A voltage appears between the ends of the wire. If the ends of the wire are connected, or if there is a conductor between them, then a current flows in the wire.
Answer:
Explanation:
We know that weight of an object on Earth is,
Thus,
where,
m = mass of an object, which is constant and is independent of gravity
g = acceleration due to gravity on Earth
On the new planet, gravity = a
Thus the weight of the object on the new planet will be
