Answer:
2 J
Explanation:
A charged capacitor of capacitance 
with energy of 7.54 J, is connected in parallel with another capacitor 
, so the charge is equally distributed between them.
(a) The energy stored in the capacitor before it being connected to the other capacitor is:
The energy stored in the electric field is the sum of the energies of the two capacitors:
since the charge equally distributed, 
= 
= 
. and since they are connected in parallel the potential difference on both of them is the same
:
hence,
Answer:
Explanation:
The horizontal distance covered by the ball in the falling is only determined by its horizontal motion - in fact, it is given by
where
is the horizontal velocity
t is the time of flight
The time of flight, instead, is only determined by the vertical motion of the ball: however, in this problem the vertical velocity is not changed (it is zero in both cases), so the time of flight remains the same.
In the first situation, the horizontal distance covered is
in the second case, the horizontal velocity is increased to
And so the new distance travelled will be
So, the distance increases linearly with the horizontal velocity.
