I think that the second tippe top will spin on its stem first, and the first tippe top will stop spinning first due to its greater mass and lower angular velocity. Here are my ideas:
They are given the same initial energy. By the conservation of energy principle, an object with greater mass...
We see under trees circular light that goes from sun through the leaves gaps. Why does it create a circular shape and not other shapes? why does this diffraction phenomenon create it in circular patterns?
Sure imagine that the Pita is like U (has a narrow part and open part) and it is put on a line (that is the heat energy source - plate). Should it be more efficient to put it in U for or opposite?
What is the optimal and efficient way to warm a concave body on a plain source of heat (such as heating concave pita bread) on its peak top or opposite (on the larger surface with gap)? Imagine you have a body in U shape. Is the best way to warm it with the U position or opposite?
