Which of the following is a physical model of the sun? a. an equation that describes the sun’s motion b. a chart that lists the temperatures of different parts of the sun c. a computer program that shows how the sun changes over time d. a paragraph that describes the sun’s structure e. a small yellow ball that represents the sun

A. an equation that describes the Sun’s motion: It is mathematical modelling equation for sun

B. a chart that lists the temperatures of different parts of the Sun : It is thermal analysis for sun

C. a computer program that shows how the Sun changes over time : It is software or computer modelling of sun

D. a paragraph that describes the Sun’s structure : It is simple two dimensional representation for sun

E. a small yellow ball that represents the Sun : This is actual physical model for sun. A physical model is one which depicts the actual shape, position, arrangement of any actual thing. Like we can construct a physical model for subatomic particles arrangement on an atom

similarly for sun we can represent it with a small yellow ball which will be called as its physical model.
