What else can I help you with?
Why does the night sky appear to move in a circular pattern?
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.
Is the earth's orbit around the sun a circle on an ellipse?
The Earth's orbit around the sun is an ellipse, not a perfect circle. This means the distance between the Earth and the sun varies slightly throughout the year, causing the change in seasons. The orbit is slightly elliptical due to gravitational interactions with other celestial bodies and not a perfect circle.
Why is the sun linght reaching the earth yellowish?
It's as a result of the light passing though our atmosphere - and the same reason that the sky is blue !
Which planets rotate?
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.
Is a tornado also known as a twister?
Yes, though scientists rarely, if ever, us the term "twister."
If the skin is cut or broken an infection can result from microorganisms in the what?
On the skin, even though its more likely to happen from the air if this for your biology homework.
What will happen if you hang in air with a rope attached to aeropalne and the aeroplane is not moving anywhere?
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.
What are the types of circle?
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).
Does the Arctic Circle pass though more land than the Antarctic Circle?
Yes.
Do all chords of a circle pass through the center of a circle?
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.
What is a chord that passes though the center of a circle?
The diameter
How do tornadoes destroy?
The rapidly rotating wind and the debris it carries destroys structures though sheer force.
What is the name of a device that has a rotating center pin hard to explain do have a picture though?
Disk? top? gyroscope?
What continent does the Antarctic circle pass though?
Antarctica I think? :)
What line type connects 2 ends of a circle?
There are no ends to a circle. A chord connects 2 ends of an arc though.
Is the base of a cone a circle?
Yes, though an oval could be as well, i guess that there would be an individual word for that though.
Do all radii of a circle have equal length?
Yes. Make sure you mean circle and not ellipse or something though because then the answer would be no.
