PLS HELP ASAP<br> decribe the importance of agriculture of the people in central america
sasho [114]

Their progress and wealth is highly dependent on the harvests, and the price of grain. They probably have to import some industrial products and if they had a bad year (weather, other catastrophies, poor technology) they can't get the necessary amount of industrial products in exchange for their surplus e. g. in grain. There are so many standards and requirements about the quality of food production that no country can survive solely on agriculture without high quality technology (machines, unharmful fertilizers, research-based breeding, etc.).

P and S waves from an earthquake travel at different speeds, and this difference helps locate the earthquake "epicenter" (where
Studentka2010 [4]

Answer:

(a) Since both P and S wave travels the same distance, so it can be written as:    Δx = V₁t₁ = V₂t₂,

Where, V₁- Speed of S wave

            V₂- Speed of P wave

            t₁- time taken by S wave

            t₂- time taken by P wave

Therefore, t₁ > t₂ (since, time taken by S wave is longer than P wave)

⇒ t₁ = t₂ + 1.5 min

⇒ t₁ = t₂ + 90 sec

⇒ V₁ (t₂ + 90 sec) = V₂ (t₂)

⇒ V₁t₂ + V₁ (90 sec) = V₂ (t₂)

⇒ V₂t₂ - V₁t₂ = V₁ (90 sec)

⇒ t₂ (V₂- V₁) = V₁ (90 sec)

⇒ t₂ = {V₁ (90 sec)} ÷ {(V₂- V₁)}

⇒ t₂ = {5.5 × (90 sec)} ÷ {(8.5 - 5.5)}

Therefore, t₂ = 165 sec

Since, Δx = V₁t₁ = V₂t₂

Now, Δx = V₂t₂ = (8.5 × 165 sec)

⇒ Δx = 1402 km

Therefore, Δx is approximately 1400 km (this means that the earthquake occurred at a distance of about 1400 km from the recorded seismic station)

(b) No, Only seismic station is not sufficient to detect the epicenter of an earthquake. Seismologists and geologists usually use the triangulation method in order to determine the exact location of the epicenter. This is possible by the use of three seismographs that are placed at three different locations nearby to that earthquake occurring position.

How do dwarf planets differ from planets?
TEA [102]

Answer:

they do orbit the sun but they are farther away, they are very small, the dwarf planet Pluto is around the size of a moon, and I wouldn't say they have a clear  path because dwarf planets don't normally have a clear path... they are normally around or are inside the outer asteroid belt of a solar system

Nata [24]

Hello


Answer: They faced economic punishment (A)


Reason: the rest of the options are all rewards that they allegdly would receive if they broke the law. This makes no sense, people are punished for breaking the law, therefore option A is the most logical out of your choices.


Hope this helps
