Answer:
D. The moon is closer to Earth than the sun.
Explanation:
Tides are formed as a consequence of the differentiation of gravity due to the moon across to the Earth sphere.
Since gravity variate with the distance:
(1)
Where m1 and m2 are the masses of the two objects that are interacting and r is the distance
For example, see the image below, point A is closer to the moon than point b and at the same time the center of mass of the Earth will feel more attracted to the moon than point B. Therefore, that creates a tidal bulge in point A and point B.
The Sun tidal force contributes to the tidal force of the moon over the earth making high tides higher and low tides lower.
However, even when the sun is more massive than the moon, it is farther away from the Earth than the moon. So, it is clear by equation 1 that the moon's gravity has a greater effect on Earth's oceans than the sun's gravity.
Answer: v = 3.57×10^6 m/s; R = 4.42×10^-3m; T = 7.78×10^-9 s
Explanation:
Magnetic force(B) = 4.60×10^-3 T
Electric force(E) = 1.64×10^4 V/m
Both forces having equal magnitude ;
Magnetic force = electric force
qvB = qE
vB = E
v = (1.64×10^4) ÷ (4.60×10^-3)
v = 3.57×10^6 m/s
2.) Assume no electric field
qvB = ma
Where a = v^2 ÷ r
R = radius
a = acceleration
v = velocity
qvB = m(v^2 ÷ R)
R = (m×v) ÷ (|q|×B)
q=1.6×10^-19C
m = 9.11×10^-31kg
R = (9.11×10^-31 * 3.57×10^6) ÷ (1.6×10^-19 * 4.6×10^-3)
R = 32.5227×10^-25 ÷ 7.36×10^-22
R = 4.42×10^-3m
3.) period(T)
T = (2*pi*R) ÷ v
T = (2* 4.42×10^-3 * 3.142) ÷ (3.57×10^6)
T = (27.775×10^-3) ÷(3.57×10^6)
T = 7.78×10^-9 s
Answer: 40
Explanation:
I believe this is correct. I did 60/1.5 to get 40/mph
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.

Hope this helps!
