Final answer:
The recommended position for rollers to achieve full volume is horizontal. The rotational analog of distance is rotational angle. To cover the maximum distance, launch a projectile at a 45-degree angle, and among objects spinning with the same angular velocity, a vinyl record has the highest speed at its edge.
Step-by-step explanation:
The Correct Answers
For the question asking about the recommended roller position for full volume, the correct answer is: a) Horizontal. This would provide the most lift at the base of the hair, hence delivering full volume.
Regarding the rotational analog of distance, the correct answer is: a) Rotational angle. Just as linear distance measures how far you've moved in a line, the rotational angle measures how far you've rotated around a circle.
When considering the optimum angle for a projectile to cover maximum distance, the correct answer is: b) 45°. According to physics, launching at a 45-degree angle takes advantage of both the horizontal and vertical components of the launch velocity to maximize range.
The object spinning at the same angular velocity that would have the highest speed at its edge, is the: c) Vinyl record. Larger radii at the same angular speed translate to higher linear speed at the edge.
