Question

assume a comet is traveling at a constant velocity in deep space. why would it speed up as it approaches our solar system?
the gravitational force fields of the sun and planets in the solar system accelerates it.
an object under no other outside influences naturally speeds up.
the solar system happens to be in the area of the comets orbit where it normally speeds up.
s comets speed is influenced by the length and make - up of the tail it exhibits.

Explanation:

Según la ley de la gravitación universal de Newton, los cuerpos con masa se atraen mutuamente. Cuando el cometa se acerca al sistema solar, el sol y los planetas, que tienen masa, crean campos de fuerza gravitacional que lo aceleran.

Answer:

The gravitational force fields of the sun and planets in the solar system accelerates it.
