Answer:
The average force exerted by the water on the ground is 17.53 N.
Explanation:
Given;
mass flow rate of the water, m' = 135 kg/min
height of fall of the water, h = 3.1 m
the time taken for the water to fall to the ground;
mass of the water;
the average force exerted by the water on the ground;
F = mg
F = 1.789 x 9.8
F = 17.53 N
Therefore, the average force exerted by the water on the ground is 17.53 N.
<h2>Answer: Neptune
</h2>
The dwarf planet Pluton, <u>has the most eccentric orbit</u> (more elliptical and elongated) of all the planets, and as a consequence its orbit is "intersected" by the orbit of Neptune.
However, <u>despite this intersection, there is no collision risk between these two bodies</u>, since the orbit of Pluto is located in an orbital plane different from that of the other planets and therefore different from that of Neptune, its nearest neighbor. In addition, the orbit of Pluton is inclined on the the ecliptic plane (plane where the other planets move around the Sun).

1). The change would be due to the expansion of the speaker, so we need to know what substances comprise the speaker. #2). A speaker with a diameter of 0.055m is not too good at reproducing 8.54 KHz. (3). I believe this is a bogus question.
