    How to ask some one in Japanese where he lives?

    doko ni asundeimasu ka? that translates ‘exactly as’ where do you live? How does it reads phonetically? You need to know the exact way a hiragana is defined and mapped into a specific form of Roman alphabet making, called Romaji or Hepburn transliteration rule — as far as I know its only the Japanese system…

  • A Question a Day (series) Q3

    The equation v = a*del_t is sometimes used to find velocity when acceleration and time are known. Another form of this equation is v = v_0 + a*del_t. In this second form of the equation, the function of the term v_0 is to: A. indicate that the equation is valid only for an object that…
