Question 5

A student is investigating the terminal velocity of a spherical bead falling through a column of viscous oil. They measure the terminal velocity of the bead five times and obtain the following results:

  • 0.78 m s-1
  • 0.81 m s-1
  • 0.52 m s-1
  • 0.79 m s-1
  • 0.82 m s-1

What is the most appropriate mean value for the terminal velocity of the bead calculated from these data?

A

0.74 m s−10.74\text{ m s}^{-1}0.74 m s−1

B

0.80 m s−10.80\text{ m s}^{-1}0.80 m s−1

C

0.79 m s−10.79\text{ m s}^{-1}0.79 m s−1

D

0.64 m s−10.64\text{ m s}^{-1}0.64 m s−1
