Hi, What are the differences between these 3 question?
are they share the same meaning?
1. What is used?
2. what has it used?
3. What does it use?
What is used- which things are required
What has it used- It requires something or things for its purpose and you want to know what/which have been consumed, or whatever, during the recent period of functioning.
What does it use - You want to know what it requires
