The capacitance of the system is
Explanation:
The capacitance of a capacitor is given by the following equation:
where
C is the capacitance
Q is the charge stored in the capacitor
V is the potential difference across the capacitor
In this problem, we have:
is the charge stored
is the potential difference across it
Substituting into the equation, we find the capacitance:

Answer:
(a) 25 m
(b) 75 m
Explanation:
Given that the jogger runs at a constant rate of 10.0 m every 2.0 seconds.
So, the speed of the jogger,
Let d be the distance covered by him in time, t s.
As distance=(speed) x (time)
So,
From equation (i)
As the jogger starts from origin, so, the distance, , also represents the position of the jogger at the time
s.
The position-time graph has been shown.
(a) From equation (ii), for t=5.0 s
So, the jogger is at a distance of 25 m from the origin.
(b) Similarly, for t=15.0 s
So, the jogger is at a distance of 75 m from the origin.
