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 of language of hiragana and katakana and associated rules of the kanji reading, which employs the Hepburn system. So Romaji is an exactly matching mapping, of say hiragana alphabet.
In that system of phonetic definitions do is to be read as do in say Dorothy, but the D is not said as D in David, but as in ‘the’, if ‘the’ were to be read as ‘tho’. In a round about way, we find the phonetic. do is to be read as, ‘do’ in although.
do = though, phonetically. More…
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 starts at rest.
B. determine the time at which
velocity is equal to zero.
1. A ball is thrown with an initial velocity of 20 m/s at an angle of 30°
above the horizontal. What is the instantaneous vertical velocity of
the ball when it is 5.1 m above the release point? (g = 9.8 m/s^2)
A. 0.2 m/s
B. 6.6 m/s
C. 10 m/s
D. 17 m/s More…
