    Maths P3 !!!Need help in finding perpendicular distance between point and line!!!

    One of the questions is q2 from the p3 book. find the distance of (1,0,0) from r=t(12i-3j-4k) my soln: a=i unit vector in direction r, n=(12/13)i-(3/13)j-(4/13)k a.n=12/13 |a|=1 so, shortest distance=sqrt(1-(12/13)^2)=5/13 answer on the back of the book is (1/13)*sqrt(69)

    Phys p12 and Chem p12- 9th and 10th June,2015 Tips!

    Cyclopropane has molecular formula C3H6. So, making 1 mole requires 3 moles of C atom and 6 moles of hydrogen atom or 3 moles of hydrogen gas. So we can make an equation, 3*dH(C{graphite})+3*dH(H2)-3*dH(C-C)-6*dH(C-H)=53.5 so, 3*dH(C-C)=3*dH(C{graphite})+3*dH(H2)-6*dH(C-H)-53.5...

    I'm a bit clueless about the first one. No idea what a steel post is and can't understand what do they mean by the copper wire. All I'm sure of is that the answer is not C or D. By the way which year is it from? As for the second one, the sum of total momentum=2m*u-m*u=mu in A, total momentum=...

    How was chem p34

    For the titration I got 22.68(average), but what I am worried about is the enthalpy. My final answer was 2.0KJmol^-1, but most online resources put it at X10 that:censored:
