What is the relationship between ecological succession and equilibrium (balance) in an ecosystem? Ecological succession leads to equilibrium in an ecosystem.
Ecological succession leads to equilibrium in an ecosystem.

Ecological succession prevents ecosystems from ever reaching equilibrium.

There is no relationship between ecological succession and equilibrium.
There is no relationship between ecological succession and equilibrium.

Ecological succession and equilibrium are the same thing.
Ecological succession and equilibrium are the same thing.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

unbalanced force

explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
