What is Kepler's 1st law of planetary motion?

Back

Kepler's 1st law states that each planet orbits the sun in an elliptical shape, with the sun at one of the foci.

Front

What does the term 'red shift' indicate in astronomy?

Back

Red shift indicates that an object in space is moving away from the observer, causing the light to shift towards the red end of the spectrum.

Front

What is the 'expanding universe theory'?

Back

The expanding universe theory posits that the universe is continuously expanding, which is evidenced by the red and blue shifts observed in distant galaxies.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which plants convert carbon dioxide and water into glucose (sugar) and oxygen using sunlight.

Front

What shape is the Milky Way galaxy?

Back

The Milky Way galaxy is a spiral galaxy.

Front

According to Kepler's 3rd law, how does the distance of a planet from the sun relate to its orbital period?

Back

Kepler's 3rd law states that the square of a planet's orbital period is directly proportional to the cube of the semi-major axis of its orbit.

Front

What is the significance of the Hubble Space Telescope?

Back

The Hubble Space Telescope has provided invaluable data and images of distant galaxies, helping to advance our understanding of the universe.

Front

What is a galaxy?

Back

A galaxy is a massive system that consists of stars, stellar remnants, interstellar gas, dust, and dark matter, bound together by gravity.

Front

What is the difference between a 'blue shift' and a 'red shift'?

Back

A blue shift indicates that an object is moving towards the observer, while a red shift indicates that it is moving away.

Front

What are the main components of photosynthesis?

Back

The main components of photosynthesis are sunlight, carbon dioxide, and water, which are converted into glucose and oxygen.
