This question is incomplete. Here is the complete question:
Which physical law states that all orbits are conic sections?
A. Kepler's third law
B. Kepler's second and third laws
C. Newton's laws
D. Kepler's first law
Answer:
The correct answer is option D. Kepler's first law.
Step-by-step explanation:
A renowned astronomer and mathematician named Johannes Kepler established laws that characterized the movements of the planets that are part of our solar system.
Kepler's First Law states that all orbits are conic or ellipse-shaped sections, and the Sun is located in a center point within them. The planets are going to move along these ellipses, which means these sections are not going to share the same center.
Therefore, if a planet moves within an ellipse, and the Sun is only at one point, each planet will move closer and further away from the Sun in different ways, each within this ellipse, therefore the distance between the planet and the sun will change constantly.
Given this data, we can say that the correct answer is option D.
