Question

Marine biologist, Igor Vladimir, is conducting research on the 25-40 cm in diameter, Aurelia aurita, commonly known as the moon jellyfish. He is trying to determine how much water is needed to propel the translucent jelly, that is capable of only limited motion, and drifts with the current, even when swimming. Which of the images, A or B, most likely represents a measurement this scientist made? Justify your answer.

Answer 1

Answer:

Image A

Explanation:

The most likely image that represents the measurement of the scientist would be image A.

Image A indicates the shape that water would form in a tube. Due to the adhesive force between the molecules of water and the wall of the tube, the surface of water usually forms a concave shape in a tube. Hence, the lower meniscus of the water is usually read in a tube which is what image A represents.
