<h3><u>Answer;</u></h3>
Efficiency = 61.54%
<h3><u>Explanation</u>;</h3>
Efficiency is given by the Formula;
Efficiency = work output/work input × 100%
Work input = Input force × distance moved by the input force
= 13 N × 0,25
= 3.25 Joules
Work output or work done by the screwdriver is 2 Joules
Therefore;
Efficiency = 2/3.25 ×100%
<u>= 61.54%</u>
Reproduction? I could be wrong though
Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls.
