Answer:
D. High frequency and short wavelengths.
Explanation:
If a wave is high in energy it will have a higher frequency.
High frequency = short wavelengths
Answer:
Anybody which is in state of rest ,will be in rest if we don't apply any external force ...
When sphere A and B are brought in contact and separated, charge on each sphere becomes [2x10^-6 + (-4x10^-6)]/ 2 = -1x10^-6 C.
That is, charge is equally separated and is the average of charges on both spheres. The reason behind equal charge on both spheres after separation is, when they are kept in contact, their potential difference becomes same.
These forces form a force pair. Use Newton's third law, and you see that the trailer pulls back at with the same force. The answer is d.
Hey there,
Density = Mass/Valume
D= 3.1/0.35
D= 8.86 g/cm3
