Answer:
.
Explanation:
Given that,
Capacitance, 
Charge stored in the capacitor, 
We need to find the electric potential energy stored in the capacitor. The formula for the electric potential energy stored in the capacitor is given by :

Put all the values,

So, the required electric potential eenergy is equal to
.
Answer:
The minimum value is 
Explanation:
From the question we are given that
The voltage is 
The internal resistance is 
The objective of this solution is to obtain the minimum value of the voltmeter resistance for which the voltmeter reading is within 1.0% of the emf of the battery
What is means is that we need to obtain voltmeter resistance such that
V = (100% -1%) of E
Where E is the e.m.f of the battery and V is the voltmeter reading
i.e V = 99% of E = 0.99 E = 7.425
Generally
E = V + ir
where ir is the internal potential difference of the voltmeter and
V is the voltmeter reading
Making i the subject of the formula above



Now the current is constant through out the circuit so,

Where
is the value of voltmeter resistance
Hence 

Answer:
A motorcycle moves 5km in 10 minutes(10×60s=600 seconds)
A motorcycle moves 5/600 km in 1 second.
A motorcycle moves 1/120 km in 1 second.( 5/600 = 1/120)
