How can I tell if the source is AC or DC

A 24 V battery is connected to the primary input of a transformer having a turns ratio of 8. The voltage seen at the secondary output is:

Now how can I tell if the source is AC or DC from this question?

Good question. If the battery is made from electrochemical cells, it's DC. And I've never heard of an AC source referred to as a "battery". If they meant AC, it is a really weird way to word the question.

It was a bit of a trick question from my teacher...luckily I got it right...the answer is zero volts since a battery would be considered a DC source...therefore no output voltage
