Explanation:
Where is diagram? no point A and point B given
Answer: a) Twice Chuck's
Explanation:
If the angular speed is constant, as the merry - go -round is a rigid body, so the distance between two points must remain the same, it is needed that the points farther the center, move faster than the ones closer to it.
There exists a relationship between tangential and angular speed, as follows, that relates the definitions of linear and angular speed, and the angle definition:
angle = arc / radius ⇒ Δθ/Δt = Δs/Δt / r ⇒ ω = v/r ⇒ v = ω. r
If ω is constant, v is directly proportional to r, distance to the center (radius in a circular platform), so if r is twice for Andrea, her tangential speed must be twice Chuck's.
Star Wars uses science and technology<span> in its settings and storylines, although its main focus is not necessarily on science. The component of the Star Wars movies which is possible according to our current understanding of physics is their interstellar travel.

According to them, when hit in space by a blaster, the crafts should continue moving in the same direction as the impact rather than falling downwards as the effects of gravity would not apply while in orbit. </span>
