Answer 1

The cap on this water bottle has a spiral shape. When you place it on the bottle and twist, the cap pulls itself toward the bottle.

Answer 2

The machine is found to be on a water bottle cap:

Explanation:

• The cap on this water bottle has a twisting shape. Whenever you put it on the jug and wind it, the cap pulls itself toward the jug.
• team changes rotational movement over to straight movement as it goes inside an item.
• A container cap changes rotational movement over to direct movement when we turn the cap to open or to seal the jug. Thus the container cap is a screw.
• At the point when you turn the enormous handle on an entryway, a pole within discharges a hook that holds the entryway closed.It would be hard to turn the pole, on the off chance that the handle wasn't appended to it.

Hence,D is the correct option.
