Question

A shovel performs several different functions. One of these is that it gives mechanical advantage as a lever. When does it act like a lever? (1 point)

when the soil is lifted with the dirt at the end of the shovel and a lifting force at the handle

when the shovel is in the dirt and you push down against the end of the shovel, making it pivot

when you push the shovel downward into the dirt and a small force allows you to push down into the dirt easily

when you step up onto the shovel with both feet to use your body weight

Answer 1

when the shovel is in the dirt and you push down against the end of the shovel, making it pivot

Reason: that setup creates a fulcrum (where the shovel contacts the ground), an effort at the handle, and a load at the blade — the defining parts of a lever.
