Examples are: density, thermal conductivity, refractive index, viscosity.
Properties of radio wave ar: sound, uses of antenna, hz.
* Ar = lw * Ar = (4cm)(10cm) * Ar = 40cm2

The ions or atoms with paramagnetic properties are: S and Zn. Ar, S2-, F-, do not exhibit paramagnetic properties because they have all of their electrons paired up in their orbitals. Zn has incompletely filled d-orbitals, making it paramagnetic.
A square has 4 congruent sides and 4 congruent angles
The answer depends on what a "4 mile meter" is!

I'll try to answer the question, "If the 5th term of a geometric progression is 2, then the product of its FIRST 9 terms is --?" Given the first term is A and the ratio is r, then the progression starts out... A, Ar, Ar^2, Ar^3, Ar^4, ... So the 5th term is Ar^4, which equals 2. The series continues... Ar^5, Ar^6, Ar^7, Ar^8, ... Ar^8 is the 9th term. The product P of all 9 terms is therefore: P = A * Ar * Ar^2 *...*Ar^8 Collect all the A's P = (A^9)*(1 * r * r^2 ...* r^8) P = A^9 * r^(0+1+2+...+8) There's a formula for the sum of the first n integers (n/2)(n+1), or if you don't know just add it up. 1+2+...+8 = 36 Therefore P = A^9 * r^36 Since 36 is a multiple of 9, you can simplify: P = (Ar^4)^9 Still with me? Remember that Ar^4=2 (a given fact). So finally P = 2^9 = 512. Cute problem.
Neon and argon have very similar chemical properties; mainly, they do not naturally react with any other element. This is why they are placed in the same group (#18) of the periodic table.
