what is the energy convesionsthat occur when you use a washing machine?

Well, a good place to start would be to look at how a washing maching
works. You will need to know what parts are inside it.

This sounds a lot like someone's homework question (and a good one
too, you have a smart teacher) so I'll just suggest that you start by
looking at the forms of energy that go into the unit and follow thair
path to the componets that might produce sone kind of output or
action, which would require energy.

If no one has answered this, I will post a through breakdown in a few days.
