Earth travels around the Sun each year in an elliptical path, as opposed to a perfect circle. This means that the speed of Earth and its distance from the Sun change over the course of a year. What does this say about the magnitude of the centripetal acceleration of Earth over the course of a year?

Step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
