Work is defined as being completed when an object shifts as a result of an applied force. It is calculated by multiplying the force exerted by the distance moved as a result of that force. It can be represented as: W = Force x distance
W = 84 J = F (7.0 m)
F = 12 N
I hope this provides clarity.
The potato does not increase in size because it is only a segment of the plant. Water absorbed from the soil is taken up by the roots and transported to other parts like leaves, but the potato itself does not directly absorb water from the soil.
