Pure water is a colorless, odorless liquid with no molecules
except H₂O in it. You can buy it at the supermarket, or make
it at home if you have the equipment and know how to use it.
At the supermarket, it's sold in gallon jugs, marked "Distilled
Water".
It turns out that pure water tastes bleah, and you would not
want to drink it for very long.
The Earth's water cycle is constantly purifying our water.
When the sun warms the ocean's surface and evaporates
water, what evaporates and rises into the atmosphere is
pure water. The pollutants don't evaporate. The clouds,
the rain, and the rivers are self-purifying. Another example
of a process of nature that makes life possible here.
The junk is collecting in the oceans. We're lucky that the oceans
have such huge volume that we haven't been able to significantly
pollute that entire layer of the Earth and kill off all sea life yet.
But we're working on it.
Vfinal = Vinitial + at
Vinitial = 0
a = 9.8 m/s^2
t = 8s
Vfinal = 0 + 9.8 * 8
ANSWER: 78.4 m/s
The answer is a constraint
B) in Physics, charge conservation is the principle that the total electric charge in an isolated system never changes. The net quantity of electrical charge, the amount of positive charge minus the amount of negative charge in the universe is always conserved.
This question involves the concepts of equilibrium and Newton's third law of motion.
The support force will be "1 pound" for the empty bucket and the support force will be "6 pounds" after pouring water into it.
- According to the condition of equilibrium, the sum of forces acting on a stationary object must be zero. Hence, the support force of the table will be equal to the total mass of the bucket.
- According to Newton's Third Law of Motion every action force has an equal but opposite reaction force. Hence, the support force will be a reaction force to the weight of the bucket.
Therefore, the support force in each case will be equal to the total mass of the bucket:
Case 1 (empty bucket):
<u>support force = 1 pound</u>
<u></u>
Case 1 (water poured):
support force = 1 pound + 5 pound
<u>support force = 6 pound</u>
<u></u>
