The number of times the dice have to be rolled to halve the original number of dice in the tray represents the half-life.
Figure 7 shows an eight-sided dice and a six-sided dice.

The student now used eight-sided dice to model radioactive decay. Dice that landed
on the number six were again removed from the tray.
The half-life represented by rolling eight-sided dice is likely to be different from the
half-life represented by rolling six-sided dice.

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line

You have two photos of a person walking. one shows the person at the corner of third and main streets, the other shows the person at the corner of tenth and main streets. there are lampposts at every corner in this town, and the first picture shows it to be 10: 32: 00 exactly. the second picture shows it to be 10: 49: 30. you know three facts: (1) all of the clocks are synchronized; (2) there are exactly 12 equal-sized blocks per kilometer in this town; and (3) the streets that cross main in this area are numbered consecutively, with no interruptions. what is the person’s average speed in kilometers per hour?
