Answer:
i) Q' = Q/2.
ii) If the wires to the battery are disconnected, the amount of charge on the plates remains constant, and the voltage across the plates remains the same.
Explanation:
i) The formula for capacitance is given as
C = A/d
Where d = separation between the plates
The formula for the charge stored is given as
Q = CV
Q = AV/d
When "d" is doubled, the charge stored "Q" becomes half because Q is inversely proportional to the separation between the plates, d.
Thus, Q' = Q/2.
ii) If the wires to the battery are disconnected, the amount of charge on the plates remains constant, and the voltage across the plates remains the same.
Answer:
Refraction are in parts or are reflected brokely, like light against aluminum. While a reflection, is exact. Like a mirror.
Compute the work done on the table:
<em>W</em> = <em>Fd</em> = (320 N) (32 m) = 10,240 J
Divide this by the given time duration to get the power output:
<em>P</em> = <em>W</em>/∆<em>t</em> = (10,240 J) / (150 s) ≈ 63.3 W
