What is tire creep, and is it important?
Tire creep is the tendency of the tire to rotate slowly around the wheel hub as a result of a millisecond landing friction on the tire before wheel spin occurs.
Yes, it is important because if there is too much creep the tire can tear out the inflation valve and cause the tire to burst.

Where does the wing stall first on a typical SEP Aircraft (Cessna, Tecnam, ...)?
Where does the wing stall first on a typical SEP Aircraft (Cessna, Tecnam, ...)?
At the wing root. This is a property of rectangular wings, but it's also common to find close to the wing root devices that make it so that the wing root stalls first.
What is the speed of sound at sea level according to ISA?
What is the speed of sound at sea level according to ISA?
662 kts
Local speed of sound = 39 x √(Temperature in Kelvin)
15°C in Kelvin is (15 + 273) = 288
So the local speed of sound = 39 x √288 = 662 kts
