Step 1: Understanding Circular Shapes and Motions.
A circular shape or motion follows a round path. Moving objects like the electric fan, eye ball, and cycle ring all follow circular paths. However, water falling from a tap follows a vertical path and is not circular.
Step 2: Verifying the Options.
- Option (1): A moving electric fan has circular motion.
- Option (2): The black eye ball moves in a circular motion.
- Option (3): A cycle ring is circular.
- Option (4): Water falling from a tap follows a downward, non
-circular motion.
Conclusion:
Therefore, the correct answer is (4) Water falling from a tap.
Find the number of triangles in the given figure.
Find the unknown frequency if 24 is the median of the following frequency distribution:
\[\begin{array}{|c|c|c|c|c|c|} \hline \text{Class-interval} & 0-10 & 10-20 & 20-30 & 30-40 & 40-50 \\ \hline \text{Frequency} & 5 & 25 & 25 & \text{$p$} & 7 \\ \hline \end{array}\]
Two concentric circles are of radii $8\ \text{cm}$ and $5\ \text{cm}$. Find the length of the chord of the larger circle which touches (is tangent to) the smaller circle.
