<span>The correct answer is a. seismograph. This is the instrument used to detect and measure seismic waves. During an earthquake the infromation is recorded on a seismogram, which is the seismograph's record of earthquake waves. The GPS would monitor and measure how far a tectonic plate moves with respect to time. </span>
Answer:
2.72×10^-7
Explanation:
velocity = frequency × wavelength
2.05×10^8=7.55×10^14 wavelength
wavelength = 2.05×10^8/7.55×10^14
wavelength = 2.72×10^-7
Answer:
F=k*x or
k is the spring constant, in Newtons per meter (N/m), and x is the displacement of the spring from its equilibrium position. The spring constant, k, is representative of how stiff the spring is. Stiffer (more difficult to stretch) springs have higher spring constant
