Which example describes a scientist using a model to represent a system or structure in our universe? O Colored foam balls are used to show where the planets are located in our Solar System
A microscope is used to magnify the parts of a plant cell
A test tube is used to mix two chemicals together
A stopwatch is used to time a falling object before it hits the ground

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
