Q:- What will be the weight of a person on moon? Will it be less or more than his weight on the earth?
Ans:- As the acceleration of the gravity of the moon is one-sixth that of the earth; therefore the weight of a person on the surface of the moon will be one-sixth of his actual weight on earth.

RESISTANCE AND RESISTIVITY
The resistance of a conductor is the obstruction offered by the conductor to the flow of electric current through it.
Resistance (R) of a conductor is defined as the ratio of the potential difference (V) across the ends of the conductor to the current (I) flowing through it i.e.
The S.I unit of resistance is Ohm. Where 1 Ohm= 1volt/1ampere=1V/1A
Thus 1 ohm is the resistance of a conductor through which a current of 1 ampere flows when a potential difference of 1 volt is applied across the ends of the conductor.
