Consider two stars in orbit about a mutual center of mass. If a1 is the semimajor axis of the orbit of star of mass m1 and a2 is the semimajor axis of the orbit of star of mass m2, prove that the semimajor axis of the orbit of the reduced mass is given by a

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

mass and volume are the answers you are looking for

  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.
