Question

a person chews 3kg ice in 1 minute has he performed any work​.explain​

Answer 1

Answer:

No, he has done no work at all

Explanation:

Something can only be considered as a work if the doer moves from its place in performing it, even if a person is holding a heavy box, it is not considered a work until and unless he moves atleast a bit.

Ex: A person moving 1cm North

     A person jogging

So, the example of a person chewing ice has not performed any work. Setting aside that it is literally impossible to chew that much ice, he can do that from one place itself, so no work is done.

Hope this helps...
