Passage II
When a sphere falls through air, the sphere is subjected to a drag force, F, that resists its motion. F depends on the spheres diameter, D; the air temperature, T; the sphere's speed, V; and atmospheric pressure.
The table below gives F, in newtons(N), on a sphere falling through air near Earth's surface, for various combinations of D, in meters (m); T, in degrees Celsius (°C); and V, in meters per second (m/sec). For each combination, air pressure is 1 atmosphere.
8. Based on the table, F will be greatest for which of the following D, T, and V ?
Your Answer is
Correct Answer is J
Explanation
From the table, it can be drawn that the larger D is, the larger F is; the smaller T is, the larger F is; the larger V is, the larger F is. So choose the group with the largest D and V and the smallest T
