Greg and Shawn are studying for a physical science test. Greg thinks that the kinetic energy of an object depends on the height
Ludmilka [50]
It should be mass and speed so they are both incorrect because the height doesn’t mean much, but what matters is how heavy the object is, and how fast it’s going to go.

the difference between these two measurements: 60 m and 60.00 m How many sig figs does each contain? Clearly explain which digit
tensa zangetsu [6.8K]

This problem is providing two measurements, 60 m and 60.00 m and asks for the difference in the significant digits, accuracy, uncertainty, whether they are the same or not and how they differ.

<h3>Significant figures:</h3>

In chemistry, the use of significant figures is crucial, because they define the most appropriate way to report a measurement. Thus, we can say that the more decimals a measurement has, the more accurate and the less uncertain it is. Also, if no decimal places are present, tracking zeros are not significant.

In such a way, one can conclude that 60 m has just one significant figure (0 does not count) whereas 60.00 m has four  (there is a decimal making all zeros significant), 60.00 m is more accurate as more decimal places are reported. On the other hand 60 m is the more uncertain as less decimals contribute to its accuracy.

In addition, we say they can be the same measurement, as long as they represent the same idea, sixty meters, the thing is 60.00 m is more accurate yet they refer to the same measurement.
