The motion of falling objects is the simplest and most common example of motion with changing velocity. The early pioneers of physics had a correct intuition that the way things drop was a message directly from Nature herself about how the universe worked. Other examples seem less likely to have deep significance. A walking person who speeds up is making a conscious choice. If one stretch of a river flows more rapidly than another, it may be only because the channel is narrower there, which is just an accident of the local geography. But there is something impressively consistent, universal, and inexorable about the way things fall.
Answer:
Explanation:
Rocks tell us a great deal about the Earth's history. Igneous rocks tell of past volcanic episodes and can also be used to age-date certain periods in the past. Sedimentary rocks often record past depositional environments (e.g deep ocean, shallow shelf, fluvial) and usually contain the most fossils from past ages.
Answer:
drugs and alcohol
Explanation:
All the others will help your body, while drugs and alcohol will only harm it .
Frequency, υ = 2.09 Hz
We know that time period, T = 1/υ
∴ T = 1 ÷ 2.09
⇒ T = 0.4784 seconds
Well, wind can change landforms by storms, and hurricains, or other things that contain air...
~~~~~~~~~~~~~
Like, over a period of time... Wind can make landforms decrease in size, by weathering.

Hope this helps! :)
