If you are on the top of a mountain and drop an apple, it will fall
to the ground, even though the apple is gravitationally
attracted to you. Why?
Earth is larger and has a much stronger
gravitational pull
b Apples always fall down
Centrifugal forces pull the apple to the Earth and
that is stronger than your gravitational pull
None of these

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
