AI Thread Summary
The discussion explores the historical significance of the number 60 in timekeeping, tracing its origins to Babylonian mathematics, which favored base-60 due to its divisibility. It also examines the implications of a slower Earth rotation, such as a hypothetical 30-hour day, which would alter gravitational effects, increasing gravity at the equator while remaining constant at the poles. The conversation suggests studying relative motions and biological impacts in this scenario, alongside mechanical and thermodynamic relationships with the Sun. Participants express gratitude for insights shared, indicating a collaborative effort to understand these complex topics. Overall, the thread highlights the interplay between historical numerology and potential future consequences of planetary changes.

I have this research about:

-why 60 as chosen as the number of seconds in a minute and of minutes in an hour;

-and the possible consequences if the Earth rotates more slowly, for example, once in 30 hours.

Please...any sort of help will do...I don't really know where to find the answers to this question and I tried to go here so...^^am counting on you guys..thanks in advance. ^_^

Ask the Babilonians, anyway: 10=2x5, whereas 60=2x2x3x5.

For the second question, I think the best way is to study relative motions in non inertial frames, the Earth (apparent forces, relative velocity of the Winds, trajectory of a falling body, pendulums, ecc...), and related biological implications.
Then you should go on to consider Earth in his relationship with Sun, referring both to mechanical problems and radiation-thermodynamical ones.
It could be interesting to consider the reasons for this slowing down.
 
hey thanks for your post Maxos, it did a lot of help. :blushing: :wink:
 
If the Earth rotates slowly then gravity at equator increases and at poles remains the same.Increase in gravity every once in 30 seconds would lead to long term affects.

thank you for appreciating
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
