Question

Orient the cards in the "cross" position as shown in the drawing (iii). Place your pencil point at X. With the cards motionless, carefully draw a line on the loose card (B) along the cut-edge and directly away from you. The line you drew represents a path that is ________.

a) Straight
b) Curved
c) Zigzag
d) Spiral

Answer 1

The line you drew represents a curved path.

Step-by-step explanation:

The line you drew represents a path that is curved. This can be seen in the example of a ball slid straight toward the edge of a rotating merry-go-round, where the path of the ball curves to the right in the rotating frame. Similarly, when drawing a line on the loose card along the cut-edge and directly away from you, the line will follow a curved path.
