Q1: The frequency of oscillation on moon as compared to that on earth, will be

ANS:B - 2.44 times less

If we interpret "2.44 times less" in the context of frequency of oscillation, it implies that the frequency on the Moon is 2.44 times smaller than the frequency on Earth. However, the term "2.44 times less" is a bit ambiguous and can be misleading. It's essential to clarify that if something is "2.44 times less" than another quantity, it means it is 2.44 times smaller than that quantity. In the context of frequency of oscillation, we know that the frequency on the Moon is actually higher than on Earth (around 66​ times more). Therefore, the phrase "2.44 times less" isn't accurate if we're comparing the frequency of oscillation on the Moon to that on Earth. It's crucial to use language precisely in scientific contexts to avoid misunderstandings or misinterpretations. In this case, saying "2.44 times less" to describe the frequency of oscillation on the Moon compared to Earth would be incorrect.
