Most likely MedBTW what options are you all doing?
Quanta, Astro or med?

I think you forgot to put the ^ symbols for the radius and mass of the earth, but I'll try solve it now.How come there are no question left for me to answer!? Btw I like the idea of this thread and it would have been great if some people could have moved their discussions somewhere else as you are kind of spamming.
Heres my question and this should be really easy. So like calculate the period of a satellite orbiting the earth at an altitude of say 700,000 km. Okay so the radius of the earth is 6.38 × 106 m and the earth’s mass is 5.97 × 1024 kg. Work it out people and show your full working.
I will look at the solutions tomorrow morning maybe.
Oops thats so stupid of me how could I have not realised that!I think you forgot to put the ^ symbols for the radius and mass of the earth, but I'll try solve it now.
Just apply Keplers 3rd Law.Edit:
Is orbital period one of Kepler's laws?
That's pretty late into the Space topic so I doubt that many, if not any, people know it yet.Just apply Keplers 3rd Law.
r^3/T^2 = G*M/4*Pi^2That's pretty late into the Space topic so I doubt that many, if not any, people know it yet.
But the formula is something like:
T^2 = (4 x pi^2 x r^3)/G*M
From google.
That's the same formula that I said. By the way what is the 'r' component?r^3/T^2 = G*M/4*Pi^2
My yearlies ended weeks ago so been studying since then. So quite ahead on Space.
Orbital radius.That's the same formula that I said. By the way what is the 'r' component?
I know. 'r' component is orbital radius as intergrand already pointed out. Not sure if we have to go into a lot of the theory behind calling it orbital radius.That's the same formula that I said. By the way what is the 'r' component?

And about the link that eyeseeyou posted, remember that if you do the option Astrophysics, you need to know most content from the cosmic engine.What do I need to know from the prelim course for the HSC course?
^BUMPA crate of supplies for a scientific expedition to Greenland is being dropped by plane. When the supplies are dropped, the plane is travelling at 40 m/s horizontally at a height of 50 m. Sadly the parachute fails to open and the package falls to the ground at 9.8 m/s^2. Find the horizontal distance travelled by the package as it falls given that it hits the ground right at the feet of the scientific party.

How did you get this answer?127.78m
Quote the formulas of motion (should be obvious) set y as -50 to get t --> sub into the x-motion.How did you get this answer?
