If the niches of two organisms overlap, A. The organisms may have to compete directly.
B. both organisms will disappear from the habitat.
C. the two organisms will always form symbolic relationship.
D. one organisms usually migrates to a new habitat.

i wanna say it’s between b and d, leaning more towards b.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

the closer the planet is to the sun, the larger the gravity

  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.
