Could someone explain the relation of colors and waves to me please? And could you tell me a bunch of things about colors and wa
skelet666 [1.2K]
Color depends on the wave length produced, for example if the wave length is shorter then it would produce violet and when it continues to get higher it produces other colors. from low to high it goes, violet, indigo, blue, green, yellow, orange, red. those are also only in the visible light spectrum whereas there are plenty of other wave we cannot see with the human eye.

A titanium cube contains 2.86×10^23 atoms. What is the edge length of the cube? The density of titanium is 4.50 g/cm^3. (The vol
Arada [10]

Answer: 1.72cm

Explanation:

First let us calculate the mass of titanium that contain 2.86×10^23 atoms..

1mole of a substance contains 6.02x10^23 atoms as we have come to understand from Avogadro's hypothesis. Therefore, 1mole of titanium also contains 6.02x10^23 atoms.

1mole of titanium = 48g

1mole (i.e 48g) of titanium contains 6.02x10^23 atoms,

Therefore Xg of titanium will contain 2.86×10^23 atoms i.e

Xg of titanium = (48x2.86×10^23)/6.02x10^23 = 22.8g

Next, we must find the volume of titanium

Density of titanium = 4.5g/cm^3

Mass of titanium = 22.8g

Volume =?

Density = Mass /volume

Volume = Mass /Density

Volume = 22.8/4.5

Volume = 5.07cm^3

Now we can find the edge length:

Volume = 5.07cm^3

Length =?

V = L^3

L = cube root (V)

L = cube root (5.07)

L = 1.72cm

A scientist measures the weights of two different animals. One is 250 grams. The other is 330 grams. In milligrams, what is the
Stolb23 [73]
The way you would answer this is convert the grams to milligrams (g to mg) that would give you 330,000mg and 250,000mg then subtract them

Remember 1g = 1000mg
