AI Thread Summary
Fluorine is added to tap water to help prevent tooth decay, as it reacts with water to form hydrofluoric acid. The moon Io, one of Jupiter's moons, is believed to have its distinctive color due to the presence of sulfur. Before silicon became the standard, germanium was used to make semiconductor components. Triton, a moon of Neptune, is located in orbit around the planet. The discussion highlights the importance of community support in problem-solving.

1) why is the element fluorine added to tap water?
2) what element is believed to give lo.a moon of Jupiter its distinctive colour
4)what element was used to make semiconductor components before being replacedby silicon
5)where is triton found, please elaborate on it

thanks kaluence

1) As F is very very reactive , it is kept in water via following reaction:

F(2) +H(2)O -----> HF + O(2)

Orbiting neptune. :wink:

Seriously, though, you should show some attempt to do the problem before asking us.
 
sorry, cause i just realize 5-6mins before i realize i had to answer this question,but thanks i really love the comunity her.. you guys are always so frenly and nice.. haha btw i found the answers already..realise deadline was next week not this week :smile:
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging 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...
