Final answer:
When a wire ligature is cut, the cut end or pigtail is often bent for various purposes in different contexts such as electrical wiring and orthodontics.
Step-by-step explanation:
In Physics, when a wire ligature is cut, the cut end or 'pigtail' is often bent. This bending can serve different purposes depending on the context.
For example, in electrical wiring, the pigtail may be bent and connected to another wire using a wire nut to create a secure electrical connection. In other applications, such as in orthodontics, the pigtail may be bent to allow for easier manipulation or attachment to braces.
