Question

An animation of four planets orbiting around the sun is shown below. Based on this animation, which of the following statement(s) is/are \textbf{TRUE? \quad [This question contains an animated GIF image.]}

• A. When Planet Blue completes 2 orbits, Planet Green will complete 1 orbit.
• B. When Planet Blue completes 3 orbits, Planet Brown will complete 2 orbits.
• C. When Planet Green completes 1 orbit, Planet Red will complete 2 orbits.
• D. When Planet Red completes 4 orbits, Planet Brown will complete 2 orbits.

Hint:

For orbit-based animation questions: \begin{itemize} \item Focus on relative angular speeds, not distances alone, \item Count full revolutions over equal time spans, \item Inner orbits always complete faster than outer ones. \end{itemize}

Answer 1

The Correct Option is A, B, C

Step 1: From the animation, observe that planets closer to the sun complete orbits faster, while those farther away take longer, consistent with relative angular speeds shown. \bigskip Step 2: Compare orbital speeds by tracking how many times each planet completes a full revolution over the same time interval. \bigskip Step 3: \begin{itemize} \item Statement A: Blue completes two orbits in the same time Green completes one — True. \item Statement B: Blue completes three orbits while Brown completes two — True. \item Statement C: Red completes two orbits in the time Green completes one — True. \item Statement D: Brown completes fewer than two orbits when Red completes four — False. \end{itemize} \bigskip Final Answer: \[ \boxed{\text{A, B and C}} \] \bigskip
