Answers
Given : a) Acceleration due to gravity = 9.8 m/s^2 Taken readings: 9.65, 9.7, 9.6, 9.7, 9.95, 9.75
b) The length of the object is 16.825 cm. Taken readings: 16.50, 16.8, 16.775, 16.75, 16.82
To Find : Accuracy and precision
Solution:
Accurate measurement is the measurement closer to true value
precision is the closeness of the measurements to each other
9.65, 9.7, 9.6, 9.7, 9.95, 9.75
9.75 is accurate as it is closer to 9.8
9.65 , 9.95, 9.75 are precise as have 3 significant figures
16.50, 16.8, 16.775, 16.75, 16.82
16.82 is accurate as it is closer to 16.825
16.775 is precise as it has 4 significant figures
