Answer:
Scientists can use the wobble to work the planet's mass and the distance from the star.
Explanation:
Detecting a star's wobble is one way to find out if there are planets orbiting it, this happens because the planet is “tugging” on it, the gravitational force from the star acts to keep the planet in orbit, and the gravitational force from the planet acts to move the star as the planet orbits. Scientists can use the wobble to work the planet's mass and the distance from the star.
Considering this information we can conclude that the correct answer is distance to the planet and mass of the planet.

Answer:
Option (C)
Explanation:
CO₂ is one of the main green house gases on earth. A small increase in its concentration can lead to significant changes on earth. When the incoming solar radiations are incident on the earth's surface, some of the energy is absorbed by the atmosphere and the earth's surface. And some of the energy from the land surface after absorption is released into the atmosphere in the form of infrared radiations. The escaping of these radiations from earth is directly dependent on the concentration of CO₂. An increase in the amount of CO₂ will not allow these IR radiations to be removed, and this will result in the global rising of the temperature, leading to catastrophic changes.
Thus, the correct answer is option (C).
Maintains in a range are in a chain are series in a line.
The correct answer is C. In a chain or series in a line
