Why is it easier to cut something with a sharp knife than with a blunt one?

The area of the knife edge is small so pressure is greater.

The area of the knife edge is large so pressure is greater.

The area of the knife edge is large so pressure is smaller.

The area of the knife edge is small so pressure is smaller.

In science, a lever is:

a simple machine which changes the size of force you put in.

a complex machine which keeps the size of force you put in the same.

a simple machine which changes the area of force you put in.

someone about to finish school.

Which are the correct labels for the lever shown below?

X = load, Y = pivot, Z = effort

X = effort, Y = pivot, Z = load

X = pivot, Y = effort, Z = load

X = load, Y = effort, Z = pivot
