Answer:

Kepler's second law of planetary motion

Explanation:

Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the sun. It states that a line between the sun and the planet sweeps equal areas in equal times. Thus, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.

<u>Answer: </u>

The experiment most likely demonstrates Kepler's first law of planetary motion.

<u>Explanation: </u>

  • The law of elliptical orbits given by Johannes Kepler states that the planets that revolve around the sun form an elliptical orbit. He clarifies that shorter the orbit, the lesser is the time taken by the planet to complete the revolution.
  • The same principle seems to be applicable here in the experiment done by the students. As the distance of the rubber stopper from the finger goes on decreasing, the time taken by the rubber stopper to complete a revolution is decreased (and the speed is increased).

Answer:

Time was ego-centered, but reversed from Western cultures (i.e. the future is indicated by pointing backward and the past is indicated by pointing forward).

Explanation:

The Aymara, an indigenous group in the Andes highlands around Bolivia, Chile. They are said to have a time concept that is different from our own. Certain novel studies were made scientists to uncover the facts that the Aymara consider the past to be ahead and the future behind them. Time was mapped with the properties of space.
