    Question about the impulse....if there are two objects with the same mass and volume and moving with the same speed, one is hard and one is soft...what is the difference between the impulse of each?

    well 3 b is : 1) the sum of the forces in any direction must be zero 2) the sum of the moments of the force about a point must be zero and if you mean 3 c ii.... 1) quite simple... M abut a point = force x perpendicular distance = (30/100) x 150 = 45 Nm 2) it must be equal to the moments so it...

    first here is how you convert the degrees and radians... radians to degrees : multiply by 180/π degrees to radians: multiply by π/180 Phase difference is simply is the fraction of the cycle (the angle) by which one wave moves behind the other. you can calculate is by using this equation: (with...

    i checked up the syllabus and it mentions all the normal things in this chapter but the last line says...''use the knowledge gained in this section in new situations or to solve related problems'' so i guess the electrocardiogram and the pressure graphs come in the related stuff. no harm in...

    there the little scale given on the side is the same magnification as the photograph, so you use it to calculate the mag cuz its the same for the same and the photograph...the length of the mini scale is 1.5 cm -> 0.015 m -> 15 000 micrometers. now just divide the 15000 by 0.5 micro meters the...

    Chemistry 21

    hmmm....thats probably true bout the Kp, but surely for the change in temperature the Kc value changes, and this is becuz the eq. yeild chnages. oh forget it brotha...wait till the mark schemes come out XD

    Chemistry 21

    what i meant to say was...that Kp is calculated only when the reaction is equilibrium. When you change any of the factors the equilibrium doesnt remain anymore so how will you calculate Kp. your not seeing the affect on Kp but on the equilibrium :/ hope so atleast.

    Chemistry 21

    if thats true....thats a whole lot ov marks man. -_-
  15. G

    Chemistry 21

    hmm, true. but ull calculate the Kp when the reaction is in equilibrium. when you change the temp or pressure the equilibrium shifts...right? at this point you cant even calculate the Kp. though the change is reversed later on. anyhoo, smart thinking. to all those who thought so :p

    true...but in teleophase the chromosomes usually appear decondensed (or not aligned), and a nuclear envelope reforms....in this picture the chromosomes are still sort of aligned and no nuclear envelope has yet formed, which means it is anaphase..it could also be early telophase, and the mark...
