Answer:
2.15% was the percent error of the 2007 measurement.
Step-by-step explanation:
To calculate the percentage error, we use the equation:
[tex]\%\text{ error}=\frac{|\text{Experimental value - Theoretical value}|}{\text{Theoretical value}}\times 100[/tex]
We are given:
Experimental value of diameter of Pluto ,2015= 2372 km
Theoretical value of diameter of Pluto, 2007 = 2322 km
Putting values in above equation, we get:
[tex]\%\text{ error}=\frac{|2372 km-2322 km|}{2322 km}\times 100\\\\\%\text{ error}=2.15\%[/tex]
Hence, 2.15% was the percent error of the 2007 measurement.
