Final answer:
A thin wedge has a greater mechanical advantage than a thick wedge of the same length in physics.
Step-by-step explanation:
In physics, a thin wedge has a mechanical advantage (IMA) that is greater than a thick wedge of the same length. This is because the IMA of a wedge is calculated by dividing the length of the blade by its width. A thin wedge has a smaller width compared to a thick wedge, resulting in a larger IMA.
For example, if we have a thin wedge with a length of 10 cm and a width of 1 cm, the IMA would be 10. On the other hand, if we have a thick wedge with the same length of 10 cm but a width of 5 cm, the IMA would only be 2. This means that the thin wedge has a greater mechanical advantage than the thick wedge.
