Answer

Brief Explanations:

Variable stars are classified into extrinsic (changes due to external factors like eclipses) and intrinsic (changes due to internal processes like pulsation). The sun's gravity provides the centripetal - force that keeps the planets in their orbits around it.

Answer:

  1. C. Extrinsic and intrinsic
  2. C. Keeps the planets orbiting around the sun
