Arock is pushed out of a six-story window that is 60 feet above the ground. what energy changes occur as the rock falls to the ground? a) the potential energy of the rock is destroyed as it falls. b) the potential energy of the rock is transformed into kinetic energy. c) the kinetic energy of the rock is transformed into potential energy.

B) The potential energy of the rock is transformed into kinetic energy.

Step-by-step explanation:

Our understanding of Physics tells you the potential energy due to the rock's position in the gravitational field is transformed into kinetic energy as the rock gains speed (and loses height).

Comment on the problem

There are additional effects not accounted for by this simplified answer, including thermal effects, radiation effects, and sound effects. (In this new age, there can also be energetic effects in dimensions we're not accustomed to considering, including emotional or other effects on—or due to—consciousness.)

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
