AI Thread Summary
A day on the Moon lasts approximately 29.5 Earth days, which is referred to as a "moonth." The discussion also highlights the importance of knowing the diameters of the Earth and Moon, as well as the distance between them, to calculate how much larger Earth appears from the Moon compared to the Moon's appearance from Earth. The circumference of a circle with a radius equal to the Earth-Moon distance can help in understanding the relative sizes. Participants encourage using textbooks or online resources for accurate information. Overall, the conversation emphasizes the need for basic calculations and understanding of lunar and terrestrial dimensions.

if anyone could help with either of these questions, it would be greatly appreciated, thank you (:

1) how long does a day on the moon last and why?
2) how many times larger does the Earth look if you were on the moon,compared to seeing the moon from earth? (provide calculation)

thanks a lot!
(:

Have you done anything on this yourself? I entered "a day on the moon" into google and got the answer quickly. (It is about a "moonth"!) And it is probably in your textbook.

As for the second question do you know the diameters of the moon and the earth? Do you know the distance from the Earth to the moon? You could probably look those up in your textbook or on google.

What would the circumference of a circle, with radius equal to the distance from the Earth to the moon be? What part of that would the diameters of the Earth and moon be? Do you see why that will give you your answer?

If that's not a typo, then that's a terrible joke! And I love it!

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
