Final answer:
When a rope is under tension and fixed at both ends, it forms a straight line.
Step-by-step explanation:
When a rope is under tension and fixed at both ends, it forms a straight line. This is because the tension in the rope makes it pull in opposite directions at both ends, creating a tension force along its length.
In this case, the rope does not form a curve, loop, or zigzag pattern.
An example of a rope under tension and fixed at both ends is when you hold each end of a rope tightly and stretch it out.
