Question

choose the correct answer
what is a device made up of two or more simple machines?
a simple machine
a compound machine
net force

Explanation:

To determine the correct answer, we recall the definitions of machine types. A simple machine is a basic mechanical device, while a compound machine is defined as a device made up of two or more simple machines. "Net force" is a physics concept related to forces, not machines. So the device made of two or more simple machines is a compound machine.

Answer:

B. A compound machine (assuming the options are labeled with A for "A simple machine", B for "A compound machine", and C for "Net force" based on typical multiple - choice formatting for this question)
