Final answer:
Wedge a (11" long and 4" high) generates the greatest amount of force.
Step-by-step explanation:
Wedges are simple machines that are used to split objects apart. In this case, the force generated by a wedge is determined by its length and height. The formula used to calculate the force generated by a wedge is Force = Length * Height. Therefore, the wedge with the greatest force would be the one with the highest product of length and height.
Let's calculate the products for each wedge:
- Wedge a: 11" * 4" = 44 square inches
- Wedge b: 9" * 4" = 36 square inches
- Wedge c: 7" * 4" = 28 square inches
- Wedge d: 5" * 4" = 20 square inches
Therefore, wedge a (11" long and 4" high) generates the greatest amount of force.
