The only correct statement on that list is <em>choice-C</em>: If a positively charged rod is brought close to a positively charged object, the two objects will repel.
Answer:
A: The kinetic energy of the two vehicles is transferred to potential energy when it stops.
B: The more mass an object has the more kinetic energy it will have.
Explanation:
This may be the right answer for your question but if it isn't my bad.
Answer:
The pressure inside the bubble is 666.67 
Solution:
As per the question:
Radius, R = 
Now,
Given that the surface tension of the wall is the same as that of soapy water.
The air trapped inside the bubble exerts pressure on the soap bubble which is given by:
Gauge Pressure, P = 
Also, the surface tension of the soapy water, 
To calculate the pressure inside the alveolus:
Based on the given figure above, the correct answer would be option A. 2 hertz. The frequency of the wave movement during 1 second is 2 hertz. Since 2cycles/second is equal to 2 hertz. You can also get this answer by using the wave-speed equation which is <span>c=νλ. Hope this answers your question. </span>
