Answer:
4.25 J
Explanation:
Given that
mass of plastic ball = 11 g
Mass of plastic ball = 0.011 kg
velocity of ball = 29 m/s
We know that from work power energy theorem
We know that kinetic energy of moving mass given as
Now by pitting the values
KE= 4.25 J
So the work done on the ball is 4.25 J
Answer:
<em>20.08 Volts</em>
Explanation:
<u>Parallel Connection of Capacitors</u>
The voltage across any two elements connected in parallel is the same. If the elements are capacitors, then each voltage is
They are both the same after connecting them, thus
Or, equivalently
The total charge of both capacitors is
We can compute the total charge by using the initial conditions where both capacitors were disconnected:
Now we compute Q1 from the equation above
The final voltage of any of the capacitors is
