Ok let me help you with this:
<span>
!n case a) Line both up head-to-tail in a straight line... that's the only way to get a sum 2F. In case b) sqrt(2) is the length of the hypotenuse in a 45 degree triangle, so the vectors must be at 90 degrees to each other
in the case of c) lined up head to tail, the only way to get 0 is if they point in opposite direction</span>
<span>Which of the following has the greatest entropy? (Assume the same number of particles in each sample.)
An Ice Cube i think</span>
5
If you go over 2 on the time bar, and you look for the black dot above the 2 on the bottom time bar, it would go up to 5.
