For the last one I got like 0.344 - I don't think you can just say some arrangements yield more points for the home team, because the arrangements all have different probs, for example wwdd has a different prob than wwld. I wrote down the different selectinos, calculated the prob and multiplied...

The right hand palm rule for induction means you point your palm in the direction OPPOSING the motion. Thus your palm points towards you.

For GPE I got the same as KLAW, but I wrote the answer in joules: 750, 000 J

This is what I did: Gradient = Mass\current Force\Current = 9.8 * gradient invert that then substitute in values

Question 9: google 'Faraday disk dynamo' you will get contradictory results! I think the Nasa site says B, one of the physics sites says C. Otherwise my answers are exactly the same as pianpudodoel's.

Father and Child was a good idea, but 'Alter Ego'? I hope my linking was watertight there.

An example of conflict is 113 trichloro 133 trifluoro propane. This could also be 133 trichloro 113 trifluoro propane. According To Conquering Chemistry the second one is correct. Spotlight is unclear on this, although I think in some questions they seem to suggest the first name. Other books...

Question 2: I believe this is just basic triangular equality. Let B represent |z1|, C represent |z1+z2| and A represent the origin. Now, Length BC is given by |z2|. So, applying the triangular inequality, |z1+z2|+|z2|>|z1|, so |z1+z2|>|z1|-|z2| (sum of two sides of a triangle is greater than...

lol...and use a ruler too... Thanks for that. I was having a mental block on that one....

Another Circle Geometry Problem: Draw a tangent to a circle, meeting it at N. Draw two chords PN and QN. Draw a line parallel to the tangent such that it meets PN at K and QN at L. Let the perpendicular bisectors of PK and QL meet at a point W. Show that as the line KL varies, the locus of W...

Apparently the first thing to do is to find which way yields the lowest set of numbers. In this case I think both directions are the same. Then, if both directions are the same, you give the lowest number to the first named halogen, which is bromine anyway. I thought I read before somewhere it...

Perhaps a definition of what a simulataneuos event is is in order here. Suppose in Ennaybur's example one star explodes at A, and another explodes at B. If an observer standing at the midpoint of A and B observes both events to happen at the same time (relative to them) then the observer...
