Kepler's first law states that planets orbit the sun in a path called a(n)
a. area.
b. period.
c. ellipse.
d. parabola.

Ellipse option C

Explanation:

According to Kepler's first Law :

The orbit of a planet is an ellipse with the Sun at one of the two foci.

with an eccentricity of approximately 0.015.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

force tends to be low and long diustance masses are high
