The rising intonation is usually used in yes / no question
for example : are you happy ?
what happens if the falling intonation is used for the yes/no question ?
what's on the speaker's mind ?
How many people are coming?
Why are being so mean?
If you could give me an example, I would be happy to clarify. Intonation is very important though - if you get it wrong, it sounds extremely strange. There is a scene in the movie Anchorman which demonstrates this!
I'm Ron Burgundy?
