    the angle left behind after you do 180 - 120 = 60. Now just resolve the 10 N to get the horizontal component, which is 10cos(60) = 5 The 5N and the 10N are in opposite directions so subtract them you get 5 N, and so the answer is A. Here is a picture...

    well i dunno but i did it in quite an easy way.....you know that when 3 forces are acting their lines of action must pass through the same point. If you extend them all till they meet, and compare the size you will se W is the smallest magnitude then H and then T. so the answer is C

    7 - if you resolve the vector you will see that the horizontal component is ucosα while there are two vertical components...taking in mind that they are acting in the opposite directions. First is the result of resolving the vector on the y axis : usinα and the second is the acceleration...

    the pressure can be 0.9Po on the top, without the water spurting out...it just means that the straw is really long! so you mean to say the answer is supposed to be A...

    Saad (سعد) Jaf this question...argh! the question says the child is capable of reducing the pressure at the top by 10% so the pressure at the top is now 0.9Po and it gives you the right answer when you substitute it into P=pgh! but why does the examiner report say so! is it cuz there asking...

    was quite easy, nothing too hard came, and was perfect for 1 hour!...im afraid the grade threshold will be quite high though...
