  1. According to the principle of utility, we have to maximum the benefit of the greatest number of people. However, imagine a situation like that, a traditional city has a very special ritual that they need to leave a boy in a place with enough water and food for sometimes. No one is allowed to go in the place therefore the boy is completely isolated in the room. But , that will bring prosperity and wealth to the city. Now a boy is kept in the room. After a year the boy is dead, the mayor has found a qualified boy who is you to stay in the room. They then kidnap you to the room but luckily you
  2. Does anyone know the reason that the boiling point of oxygen is lower than that of fluorine ?_?
  3. Electric field lines kinda confuse me!!! Teacher told me that inside a conductor, the electric field is zero. But i wonder why? And also if it is zero inside the conductor then why are there still electric field lines outside a conductor?
  4. Hey guys. I would like to ask according to the conservation of energy, energy can't be created or destroyed. Then, where is energy come from??
  5. Does it imply that the randomness or i should say probability is eliminated after we finish flipping the coins?
  6. Hey guys. As we all know that if we flip a coin, the possibility/probability of getting a tail or head is 50%. Suppose a man is flipping the coin and record the results, say , 10 times. The probability of getting all heads or tails is 0.5^10 = 9.765625x10^-4 which means that the probability is extremely small. Now, if the man has a result of 10 heads. The experimental probability of getting heads = 10/10 = 1 In that case, is there still any probability existing while we are flipping coins???
  7. I guess you can just simply use the fact that 1-P(at most 1) = P(at least 2) to solve the problem...
  8. i guess something exists from nothing is more related to physics...
  9. But ask yourself 3÷(1+2) = ? If we use the pattern mentioned above , it will be just like 3÷1x(1+2) = 3 x 3 = 9 which is completely nonsense
  10. How can you prove that 2(9+3) = (2(9+3))? I mean the bracket( 2(9+3) ) is added yourself. My primary teacher told me that brackets are at the first priority to solve and there is no rule of precedence of multiplication and division. That means after solving the brackets, we have 48 ÷ 2(9+3) =48 ÷ 2 x 12 =288 and that's also quite reasonable , i guess. Well but my first answer is 2. Truely , i thought it is 2 but the ''288 guys'' still have their own reasons which can't be neglected.
  11. well I guess it should be 2 at first but later i asked my classmates and they had different answers Some are 2 and some are 288 That's why i am confused
  12. Well...Thx for ur help I've also got a question which i guess almost everyone knows lol is that 48÷2(9+3) = ?
  13. So that means i need to treat 2y as 1 term?
  14. Want to ask a moronic question, can anyone answer me!! 48÷2y =24y or 24/y?
  15. Suppose now we have two acids A. 10 cm3 of 1M sulphuric acid B. 10 cm3 of 1M hydrochloric acid I just want to ask how should I calculate in order to know which acid has a higher concentration of H+
