The magnitude of an earthquake, measured on the Richter Scale, is M log1o T where / is the amplitude registered on a seismograph
just olya [345]

<u>Answer:</u> The magnitude rating for an earthquake causing an amplitude 10,000,000 times I_o is 7.

<u>Explanation:</u>

Richter scale is defined as the scale which expresses the magnitude of earthquake on the basis of the seismograph oscillations.

The equation used to measure the magnitude of an earthquake on Richter scale is:

M=log_{10}\frac{I}{I_o}

where

I = amplitude registered on seismograph 100 km away from seismic center = 10,000,000I_o

I_o = small amplitude

Putting values in above equation, we get:

M=\log_{10}(\frac{10000000I_o}{I_o})\\\\M=7

Hence, the magnitude rating for an earthquake causing an amplitude 10,000,000 times I_o is 7.

What is the mass in grams of 85.32 mL of blood plasma with a density of 1.03 g/mL
sveticcg [70]
<span>Well if you're looking for grams, all you need to do is cancel out units. (ml)(g/ml)=g because the ml cancels out. Thus, multiply: (85.32ml)(1.03g/ml)=...I'll let you solve this. :) Good luck! Hope that helped. When in doubt, look at the units.</span>
