One scientist did an experiment with a meter stick and pencil. The steps of the experiment are listed below. Hold a meter stick
Marina CMI [18]

Answer:

Parallax would be most effective in measuring distances to stars which are close to the Earth.

Explanation:

In the experiment,

  • The parallax shift would decrease as the pencil would move further away from the scientist's eye, so option 1 would be invalid.
  • the size of the pencil remains constant, so option 2 would be invalid.
  • the parallax shift can be observed when the pencil has objects in the background to provide relation, that is to say, the shift of the pencil when seen relative to background objects; therefore, if we assume that the pencil is a star nearby to the Earth, and the background objects are stars that are further away, then the shift of, and thus, distance to the nearby star can be easily observed.

rewona [7]

Answer: The speed of the earth as it travels around the sun is 67,000 m / ph (107,000 km / h).

Explanation:

The orbit around the sun forms an ellipse and it takes approximately 365.25 days to fully around the orbit, because of that on earth the seasons are experienced throughout the year, as the earth recedes or gets closer to the sun. In addition to the orbit around the sun, the earth rotates on its own axis in about 24 hours giving rise to day and night.

I hope this information can help you.
