Answer:
The joule (/dʒaʊl, dʒuːl/ jowl, jool; symbol: J) is a derived unit of energy in the International System of Units.

Well, it would mean that you would research the topic and look at its background info to see if it has reliable sources to prove your hypothesis. I hope this helped!
The types of meteorites are iron, stone and iron-stony
meteorites. The stony-iron meteorites account for less than 2% of all known
meteorites. They comprised of roughly equal amounts of nickel-iron and stone
and are divided into two groups: pallasites and mesosiderites. The answers are
only B and C
That depends on what its speed was at the beginning of 5 seconds,
and on what exactly happened to it.
If it got pushed off of the window sill and fell to the ground below,
then the answer would depend on how high the window sill is.
If the flower pot kept falling for the whole 5 seconds, then its speed
would be <em>49 meters per second</em> at the end of the 5 seconds. That's
because here on Earth, gravity increases the speed of falling things
by 9.8 meters per second for every second they fall.
Naturally, this answer is only true if the window sill is more than
122.5 meters above the ground ... about 402 feet, or 40 floors.
If it's lower than that, then the flower pot hits the ground in less
than 5 seconds, and its speed at the end of 5 seconds is zero.
By the way ...
-- It makes no difference how much the flower pot weighs.
All objects fall with the same acceleration, and hit the ground
at the same time.
-- 5 kilograms is a mass, not a weight.
