You are visually tracing the orientation of a T-shaped connector as it is rotated counter-clockwise to fit into a matching slot. The long stem of the 'T' initially points to the right (3 o'clock position). Arrange the following positions of the T-stem in the chronological order they appear as the piece undergoes a continuous 270-degree counter-clockwise rotation.
- 1The long stem points straight up (12 o'clock position).
- 2The long stem points to the left (9 o'clock position).
- 3The long stem points straight down (6 o'clock position).
Cevap
The correct sequence tracks the counter-clockwise rotation of the stem from the right (3 o'clock): first it points up (12 o'clock), then left (9 o'clock), and finally down (6 o'clock).
Starting from the right (3 o'clock position), a counter-clockwise rotation moves the piece opposite to the hands of a clock. The first quarter-turn positions the stem pointing up (12 o'clock). The second quarter-turn positions it pointing left (9 o'clock). The third and final quarter-turn positions it pointing down (6 o'clock), successfully completing the 270-degree movement.
