72.5 degrees
both september and march because they both contain equinoxes which is when the sun is at the highest altitude
That completely depends on your latitude ... where you are on earth north or south relative to the equator. -- If your latitude is 23.5° south ... on the Tropic of Capricorn ... the noon sun is directly overhead on December 21. -- If you are more than 23.5° south of the equator, then the noon sun is (113.5° - your south latitude) above the northern horizon. -- If you are between the equator and 23.5° south latitude, the noon sun is (66.5° + your south latitude) above the southern horizon. -- If you are north of the equator, the noon sun is (66.5° - your north latitude) above the southern horizon. Notice that this means that anywhere north of 66.5° north latitude ... the Arctic Circle ... the sun doesn't rise at all on that day, even at noon.
That depends on the latitude from which you are observing Polaris.At the Equator (0 latitude) Polaris will be tangential to the northern horizon (0 degrees of altitude)At 52 degrees north the altitude of Polaris will be 52 degreesTherefore At the North Pole (90 latitude) Polaris will be overhead (90 degrees of altitude).
For an observer at latitude 35 degrees, the highest the sun can ever be in his sky is roughly 31.5 degrees above the horizon.
At the autumnal equinox, the Sun is directly over the equator, so the Earth's axial tilt would be an irrelevant data point. Champaign-Urbana, IL is at 40 degrees 7 minutes north latitude, so the "local apparent noon" elevation of the Sun would be 49 degrees 53 minutes. If you were asking this question about the summer solstice, then the Earth's axial tilt would become relevant. If this was 40 degrees, then the Sun would be essentially directly overhead at noon.
On the Summer Solstice, June 21, the Sun is at about 23.5 degrees north. If you are at 50 degrees north, then at noon ("Local Apparent Noon", when the Sun reaches its highest point in the sky) on June 21, the Sun will be at an altitude of 66.5 degrees above the southern horizon.
47 degrees.
First, we need the "transit altitude" of the celestial equator, at 80 degrees north. That's 90 - 80 degrees = 10 degrees. At noon (local apparent noon) the Sun's altitude will be: 10 degrees + the Sun's declination. That's the altitude of the Sun's "upper culmination". At "midnight" (the Sun's "lower culmination") the Sun's altitude will be: the Sun's declination - 10 degrees. So, the difference in altitude is 20 degrees. The Sun is 20 degrees higher at noon.
the tilt goes towards the sun, the seasons chang from winter to summer

The sun can never be higher in the sky at the north pole than it is in the sky at New York City. The highest solar noon elevation at the north pole is 23.5 degrees, on June 21. On the same date, the solar noon elevation in Manhattan's Central Park is about 73 degrees.
The observer must be 15.5 degrees south of the Arctic circle, so 51.1 degrees north approximately.

Kazakhstan...
It's about 66.5 degrees above the northern horizon.
You might be anywhere along the Tropic of Cancer, where the latitude is 23.44 degrees north.
