An earthquake generates both transverse ...

An earthquake generates both transverse (S) and longitudinal (P) sound waves in the earth. The speed of S waves is about 6 km `s^(-1)` and that of P waves is about 9 km `s^(-1)`. A seismograph records P and S waves from an earthquarke. The first P wave arrives 5 minutes before the first S wave. the epicenter of the earth quake is located at a distance

A

54 km

B

540 km

C

5400 km

D

72 km

Text Solution

Verified by Experts

The correct Answer is:
C
Let `i_(s)` = speed of transverse wave and `i_(p)` = speed of longitudinal wave
`(d)/(i_(s)) -(d)/(i_(p)) = t `
`(d)/(6) - (d)/(9 ) = 5 (60 )`
d = 5400 km

Earthwuakes generate sound waves inside the earth. Unilke a gas, the earth can experience both transverse (S) and longitudinal (P) sound waves. Typically, the speed of S wave is about 4.0 km s^(-1) , and that of P wave is 8.0 kms^(-1) . A seismograph records P and S waved from an earthquake. The first P wave arrives 4 min before the first S wave. Assuming the waves travel in straight line, how far away does the earthquake occur?

Earthquakes generate sound waves inside Earth. Unlike a gas, Earth can experience both transverse (S) and longitudinal (P) sound waves. Typically, the speed of S waves is about 4.5 km/s, and that of P waves 8.0 km/s. A seismograph records P and S waves from an earthquake. The first P waves arrive 3.5 min before the first S waves. If the waves travel in a straight line, how far away did the earthquake occur?

Earthquakes generate sound waves inside the earth. In case of the earth, both transverse (S) and longitudinal (P) waves can propagate. Typically, the speed of S waves is about 4.5 km s^-1 and that of P waves is 8.0 km s^(-1) . A seismograph records both P and S waves from an earthquake. this difference helps us to find the distanec of the point of origin of the earthquake. this point is called the epicenter. Q. The reading of the time lag between the arrival of S and P waves gives us the distance of the epicenter from the location of a seismograph. the readings of what minimum number of seismographs would be necessary to pinpoint the location of an epicenter?
