    Heat Ocean
AI Thread Summary
The discussion centers on whether the last sip of tea thrown by Queen Elizabeth over Queen Mary's rail would warm the ocean. Participants debate the impact of the tea's heat, considering the vastness of the ocean and the cooling effect of the air it passes through. While some argue that the tea's warmth could raise the ocean temperature slightly if it is warmer than the surrounding water, others emphasize that the heat would dissipate quickly. Factors such as seasonal air temperatures and the cooling effect of friction are also mentioned. Ultimately, the consensus is that the effect is negligible and context-dependent.

True or False: When Queen Elizabeth throws the last sip of tea over Queen Mary's rail the ocean gets a little warmer?

I want to say it is false because of how large the ocean is, but he heat of the tea has to go somewhere right? Which makes me want to say true. :confused:

On normal case,it would...But let's not forget the air the tea has to travel through before coming into contact with the water...Generally,the air is cooler during the winter & a warmer during the summer...So there a lot of side factors that would normally have to be taken into account...

Daniel.

P.S.The answer is YES & NO.BUT IT ALL DEPENDS... :-p
 
Hey thanks. So if the temp of the tea is warmer than the temp of the ocean when it goes into the ocean the answer is true.
 
That's right...But in general,the liquid loses heat through the friction with cooler air...

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...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
