Answer:

(4) period of revolution

Explanation:

• The rotational period of the planet around the sun is directly impacted by the closeness and the far spaced planet as the gaseous planet have a slow speed of rotation as compared to the terrestrial planets  as they are far than the rocky planets like the Jupiter and the Saturn and the other gas planet that rotates slower on their axis.

• As the mercury takes about 0.2 years to revolve and the that of the Jupiter is 11.9 years and that of the Saturn is 29.5 years and that of the Uranus is 84 years and that of the Neptune is about 164.8 years which is equal to about 60,190.03 days the longest thus the planet sped of rotation directly depends on the planet.

• Hence this shows that the planet that are near are less dense as the far off planets

Final answer:

Geodetic datums are a set of reference values that map the Earth's complex spherical shape onto a flat surface using a coordinate system. They function like a grid system in a city layout by defining circles on the sphere, helping us to calculate coordinates to easily locate points on Earth using latitude and longitude.

Explanation:

Geodetic datums are indeed a set of reference values that specify the coordinate systems used for calculating coordinates of points on the earth. This is the first step towards creating map projections, which are an essential function in the field of geography and geometry.

Imagine trying to position coordinates on a sphere much like a city layout, like Manhattan or Salt Lake City. Defining a geodetic datum on a sphere is more complex than on a flat surface. Think of it as trying to define circles on the sphere that serve the same purpose as the rectangular grid you see on city maps.

For example, in creating an accurate map, a mapmaker needs a way to uniquely identify the location of major features on the map, like cities or natural landmarks. This is achieved using a geodetic datum, which divides the surface of the Earth into a grid, and each location can easily be found using its latitude and longitude coordinates.

On a two-dimensional graph, the independent variable and the dependent variable can represent any two properties of a system. The horizontal axis corresponds to the independent variable, and the vertical axis corresponds to the dependent variable. And this is the basic principle applied in geodetic datums.
