Answer:
Explanation:
An elliptical orbit is defined by two points called the foci. The distance between the foci is known as the focal length. If the distance between the foci of an elliptical orbit is increased, the shape of the orbit will become more elongated, or "flattened" into an ellipse. If the distance between the foci is decreased, the shape of the orbit will become more circular.
So, if the distance between the foci points of an elliptical orbit is increased from its current value to 2.5 cm, the shape of the orbit would become more elongated, or "flattened" into an ellipse. The degree of elongation would depend on the original distance between the foci and the new distance of 2.5 cm. The more the distance is increased, the more elongated the ellipse will become. Conversely, if the distance between the foci is decreased from its current value to 2.5 cm, the shape of the orbit would become more circular.
