A day passes-it does that every day.
It is an ellipse. The orbits of all the planets are ellipses, though the orbit of Venus, while elliptical, is very close to being a circle.
It won't happen....But would be pretty funny and creepy if it did though!
It is a combination of how the Earth is rotating and orbiting the Sun. If you stand in one spot and look up, and start turning, everything above you will appear to be going around in a circle. This is the same effect. As the Earth orbits the Sun, stars appear to be in slightly different positions at the same time from night. At the same night each year, the stars you see are the same. Stars that are lower in the sky disappear at certain times of the year. Ones that are high overhead can be seen all year, though they also appear to circle.
Yes, though they are most common in spring and summer.
The Planet Uranus has its axis at 97.9 degees to the plane of rotation around the sun and because it takes 84 of our years to go round once, it has 42 years of light and 42 years of darkness at its poles. Pluto is the other Planet which has a similar angle of 122 degrees though I think Pluto has recently been demoted to a dwarf planet or asteroid because of its small relative size compared to other planets. Even so it has a companion moon called Charon.
On the skin, even though its more likely to happen from the air if this for your biology homework.
In the rotating frame, it can be (though it doesn't have to be). In an inertial frame, no (though it can be uniform in magnitude).
perhaps i saw that I'm displacing from my original position though it's not me which is displacing its position. it is the which is rotating that's why it seems to dispacement of mine.
In 2D, there is the regular circle and the oval. In 3D, there is the sphere (I am not entirely certain this a considered a circle though).
Yes.
No, not all chords of a circle pass though the center of that circle. Any cord that does pass through the center of the circle is called diameter of that circle.
The rapidly rotating wind and the debris it carries destroys structures though sheer force.
Disk? top? gyroscope?
The diameter
Antarctica I think? :)
There are no ends to a circle. A chord connects 2 ends of an arc though.
Area in a circle = (pi) times (square of the circle's radius)You can use any number you want to use for (pi) in that formula. The closer yourchoice is to the real value of (pi), the closer your result will be to the real area.If you decide to use 22/7 , then your result will be only about 0.04% bigger than thereal area. That's very good accuracy, and that's why a lot of people use 22/7 for (pi)even though it doesn't look very impressive.
