Recently I gave my Astronomy Olympiad. There were some questions of descriptive type. If you all don't mind I would like to discuss them here.

A satellite is 36000 Km away from the equator. What will be the maximum latitude from which the satellite can be viewed.
russ_watters said:It doesn't matter if it is stable or not - it is at 36000km right now.
I think that more than 1 arrangement is possible. And the sum should always be a constant. Probably 360 degree. Whadda say?Light passes through a box containing an arrangement of 4 plane mirrors. If the box is removed, even then light doesn't change its path. Is there more than 1 arrangments possible? What will be the sum of all the angles of incidence and reflection.
I agree on the first but disagree with the second. I can make any sum from 180* to 720*.ritwik06 said:I think that more than 1 arrangement is possible. And the sum should always be a constant. Probably 360 degree.

I have assumed that the shell is spherical. And the the space inside the shell is vacuum. Am I going in the right direction?If a shell of iron just floats inside water. Find the ratio of the outer radius to the inner radius. (Density of iron: 7.87 g/cc)
The Astronomy Olympiad is an international competition for high school students that focuses on various topics in astronomy and astrophysics. It aims to encourage students' interest and knowledge in the field of astronomy.
The questions in the Astronomy Olympiad cover a wide range of topics, including theoretical concepts, observational skills, and problem-solving abilities. They can include multiple-choice, short answer, and long answer questions.
To prepare for the Astronomy Olympiad, it is recommended to have a strong foundation in mathematics and physics. It is also helpful to practice with previous competition questions and study topics such as celestial mechanics, astrophysics, and observational astronomy.
No, you do not need to be an expert in astronomy to participate in the Olympiad. The competition is open to high school students of all levels, and the questions are designed to test both basic and advanced knowledge in the field.
To participate in the Astronomy Olympiad, you can either be selected by your school or register as an individual participant. The competition is typically held at national and international levels, with various rounds of exams and selection processes.
