14 degress difference? Even you could work this out. Go check it out. Is two AC units involved here? Check the large pipe at the outside condenser units. Both should be very cold and dripping water where exposed to the open air. Not so? Problem found already.
It is certainly possible. All you need is a the second circle to have a radius which is less than 20% of the radius of the first.
It is set in an Urban setting with modern technologies
3/4 a second
Hogwarts is the main setting of the second book.
3/4 of a second
The main setting is camp half-blood. second Olympus.
Hogwarts is the main setting of the second book.
6 degrees/second
the setting is in the same time as equlipe but it is in a house in seattle
90 degrees. (360 degrees in a clockface, takes 60 seconds to cover all of them. So the second hand covers 6 degrees per second (360 divided by 60). Now multiply 6 degrees per second by 15 seconds - i.e 6 x 15 = 90
6 degrees. There are 360 degrees in a full circle, and therefore for every second the hand moves through one sixtieth of a circle.
Milliseconds. That is one tenth of a second.
