A. An axe
B. A knife
C. A faucet handle
D. A lightbulb
Answer:
A wedge is a simple machine that involves a triangular-shaped object used to separate or lift objects. An axe and a knife involve a wedge, while a faucet handle and a lightbulb do not.
A wedge is a simple machine that consists of a triangular-shaped object used to separate or lift objects by applying force to two sides, creating a splitting action. Among the items given, an axe and a knife involve a wedge. An axe has a wedge-shaped blade used to split wood, while a knife has a sharp edge that acts as a wedge to cut through materials. A faucet handle and a lightbulb do not involve a wedge as they do not rely on the same principle of separation or lifting.
So, next time you see an axe or a knife, remember that they are working with wedges to get the job done efficiently!
