Answer:

C) proposed that the sun was the center of the solar system      

Explanation:

The Heliocentric model was proposed by Nicholaus Copernicus which describes the sun at the center of the solar system. The Earth with other planets and moons revolves around it in concentric orbits. Later, Kepler gave planetary laws which describes the planetary orbits as elliptical. Before heliocentric model, Ptolemy's geocentric model was popular which considered Earth as the center but it was proven incorrect with the Heliocentric model.

Question 11 of 11 | Page 11 of 11
KiRa [710]

Answer:

Decreases the time period of revolution

Explanation:

The time period of Cygnus X-1 orbiting a massive star is 5.6 days.

The orbital velocity of a planet is given by the formula,

                                        v = √[GM/(R + h)]

In the case of rotational motion, v = (R +h)ω

                                         ω = √[GM/(R + h)] /(R +h)

Where 'ω' is the angular velocity of the planet

The time period of rotational motion is,

                                     T = 2π/ω

By substitution,

                                      <em>T = 2π(R +h)√[(R + h)/GM] </em>

Hence, from the above equation, if the mass of the star is greater, the gravitational force between them is greater. This would reduce the time period of revolution of the planet.
