lubrictation on the moving parts
Whatever moving object you have in mind the ways to reduce resistance are: Streamlining - remove projections if possible and make smooth and round if not Use low friction materials Reduce cross-sectional area of moving object
The purpose of a voltage droop is to intentionally reduce the voltage of a device. Further information about why and when one would do this can be found on Wikipedia.
Any air moving device that has either Carulite 200 (a catalyst that turns ozone back to oxygen) or activated carbon (which requires frequent replacement / reactivation), will reduce ozone levels in the air passing through it. Odorous compounds with double carbon bonds or not-fully-oxidized sulfur will consume ozone. These would be perfumes, flatulence (sorry), rotten egg smells, and so on.
A usb cable is not a device. A USB drive would be a Storage Device and still not be an Input or Output device. A USB keyboard would be an input device and a USB printer would be an output device.
Assuming you mean a data-storage device (for use with computers) then the most clear cut answer would be a CD-ROM or a DVD-ROM, neither of which have any moving parts by themselves. The disc-reader however would have moving parts which may negate the idea of a stationary storage device.Flash memory is another form of storage which is commonly found in USB drives and small electronics. It has no moving parts.

You can reduce friction in machines in factories by using lubricants such as oils and greases on moving parts, ensuring proper maintenance and alignment of components, using high-quality materials to reduce wear, and implementing regular cleaning procedures to prevent buildup of debris. Regular monitoring and inspection of machinery is also important to identify potential friction issues early on.
A microphone would considered an input device.

Yes, it would be the storage device.Yes, it would be the storage device.
no cd is a storage device as it holds data an output device would be a monitor or speakers.
