. But l may be incorrect. Al bots are not made for games, but are made for information.
Sorry l can't be much of help, but l do hope that I did help you out in a way.
The place value can be used to convert a binary number, such as 11010010, into decimal form: 11010010 = 1 x 27 + 1 x 26 + 0 x 25 +1 x 24.In light of the aforementioned, the base-4 number system has 4 digits: 0, 1, 2, and 3. Any 2-bit number can be represented by a single base-4 integer since a 2-bit number can only represent one of the values 0, 1, 2, or 3.
<h3>What does base 4 mean?</h3>
- Base-4 is a quaternary number system. Any real number is represented by the digits 0, 1, 2, and 3.
- In light of the aforementioned, the base-4 number system has 4 digits: 0, 1, 2, and 3. Any 2-bit number can be represented by a single base-4 integer since a 2-bit number can only represent one of the values 0, 1, 2, or 3.
- The four digits of Quaternary (Base 4) are 0 through 3.
- Binary code 4 is 100. In a binary number system, we only use the digits 0 and 1 to represent a number, as opposed to the decimal number system, which uses the digits 0 to 9. (bits).
