Hello, I have an exercise for my DM on the rotations to do, I am in 4th grade.
Please help me!
Dm maths:
Take a representation of the Ursa Minor and the Ursa Major, constellations of stars visible to the naked eye. At night, the pole star (here named O)
is a star that does not seem to move. O is the center of rotation.
Following the rotation of the Earth, the other stars seem to revolve around
the pole star. Suppose that in one hour the stars have rotated by 50 °.
Build their image (in green) using a protractor.
Then build their image 3 hours later (i.e. at 150 ° in red) then
5 hours later (at 250 ° in blue). NOT'
they are important for assessing comprehension of the exercise.
Thank you for giving me a little of your time to help me. Thank you !
