The salt makes it rise and
Gamma rays, or rather gamma radiation are most commonly used.
D) Its position changes because the unbalanced forces move the object.
Solution :
A cell that is concentrated is constructed by the same half reaction for the anode as well as he cathode.
We know,
In a standard cell,
the reduction half cell reaction is :

The oxidation half ell reaction :

Thus the complete reaction of the cell is :

cell =
