Question

possible points 1
use the following table to order the materials from highest to lowest viscosity:

material	velocity of marble through material
2	14.5 cm/s
3	0.755 cm/s
4	3.45 cm/s

○ 4, 3, 2, 1
○ 3, 4, 1, 2
◎ 3, 1, 4, 2
○ 1, 2, 3, 4

Explanation:

Step1: Relate velocity to viscosity

Higher viscosity = slower marble speed

Step2: Sort speeds from slowest to fastest

$0.755\ \text{cm/s} < 2.54\ \text{cm/s} < 3.45\ \text{cm/s} < 14.5\ \text{cm/s}$

Step3: Map to material numbers

Slowest (3) → 1 → 4 → Fastest (2)

Answer:

3, 1, 4, 2
