Earthquakes are measured by special machines called seismometers. Scientists use the numbers from 1 to 10 to say how strong an earthquake is. This number system is called a scale, or a magnitude scale. Magnitude means how big or strong something is. Higher numbers mean stronger earthquakes.This is illustrated in Figure 2.5.1 2.5. 1. The scale on the left is a cm scale because the smallest value you know is in cm, and marker (arrow) is clearly greater than 1 and less than 2 centimeters, and so would be reported as 1.6cm, or maybe 1.7cm (as you report all certain values, plus the first uncertain value).Magnitude is a measure of how bright or dim an object appears in the sky. Notice that we used the term 'appears' in the definition. It is because magnitude, as we usually mean it, does not tell how bright that object really is. It merely refers to bright it seems to be.At t = 5, the bike is moving right at 5+ (2) (5) = 15 m/s. 3. Use this formula to find average velocity.
