The magnitude r, measured on the richter scale, of an earthquake of intensity i is defined as requalslog startfraction upper i over upper i 0 endfraction , where upper i 0 is a minimum intensity used for comparison. if the intensity of an earthquake was 10 superscript 6.08times upper i0, what was the magnitude on the richter scale?

R = 6.8

Explanation:

Given data:

Richter scale

where R - magnitude of earthquake of Richter scale

I - quake's intensity

- minimum intensity earthquake

Plugging all information in the equation to get Richter's scale

R = 6.8

tube or goog will be great resources to find the answer to the question that you're asking

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
