Anonymous users2024-02-091.and What is the difference in pronunciation???
p ㅂ=b2.It seems that the pronunciation is different in different combinations, is there any rule?
Sometimes it depends on what the previous word is, such as = 3Hair "feather" or "v"?
Rain. 4.The word radish has two sounds, why is it only pronounced with one sound?
5.What is a genitive verb (troublesome explanation is a little more colloquial, I can't understand the language in the book) 6What is the sound of the word "rain"? BI or PI? Or is it somewhere in between?
bi 7.What is the sound of this sound?? The lips do not move, and the upper and lower teeth almost touch.
8.Is there a difference between loose and tight sounds? And is there any difference in pronunciation?
One is hard, the other is not forced, and it has to be practiced.

Anonymous users2024-02-081.Hair p, said to say hair b, but the actual pronunciation is between the two, and you will know it when you listen to it more.
2 will be a little different, but there is not as much change as "people", there is no rule, and it is still a matter of habit.
3. I pronounce it as wi but the sound is relatively light.
Does 4 mean "Ahh Hair mo
5 Don't worry so much, you will know when you learn and learn later, or take a Korean language training class.
6 is somewhere in between. Standard Korean Chinese, you can go online **, there are e-books and ***, but I personally think that if you want to say the pronunciation accurately, it is still "Korean Chinese Conversation" and "Modern Korean Chinese", but there is no online, if you buy a book, it will be taped, and the article is good, but it is more difficult than standard Korean Chinese, my suggestion is to buy both, buy the primary one first, learn standard Korean first, use Korean Chinese conversation and modern Korean Chinese as a review and consolidation, the effect is good, I learned this way, and, if you really want to learn, it is best to take the time to read a training course, First of all, the pronunciation is accurate.

Anonymous users2024-02-06The first question is to say hello, and find t according to the gravitational velocity formula 1 2* at*t=s and the second question.
To find the gliding distance, because we know the friction factor, we only need the speed in the horizontal direction according to the distance from point B to point C, and because it is just past point D, we can set the horizontal speed as VO, and the speed in the vertical direction of point B is VB
A system of column equations. BC velocity distance formula.
cc velocity distance formula.
Ask for vo

Anonymous users2024-02-02Connect cf know that the angle a + angle b + angle afc + angle bcf is equal to 360 degrees, and because af is parallel to cd, the angle afc is equal to the angle fcd, so the angle a + angle b + angle afc + angle bcf is equal to the angle a + angle b + angle c is equal to 360 according to the known conditions the angle c is equal to 120 DEGREES In the same way, connecting AD can get that the angle d is equal to 140 So we know five angles, and the last angle is equal to 720-140-140-100-120-90 = 130, i.e. angle f is equal to 130 degrees.
