What is the mass of a sample aerogel?
That's going to depend on the size of the sample you have. A larger sample will have more mass than a smaller sample, much like virtually every other known substance. Aerogel is a synthetic porous material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and thermal conductivity. It is nicknamed frozen smoke, solid smoke, solid air or blue smoke owing to its translucent nature and the way light scatters in the material; however, it feels like expanded polystyrene (styrofoam) to the touch. Various samples of aerogel may have densities anywhere between 1 mg/cm3 (less dense than air) to 2 mg/cm3 .
A magnetic material has a relative permeability of 10000 what does this mean?
The relative permeability of 10,000 means that the material can support a magnetic field 10,000 times more dense than than a magnetic field in free space.
Can you fold a circle into halves more than 15 times?
No, you cannot fold a circle into halves more than 15 times. Theoretically, each fold doubles the number of sections, but practical limitations arise due to the increasing thickness and reduced size of the folded material. In reality, after about 7 or 8 folds, the material becomes too thick and small to fold effectively. Thus, achieving more than 15 folds is not feasible.
What does times more mean?
Three times more is NOT defined as "triple". Rather it is "triple more". Three times MORE than 4 is NOT 12. Three times AS MUCH as 4 is 12. Three times MORE than 4 is 12 more than 4, which is 16.
How many times more is hundred thousands then ten thousands?
10 times more. A hundred of anything is 10 times more than 10 of the same thing.
