-- The acceleration due to gravity is 32.2 ft/sec² . That means that the
speed of a falling object increases by an additional 32.2 ft/sec every second.
-- If dropped from "rest" (zero initial speed), then after falling for 4 seconds,
the object's speed is (4.0) x (32.2) = <em>128.8 ft/sec</em>.
-- 128.8 ft/sec = <em>87.8 miles per hour</em>
Now we can switch over to the metric system, where the acceleration
due to gravity is typically rounded to 9.8 meters/sec² .
-- Distance = (1/2) x (acceleration) x (time)²
D = (1/2) (9.8) x (4)² =<em> 78.4 meters</em>
-- At 32 floors per 100 meters, 78.4 meters = dropped from the <em>25th floor</em>.
The 5 points are certainly appreciated, but I do wish they were Celsius points.
Answer:
the answer is (d + 1) (d + 7)
I would go with c due the fact that water has tendencies to flow, meaning it will runoff and majority of the water will run off, it couldn’t be a because the fact that the grass and plant will absorb what they need. D clearly is too vague for such a question. B would be the only contesting answer but I feel c is the stronger choice because evaporations is a longer process and because of that only little amounts of water will evaporate while majority of it will become runoff due to hills, mountains, storm drains, slopes, etc.
<span>the information gathered in a scientific investigation is called : Data
Data consists of qualitative measurement (which cannot be counted with numbers) and quantitative measurement (which could be counted with numbers), and the scientists rely on these datas to create a correct conclusion regarding the question that experimented within the investigation</span>
