In an experiment to measure the density of iron, the following data was obtained. book value is 7.86 g/cm3. one of the two sets of data is more precise, while one is more accurate. which of these two sets has the greater precision and which has the greater accuracy
(a) 7.72, 7.74. 7.73. 7.75, 7.74
(b) 7.86, 7.90, 7.78, 7.93, 7.83
which is more precise?
which is more accurate?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
