Answer:
10 V
Explanation:
The potential difference between two points is the amount of work required to carry a unit charge from one point to the other point. This would result in a potential difference between this two points.
The difference between the potential across two points B and A is 
From the image attached:

Answer:
a) V = 252 cm³
b) Vs = 72 cm³
Explanation:
a)
The volume of the water can be given by the following formula:

<u>V = 252 cm³</u>
<u></u>
b)
The volume of stone can be given by the change in volume of the water when the stone is dipped into it.

<u>Vs = 72 cm³</u>

Answer:
The velocity of the leaf relative to the jogger is 5 m/s.
Explanation:
Given that,
Velocity of jogger wrt to the ground, 
velocity of leaf wrt the ground, 
We need to find the velocity of the leaf relative to the jogger. Let it is equal to V. So, it is given by :

So, the velocity of the leaf relative to the jogger is 5 m/s. Hence, this is the required solution.
