Pt Juan argues that when you burn coal, you use up the coal, and hence you use up all of its energy, and this results in a net loss of energy in the universe. How
could you fix Juan's argument? The total energy in the universe remains constant because
A. the chemical energy in the coal is converted into thermal energy
B. the kinetic energy in the coal is converted into potential energy
C. the elastic potential energy in the coal is converted into thermal energy
D. the gravitational potential energy in the coal is converted into elastic potential energy

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

  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.
