Hello.
The answer: C. amount of charge on the source charge
The field lines all represent the movements of field charges. The more crowded the field lines or the more density of electric field the higher is the magnitude of the source charge.
Have a nice day.
The period of the wave is determined as 0.083 seconds.
<h3>What is period of a wave?</h3>
The period of a wave is the time taken by a particle of the medium to complete one vibration.
<h3>Period of the wave</h3>
The period of the wave is calculated as follows;
T = 1/f
where;
- T is the period of the wave
- f is frequency of the wave
T = 1/12
T = 0.083 seconds
Thus, the period of the wave is determined as 0.083 seconds.

Answer:
How to Test Hypotheses
State the hypotheses. Every hypothesis test requires the analyst to state a null hypothesis and an alternative hypothesis. ...
Formulate an analysis plan. The analysis plan describes how to use sample data to accept or reject the null hypothesis. ...
Analyze sample data. ...
Interpret the results.
Work done is the distance a force acts over.
So, the work done here is 9.0N * 3.0m = 27 J
Temperature difference is required, so i’m guessing - a. thermometer - would be required to check that temperature.
