Wouldn't that just introduce another unknown variable which would require us to have 2 equations in order to solve. I thought this route already but didn't bother going this way since I don't know the ratio, and hence the value of k.
Relative to the origin O, the position vectors of two points A and B are (1,4) and (7,1) respectively. Give that the point P (t,t+1) is on AB find
1) AP and BP in terms of t
2) Find the value of t and hence the ratio AP:PBSolution:
1) AP= (-i - 4 j) + ti + (t+1)J = (t-1)i + (t-3)j
BP=...
I'm assuming a and b are two non-parallel arbitrary vectors, as the question never specified what their relationship was. The diagram was used to visualize and help solve the second part of the question where they stated that if the parallelogram OPQR was a square, show by using two scalar...
Homework Statement
The point P and Q have postion vectors a + b, and 3a - 2b respectively, relative to the origin O.Given that OPQR is a parallelogram express the vector PQ and PR in terms of a and b. By evaluating two scalar products show that if OPQR is a square then |a |2 = 2 |b |2

Calculate the standard enthalpy of ethyne
C2H2 + 2H2 -------> C2H6
Assume the following mean bond energies
C\equivC = 813 KJ mole-1
C - C = 364 KJ mole-1
C - H = 413 KJ mole -1
H - H = 436 KJ mole -1
Attempted Solution:
Bonds broken
1 C\equivC = 813 KJ mole-1 ( 813 KJ...
Interesting what about if the moon was destroyed by weapons from earth. The gravitational biding energy of the moon is 1.245×10^29. The largest nuclear bomb detonated was Tsar bomb, which only had around 10^17 joules. So You would need roughly 1,000,000,000,000 of them.
Say if we had the...
