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:

It is a completely false statement that to form a negative ion, an atom will <span>give up an electron to gain stability. The correct option among all the options that are given in the question is the second option. Negative ion has more electrons and so it would be wrong to say that it will give up an electron. I hope the answer has helped you.

The kinetic theory of gases is a simple, historically significant model of the thermodynamic behavior of gases, with which many principal concepts of thermodynamics were established. The model describes a gas as a large number of identical submicroscopic particles, all of which are in constant, rapid, random motion
Answer:
It hit Earth like a really long time ago, so many rocks and soil should have been piled on top of the crater because of wind, rain, etc.
Also, it is really deep and really old so when it is old, it gets less visible to the naked eye.
Answer:
A derived quantities is terms of the 7 base quantities via a system of quantity equations which are called SI derived units.
Explanation: there you go:)
