Answer:
f = 96.56 Hz
Explanation:
A soda bottle can be simulated by a system of a tube with one end open and the other closed. In this case at the closed end we have a node and at the open end a maximum, so the wavelength is
λ = 4L / n
where n = 1, 3, 5, ...
for our case the speed of sound is
v = λ f
we substitute
f / v = 4L / n
calculate
290 / (340 4) = L / n
0.213 = L / n
In the exercise the value of n is not indicated, but we can assume that it is the fundamental answer, therefore n = 1
L = 0.213 m
now we can calculate the frequency of the following resonance n = 3
f = 4L v / n
f = 4 0.213 340/3
f = 96.56 Hz
-- "Tesla" is a unit for the strength of a magnetic field.
The Earth's magnetic field at the surface ... the one that makes
compasses work ... averages roughly 45 microteslas.
So 1 Tesla = somewhere around 20,000 times the magnitude
of Earth's magnetic field at the surface.
There's a smaller, more convenient unit, called the 'Gauss'.
1 Tesla = 10,000 Gauss. The Earth's magnetic field ranges
between 0.25 to 0.65 Gauss at various places on the surface.
-- Newton is a unit of force, equal to about 3.6 ounces.
1 pound of force is about 4.45 newtons.

Answer:
The student that says the phrase "travels through liquids" goes in the middle, in between the two circles in the venn diagram.
Explanation:
You are most likely to find a trench at a divergent boundary between two plates.

You don't have to but if you want to I recommend downloading this:

I'm currently in seventh grade and the assignments we are given in science is focused on earth and its layers. (because of schools closing ya know, online assignments and stuff, our teacher gave this helpful simulation sort of game)
Hope that helps! (it's basically a simulation of how plates form the way they do)
