Front

What is the mean orbital radius of Saturn in AU?

Back

9.5 AU

Front

What is the period of Saturn’s orbit around the Sun in Earth Years?

Back

29.28 Earth Years

Front

What does Kepler's First Law describe?

Back

The elliptical shape of all orbital motion in space.

Front

What hypothesis states that the sun and planets developed from the same cloud of gas and dust?

Back

Nebular hypothesis.

Front

In which diagram is the gravitational pull on the Earth's oceans greater?

Back

Diagram B.

Front

What type of tide occurs at 9:30 a.m. if the tide is high?

Back

High tide.

Front

What is the formula to calculate the period of a planet's orbit?

Back

T^2 = a^3 (where T is the period in Earth years and a is the mean distance in AU).

Front

What is the significance of Kepler's Second Law?

Back

It states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.

Front

What is the main difference between high tide and low tide?

Back

High tide occurs when the water level is at its highest, while low tide occurs when the water level is at its lowest.

Front

What is the role of gravity in the formation of the solar system?

Back

Gravity pulled together gas and dust to form the Sun and planets.
