None of the given options are correct.
The correct answer is: Due to static electricity, the charged comb attracted the neutrally charged water.
When the student combed his hair, the comb became charged with static electricity. Water molecules are polar, meaning they have positive and negative ends. The charged comb creates an electric field that polarizes the water molecules, causing them to align with the electric field. This alignment creates an attraction between the charged comb and the neutrally charged water, causing the water's path to change.
writ me a simple beat It should be in a simple meter, such as The symbol for three-four time is the numeral three over the numeral four. or four-four time and eight measures long (two four-measure phrases).
Make sure there is at least one flat or sharp in the key signature.
You need to also include at least one dynamic marking, such as a piano or forte.
Unfortunately, as a text-based AI model, I am unable to create or generate auditory content like beats. However, I can provide you with a simple music notation that adheres to your requirements.
Here is a simple beat in 4/4 time signature, eight measures long, with a key signature including one flat and a dynamic marking:
```
Key Signature: Bb Major (1 flat - Bb)
Dynamic Marking: Forte (Dynamic symbol "f")
Beat:
```
Measure 1:
[Quarter Note - Bb] [Quarter Note - Bb] [Quarter Note - Bb] [Quarter Note - Bb]
Measure 2:
[Quarter Note - Eb] [Quarter Note - Eb] [Quarter Note - Eb] [Quarter Note - Eb]
Measure 3:
[Quarter Note - F] [Quarter Note - F] [Quarter Note - F] [Quarter Note - F]
Measure 4:
[Whole Note - Bb]
Measure 5:
[Quarter Note - Bb] [Quarter Note - Bb] [Quarter Note - Bb] [Quarter Note - Bb]
Measure 6:
[Quarter Note - Eb] [Quarter Note - Eb] [Quarter Note - Eb] [Quarter Note - Eb]
Measure 7:
[Quarter Note - F] [Quarter Note - F] [Quarter Note - F] [Quarter Note - F]
Measure 8:
[Whole Note - Bb]
Please note that this is just a simple representation of a beat in musical notation and does not include any specific rhythm or tempo indication. It's always better to perform or play the beat on an instrument to get a complete musical experience.
To determine why the water's path changed when the student put the comb near the faucet, we need to understand the concepts of induction and conduction.
Induction is a process in which an object with an electric charge creates an electric field in its surroundings. When an electrically charged object is brought near a neutral object, the charges in the neutral object get rearranged due to the influence of the electric field. In this case, the student's comb became charged through friction with the hair, and when brought near the faucet, it induced a separation of charges in the water.
Conduction, on the other hand, is the transfer of electric charges from one object to another through direct contact. In this situation, conduction would only occur if there was a direct physical contact between the charged comb and the water.
Now, looking at the options provided, we can eliminate the choices involving conduction since there is no direct contact mentioned between the charged comb and the water. Hence, the correct explanation should involve induction.
The correct response is:
Due to induction, the charged comb attracted the neutrally charged water.
