Answer:
1) Δx = 0.16 m / s²
, Δx = 9.72-9.8 = 0.08 m / s²
2) e% = 1.63%
, , e% = 0.816%
3) 1e% = 0.04
Explanation:
The fractional error in a quantity is the absolute error between the accepted value of the quantity and the percentage error is the fractional error per 100
In this case, it is not indicated which is the measured experimental value of pi, suppose that a value of 3.142 is measured
fractional error
e = (ax - ax_average) / x_average
e = (3.142 - 3.1416) / 3.1416
e = 1.27 10⁻⁴
the percentage error is
% = e 100
% = 1.27 10-4 100
% = 1.27 10⁻²%
1) Δx = 9.96-9.8 = 0.16 m / s²
Δx = 9.72-9.8 = 0.08 m / s²
2) the percentage difference
x = 9.96 m / s2
e% = (9.96 - 9.80) / 9.80 100
e% = 1.63%
x = 9.72 m / s2
e% = (9.72 -9.80) / 9.80 100
e% = 0.816%
3) the mean value is
x_average = (x1 + x2) / 2
x_average = (9.96 + 9.72) / 2
x_average = 9.84 m / s2
e% = (9.84 - 9.80) / 9.80 100
1e% = 0.04
