The answer is the first one: Pineal gland.

Explanation for each option:

  1. Pineal gland: This gland is known for producing melatonin, a hormone that helps regulate sleep-wake cycles and circadian rhythms. It is directly involved in the establishment of 24-hour circadian rhythms, making it the correct answer.

  2. Thyroid gland: This gland primarily regulates metabolism and does not play a direct role in establishing circadian rhythms.

  3. Hypothalamus: While the hypothalamus is involved in regulating various bodily functions, including sleep, it is not the primary gland responsible for establishing circadian rhythms. It does, however, work closely with the pineal gland.

  4. Pituitary gland: This gland is known as the "master gland" because it controls other glands in the endocrine system, but it is not directly responsible for circadian rhythms.

In summary, the pineal gland is the correct answer as it plays a crucial role in regulating circadian rhythms through the production of melatonin.

In April 1974, John Massis of Belgium managed to move two passenger railroad cars. He did so by clamping his teeth down on a bit that was attached to the cars with a rope and then leaning backward while pressing his feet against the railway ties. The cars together weighed 700 kN (about 71 tons). Assume that he pulled with a constant force that was 2.1 times his body weight, at an upward angle θ of 32 degrees from the horizontal. His mass was 81 kg, and he moved the cars by 1.0 m. Neglecting any retarding force from the wheel rotation, find the speed of the cars at the end of the pull.
