Since density is mass per unit volume, the density is the same.
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
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!
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.
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
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.
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.
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.
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
minus one red marble plus one blue marble
It is 2/10.
15/27. Simply take the probability of drawing a blue marble.
Carefully assemble the box of marbles to the box of marbles to the box of human fecies
2/9
3/5
There would be a 7/19 or 36.84% chance of drawing a blue marble from the bag.
the probability that a blue one is chosen is 5/10 which is equal to 1/2
3/7*3/7= 9/49
