Final answer:
A motorized pump can supply pneumatic power to the MAC, serving as a critical component in systems such as power brakes and bulldozers by compressing air to exert force.
Step-by-step explanation:
The piece of powered equipment that can supply pneumatic power to the MAC (which likely refers to a mechanical apparatus or system) is a motorized pump. In systems that require pneumatic power, such as power brakes or heavy construction equipment like bulldozers, the motorized pump is responsible for compressing air, which then exerts force through the system to perform various tasks. The pump is a critical component in these systems as it supplies the required force to make them operational.
