PLEASE HELP ASAP 25 POINTS GOOD ANSWERS ONLY! bob has 8 pieces of square index cards that each measures 8 inches per side. Using a pair of

scissors, he cuts each piece in half (so the resulting size is 8” x 4”) and then places all the

resulting card pieces in a new stack. If he repeats this procedure 4 more times, how many

pieces of card stock will he have and what will be the measure of each piece? (Note: All

cuts will be made along the longer edge of the piece if the piece of index card is not square.)

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
