Question

Underwater divers wear fin-like flippers on their feet to

• A. swim easily in water
• B. look like a fish
• C. walk on the water surface

Answer 1

The correct option is A

swim easily in water

Step 1: Underwater diving:

1. The practice of going underwater swimming is known as Underwater diving.
2. When diving at ambient pressure, the physiological effects of immersion in water and exposure to high ambient pressure limit the depths and durations that can be reached.
3. Humans are neither physiologically nor anatomically well adapted to the conditions of diving, so varied equipment has been designed to increase the depth and duration of human dives, as well as to allow various types of work can be done.

Step 2: Underwater divers wear fin-like flippers:

1. Swim fins enable divers to swim efficiently underwater without exerting excessive power.
2. Swim fins limit muscle action and hence oxygen consumption, allowing a diver to stay beneath the water for longer periods of time.
3. The flipper's design allows them to travel through water with ease. Swimming becomes easier as a result of this, and there is less exertion on the muscles of the swimmers.

Hence, option (A) is correct.
