Answer:
If you know that that free fall acceleration g on the Moon is about 6 times less than on the Earth, it gives you the answer: on the Moon the same pendulum will have a period about √6≈2.45 longer than on the Earth.
Answer: If, enough evidence accumulates to support a hypothesis, it moves to the next step (known as a theory) in the scientific method and becomes accepted as a valid explanation of a phenomenon.
Explanation: a scientific theory is the framework for observations and facts.

Explanation:
(a) The period of a wave is the time required for one complete cycle. In this case, we have the time of five cycles. So:
(b) The frequency of a wave is inversely proportional to its period:
(c) The wavelength is the distance between two successive crests, so:
(d) The speed of a wave is defined as:
