When a marble is dropped in a bucket of water it sinks to the bottom. Is it because the marble weighs more than an equivalent volume of the water or the marble has greater mass volume than the water O?
All of the above? You can say the same thing in many ways. All of the following are different ways of saying the same thing, and all are correct: The marble sinks because the marble weighs more that an equivalent volume of water. The marble sinks because its density is greater than the density of water. The marble sinks because it has a greater mass than than same volume of water (and there is gravity/acceleration).
Is the inertia of a marble greater than a basketball?
Indeed.
What is the least number of turns needed to be certain that you draw a blue marble from 4 red 6 white and 8 blue?
You have to draw out all the red and white marbles than a blue so 4+6+1=11The answer is 11 turns.
Would the total momentum still be zero if one marble had greater mass than the other marble?
If the momentum started as zero, yes, it would.
What is the green ball?
Before colour TV balls used in statistics were coloured black and white. Statistical questions were posed asking, say, the probability of selecting a white ball from a mixture of black and white balls hidden in a bag (sometimes white and black balls). A practical set up that, over a large number of tries, would show that the maths being examined was (statistically) good. Since colour TV there has been a preponderance of the use of coloured balls in the experiments and, often, one of the colours used is green. Also, using colour allows more than two different things to be the subject of statistical experiment. Of course colour TVs had nothing to do with this but the rest is true - honest. Beano GB
