The statements which best describe the properties of tsunami waves are these: 1. THEY HAVE LONG WAVELENGTH.
2. THEY TRAVEL AT VERY HIGH SPEED.
Tsunami typically occur as a result of sudden displacement of gigantic water masses which erupted due to earthquake that occur on the sea bed. One peculiar characteristic of tsunami is the very wide distances between its wavelengths. A tsunami is a very long wavelength waves of water, its wavelength is much more greater than that of ordinary wave and can be as much as 300 kilometer.
Wavelength is refers to the distance between two identical points on a wave, that is, between wave crests or wave troughs.
Tsunami also travels at very high speed; it can travel for a long period of time at high speed without losing much energy.
I have no idea what lesson you're talking about, but I am multilingual so I'm sure my answer can suffice for the small amount of details.
One advantage of being bilingual as a child is that, when faced with text written in a different language nobody else but you understands, you can save everyone's butt from taking out inaccurate translators for that text.
The disadvantage that follows that is the fact that people will now recognize you as that one dude that speaks every language, even if you don't. So, now, you have everybody coming up to you to translate everything they don't understand.
Another advantage is that you can read something everyone else would find disturbing (like, my graphic horror/action stories) without anybody understanding it because it's in another language.
The disadvantage that follows is that they're almost always going to be nosy brats and asking what every word means.
The last advantage I'll list is that you can get away with saying stuff. Like, "man, that woman must be on something", or, "darned drunkards", without starting up a fight with them, because, really, who's going to understand Thai way over in America? (I honestly wouldn't recommend risking it, though. Speaking of which...)
The last disadvantage here is the fact that you won't know who speaks these languages around you. For all you know, your best friend had understood every comment about the loony across the street and simply chose not to comment on it.
So, for the final conclusion, knowing different languages is great and all, but it's not that great.
The speed of the satellite in a circular orbit around the Earth is 1.32 x 10⁵ m/s.
<h3>
Speed of the satellite</h3>
v = √(GM/r)
where;
- G is universal gravitation constant
- M is mass of Earth
- r is radius of the satellite
v = √(6.67 x 10⁻¹¹ x 5.98 x 10²⁴/3.57 x 6.37x 10³)
v = 1.32 x 10⁵ m/s
Thus, the speed of the satellite in a circular orbit around the Earth is 1.32 x 10⁵ m/s.

Answer:
Horizontal distance is 1.28 + 2.04 = 3.32 m
Explanation:
Given data:
from below figure
Applying Pythagoras theorem
from Snell's law


solving for x we have

x = 1.28
Horizontal distance is 1.28 + 2.04 = 3.32 m
The impact speed will be
v^2 = 2*9.8*1.3
v^2 = 25.48
v= 5.04 m/s
