Question

extend it! earths distance from the sun, and its inertia, along with the suns gravitational pull, all work together to keep the earth orbiting in a specific path and a specific speed (30 km/s or about 70,000 mph). select the statement(s) which theorize what might happen to the earth if the mass of the sun doubled. more mass means stronger gravitational pull by the sun. being closer to the sun would effect life on earth as we know it in negative ways. the orbital speed of earth would most likely increase. earth would most likely be pulled in closer to the sun by its stronger gravity.

Explanation:

According to Newton's law of universal gravitation, gravitational force is proportional to mass. A doubled - mass Sun would have a stronger gravitational pull. This stronger pull would likely draw Earth closer and increase its orbital speed. Also, being closer to the Sun would have negative impacts on life on Earth due to increased radiation and heat.

Answer:

All of the statements are correct:

• More mass means stronger gravitational pull by the Sun.
• Being closer to the Sun would affect life on Earth as we know it in negative ways.
• The orbital speed of Earth would most likely increase.
• Earth would most likely be pulled in closer to the Sun by it's stronger gravity.
