What is true about the foci of a planet it elliptical orbit?
A) earth is located at one focus
B) the sun is located in the center of the orbit
C) the sun is located at one focus
D) earth is located in the center of the orbit
I put c but I don’t know if it is right. Can someone tell me if I am pls
1.Elliptical
2.The sun is located at one focus.
3.The planet's orbital speed changes as it moves closer and farther from the Sun.
4.1.59 AU
5.3.49 Years
Bts_eats_dogs omg i love u, u saved my life :)
Bts_eats_dogs youre amazinggggg
I agree.
Yippee 🥳
All are 100% correct, thanks much!
The correct answer is C) the sun is located at one focus.
To understand why this is true, let's first discuss what foci are in the context of an elliptical orbit. An ellipse is a geometric shape that resembles a flattened circle. In an elliptical orbit, the planet follows this elliptical path around the sun.
An ellipse has two foci (plural of focus). Foci are special points within the ellipse that help define its shape. The sum of the distances from any point on the ellipse to the two foci is always constant.
In the case of a planet's elliptical orbit, one of the foci will always be the location of the sun. This means that the sun is located at one of the foci, and not in the center of the orbit.
Option A) "earth is located at one focus" is not correct. The Earth doesn't orbit itself, but rather orbits around the sun.
Option B) "the sun is located in the center of the orbit" is also not correct. The center of the orbit is not necessarily the location of the sun in an elliptical orbit.
Option D) "earth is located in the center of the orbit" is also not correct. The planet's position in the orbit can vary, but it is not located in the center of the orbit.
Therefore, option C) "the sun is located at one focus" is the correct answer.
