How might geologist in china and australia geologist in japan determine where an earth quake has occurred a)by using seismic data from several locations scientist can determine the epicenter of an earth quake b)chinese and australian scientist can go to japan to them analyze their sesmic data c)chinese and australian scientist can study the damage caused in their own countries. d) these scientist can determine the earthquakes location by the shking they feel at their locations.

Option: A is correct.

( by using seismic data from several locations scientist can determine the epicenter of an earth quake).

Step-by-step explanation:

" The size or magnitude of earthquakes is determined by measuring the amplitude of the seismic waves recorded on a seismograph and the distance of the seismograph from the earthquake "

Hence option A is correct. ( by using seismic data from several locations scientist can determine the epicenter of an earth quake).

the 4th choice is the correct one

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
