The answer is C is the velocity is the same then the acceleration is also the same.
Answer:
The average current will be "17.69 nA".
Explanation:
The given values are:

q = 9.2 pC
Time,
t = 0.52ms
The equivalent circuit of the cell surface is provided by:

Or,
⇒ 
On substituting the given values, we get

Answer:
The constriction causes the mercury column to break under tension, leaving a vacuum between the bottom of the column and that in the bulb, and the top of the column stays still at the position reached in the body - a "peak hold" system.
The kinetic Energy has to be the same as the Energy with which the spring was stratched:
1/2×m×v^2=1/2×D×s^2
Ekin=1/2×440×0.3^2= 1/2×440×0.09=19.8. ( Of course, the kinetic Energy is normally Not calculated Like this , but in this case both Formulas have the Same solution so you can Wright it Like This)
By the way, if the spring Had Not reached its Natural length yet, you wouldnt be right if you calculate it Like above, because a Part of the Energy is still in the spring : Espring=Ekin+Espring2
Answer:
momentum formula = Mass × Velocity
