Since density is mass per unit volume, the density is the same.

When a marble hits a row of marbles why does only one marble fly of?
Only one marble comes off because the energy is transferred through the line of marbles and is expelled at the end driving the last marble to release
If electrons flow slowly why do lights turn on so fast?
The individual electrons move slowly; the current moves quickly. Compare this to a water wave: the wave advances, but the individual water particles go back to their place. You should actually observe a water wave to confirm this. Check objects floating on the water. The wave is NOT a current of water. You can also compare this to the following neat experiment with marbles: Put three (or more) marbles in a row, touching each other. Have one more marble bump into the row. The marble at the other end goes off - the other marbles stay in their place! The energy has been transferred from one marble to the next, but each of them (except the last one) stays in its place!
How does the density of a spherical gas cloud of 105 solar masses and 10 parsecs in radius compare to the density of water?
The density of water, at one atmospheric pressure, is approx 1000 kg/m3. The density of the gas cloud is 1.89*10-22 kg/m3 which means the cloud is approx 1.9*10-25 times (190 octillionths) as dense.
Do marbles go further down a hill if the hill is steeper?
Yes, sometimes and no sometimes. In the case of rotating objects the more import value is moment of inertia. An object with a higher moment of inertia will accelerate slower (roll slower comparatively for any given time after release) down an inclined plane. In the case where the marbles are of equal diameter and uniform (although different if one is to have more mass) density the heavier marble will roll slower down a slope. For those interested in a short description followed by plenty of calculus. http://en.wikipedia.org/wiki/Moment_of_inertia
Compare general properties of matter from specific properties of matter?
A 'specific' property is a property that depends on or is calculated based on another measurable property. You give an example of density; density is considered 'specific' because it can be calculated from volume and mass. Some other good examples are: - specific gravity - the density of a material relative to the density of water (volume and mass of the object, known density of water) WHILE There are four different properties of matter. They are weight, volume, mass, and density. The most important one is mass. Mass is the amount of matter in an object and it never changes unless matter is taken out of the object.olume is another general property of matter. Density is very important because it enables you to compare different objects.weight is the force on the object due to gravity.
If the density of one marble is 2.5 gcm3 what is the density of four marbles?
Density is mass per unit volume. More marbles is more mass, but will be more volume as well. If the marbles are all the same, any number of them will have the same density, which is 2.5 grams/cm3. This is a "thinking" problem rather than a "calculation" problem.

A bag contains 6 purple marbles and 7 white marbles Two marbles are drawn at random One marble is drawn and not replaced Then a second marble is drawn What is the probability that the first marble?
There are 13 marbles in total. The order is specified.P(1st is white and the 2ndis purple) = (7/13)(6/12) = (7/13)(1/2) = 7/26.
Explain how four red marbles can make up one third of a group of marbles and three blue marbles make one fourth of the same group?
minus one red marble plus one blue marble
A bag contains 2 red marbles 3 blue marbles and 5 green marbles. if one marble is drawn from the bag what is the chance that the marble willbe red?
It is 2/10.
12 red marbles and 15 marbles are blue. if one marble is drawn from the bag What is the probabilitythe marble is not be red?
15/27. Simply take the probability of drawing a blue marble.
How do you make a marble sorter hopper release one marble at a time?
Carefully assemble the box of marbles to the box of marbles to the box of human fecies
Jan has 4 blues marbles 3 red marbles 2 yellow marbles in a bag Jan will randomly pick one marble from the bag What is the probability that the marble will be yellow?
2/9
If A bag contains 3 red marbles and 5 purple marbles One marble is drawn at random and not replaced Then a second marble is drawn at random What is the probability that the first marble is purple and?
3/5
A bag contains 6 red marbles 7 blue marbles and 6 green marbles If one marble is randomly picked from the bag what is the probability that this is a blue marble?
There would be a 7/19 or 36.84% chance of drawing a blue marble from the bag.
A bag contains 3 green marbles 5 blue marbles and 2 yellow marbles one marble is drawn from the bag what is the probabitity that a blue marble is chosen?
the probability that a blue one is chosen is 5/10 which is equal to 1/2
A bag contains 4 red marbles and 3 black marbles You dram one marble look at it and put it back Then you draw one marble again What are your chances of getting 2 black marbles?
3/7*3/7= 9/49
