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.

A confined aquifer has a specific storage of 2.4 x 10-S ft and a thickness of 300 ft. How much water (in acre-ft) would it yield

Georgia [21]

Answer:

water it yield is 244290.45 ft

Explanation:

given data

specific storage SS = 2.4 × $10^{-5}$ ft

thickness b = 300 ft

water declined ΔH = 4.8 ft

radius r = 1,500 ft

to find out

How much water would it yield

solution

we know that

volume of water is

Vw = S × Area × ΔH ..............1

here S = specific storage × thickness

S = 2.4 × $10^{-5}$ × 300

S = 7.2 × $10^{-3}$

and

area = πr² = π 1,500² = 7068589.471 ft²

volume of water is

Vw = 7.2 × $10^{-3}$ × 7068589.471 × 4.8

Vw = 244290.45

so water it yield is 244290.45 ft
