A tomato by itself wouldn't ahve any voltage.
But it's kinda acidit so if you stuck say a piece of copper and a piece of zinc in it, it'd act as a crude battery and you'd probably get a voltage.
Potato is not a solution.
first place a potato which is carved slightly inwards in the salt solution. it adsorbs the solution slowly and the level of the solution decreases.now place the pin at the potato
Starch is not a solution.
Potato chips are solids.
This is because the potato, which is mostly water, is in a hypertonic solution (a solution with less water and more solute --here, sucrose-- than the potato). Since the solutions want to reach equilibrium (equal amounts of sucrose and water in both the solution and the potato), water diffuses out of the potato and sucrose diffuses into it. The potato loses its water weight, and sucrose doesn't replace the weight lost, the potato weighs less.
The potato core would decrease because the water would leave the cells, causing the water potential to go down.
This depends on the concentration of the salt solution. If the water potential of the salt solution is greater (less concentrated) than the cell sap of the potato cells, water would move into the potato cells, increasing the size of the potato strip. If the water potential of the salt solution is lower (more concentrated) than the cell sap of the potato cells, water would move out of the potato cells in the salt solution, decreasing the size of the potato strip.

No.

In sugar solution the potato cube absorb the solution , but in distilled solution the cube do not absorb it.
Because of osmosis the water in the potato will move into the hypertonic solution causing the potato to lose weight.
