For point A:
For point B:
For point C:
For point D:
For point E:
therefore C_A has the maximum capacitance and max energy same energy is dir proportional to C for the same J
Answer:
1st law:. An object will remain stationary or moving at a constant speed unless an external force is applied upon it
2nd law: Force = Mass × Acceleration
3rd Law: Every action has an equal and opposite reaction

Answer: 7,000 ohms
Explanation:
From the equation of ohms law V= IR
V=21 volt
I = 3 MA = 3.0×10^-3 A
So by evaluating, we have.
V= IR
21= 3.0×10^-3 × R
Then R = 21/3.0×10^-3
R= 7,000 ohms//.
Answer:
Less strongly attracted.
Explanation:
Potassium and sodium are both alkali metals. That means that they have the ability to be able to gather more valence electrons. They will both gain a positive particle. The potassium electron is less attracted because of the fact that now the sodium has a positive chargem and the electron has a negative charge.
Answer:
The two forces acting on the object are weight due to gravity pulling the object towards earth, and drag resisting this motion. When the object is first released, drag is small as velocity is low, so the resultant force is down. This means the object accelerates towards earth.
