Thank you for that exciting news bulletin.
Here are a few more to keep you up to date:
-- The armistice has been signed, as of November 11.
-- Lindy made it !
-- The Japanese have surrendered to General Macarthur.
-- Secretary Clinton has won in the popular vote.
The best answer between the two options would be the second choice B) FALSE.
We'll assume that the whole scene takes place on Earth.
So the acceleration of gravity is 9.8 m/s² downward.
a). Gravity makes anything fall 9.8 m/s faster every second.
That's the same thing as rising 9.8 m/s slower every second.
If it takes 2.9 seconds to reach its maximum height, then
it must have started out rising at (9.8 x 2.9) = 28.4 m/s.
b). The ball left the bat at 28.4 m/s.
After 2.9 seconds, its speed was zero. (That's why it started falling.)
It's average speed during the climb was
1/2 (28.4 + 0) = 14.2 m/s .
It rose straight up at an average speed of 14.2 m/s for 2.9 seconds,
so it reached a maximum height of
(14.2 x 2.9) = 41.2 meters .
IV - The miracle grow (since this does not change based on the dv)
DV- The height of the plant (since it depends on how much/ wether miracle grow was added.)
Control- The control would be the plant without any miracle grow
Hypothesis- If miracle grow is added to the plant, then it will grow taller because it will give the plants the nutrients it needs.
