Answer:
Electric potential, 
Explanation:
It is given that,
The magnitude of electric field, 
Distance between automobile engines that consists of metal conductors, 
Let V is the magnitude of the potential difference between the conductors. The relation between the electric field and the electric potential is given by:



So, the magnitude of the potential difference between the conductors is
. Hence, this is the required solution.
Truer words were never spoken.
The "speed of light" is also the speed of radio, the speed of microwaves,
the speed of heat, the speed of X-rays, etc.
Answer:
Sodium is stored under paraffin oil
Explanation:
Group 1 metals are known to be very highly reactive. The chemical reactivity of the members of the group decreases down the group.
Sodium reacts violently with water and upon exposure to the atmosphere. As a result of this, it must be stored under paraffin oil.
