Answer:
Since cold air settles and warm air rises, the tape is 'carried' up by the warm updraft. That's why you can enjoy the cold breeze of the fan. That's why the calendar pages are flipping back

Answer:
Difference in pressure
Explanation:
You may have studied fluid dynamics where according to relationship we get that when a fluid is moving it's pressure decreases. So, when the air in front of calendar moves it's pressure is less than that of air behind the pages and due to that difference it moves forward. This is the same effect due to which a ball swings.
Hope this helps (:
