Plz help hurry Part 1: Describe the mass and surface temperature of the supergiant stars.

Part 2: Explain where on the HR diagram you would expect to find a supergiant star based on its physical properties. (10 points)

  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.

conservation of mass

mass before something happens = mass afterwards
