For electromagnetic waves frequency X wavelength = speed of light

                                                f * 2.2 x 10^-11  = 3 x 10^8  m/s

                                         f = 3 x 10^8 / 2.2 x 10^-11

                                            = 1.36 x 10 ^19

The mass percent of gold in the piece is 79.08%

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

Thus,

Mass = density × volume

Mass = density × volume

Mass of gold = 19.3 × V

Mass of gold = 19.3V

Mass = density × volume

Mass of silver = 10.5 × (1.25 - V)

Mass of silver = 13.125 - 10.5V

Mass of piece = mass of gold + mass of silver

20.5 = 19.3V + 13.125 - 10.5V

Collect like terms

19.3V - 10.5V = 20.5 - 13.125

8.8V = 7.375

Divide both sides by 8.8

V = 7.375 / 8.8

Volume of gold = 0.84 cm³

Thus,

Mass of gold = 19.3V

Mass of gold = 19.3 × 0.84

Mass of gold = 16.212 g

Mass percent of gold = (mass of gold / mass of piece) × 100

Mass percent of gold = (16.212 / 20.5) × 100

Mass percent of gold = 79.08%

A block has a density of 1.73 g/mL has a density of  1.73 * 10⁶ mg/L.

The density of a substance is the ratio of the mass of a a given volume of a substance and the volume of that substance.

Mathematically, the density of a substance is given by the formula shown below:

Depending on the units in which the mass and volume of the substance is given, the unit of density can be given as follows:

kilogram per cubic meter; kg/m³

gram per cubic centimeter; g/cm³

gram per liter; g/L

milligram per liter; mg/L

The given block  has a density of 1.73 g/mL.

To convert from gram to mg, we multiply by 1000

1.73 g = 1.73 * 1000 = 1730 mg

to convert from mL to L, we divide by 1000

1 mL = 0.001 L

Density of the block in mg/L = 1730 mg/ 0.001 L

The key difference between free radical and ion is that the free radicals have one or more unpaired electron, but ions have paired electrons.

What is the Paired and Unpaired Electrons?

Unpaired electrons are the ones that appear in an orbital alone, while paired electrons are the ones that appear in an orbital as pairs in an atom. So, in the orbital, paired electrons always appear as two electrons, whereas unpaired electrons always appear as a single electron. The main distinction between paired and unpaired electrons is this. Additionally, whereas unpaired electrons result in paramagnetism or ferromagnetism in atoms, paired electrons cause diamagnetism in atoms.

A change in the orbital motion of electrons caused by an applied magnetic field induces diamagnetism, a very weak form of magnetism. This magnetism is transient and only endures when an outside field is present.

If you progress from the equator to a location within the mid-latitudes, the wintertime average temperature will decrease, and thus the temperature range will increases.

As latitude increases, the temperature falls, and therefore the other way around. Generally, round the world, it gets warmer towards the equator and cooler towards the poles.

However, other factors could influence the temperature in several locations like altitude, precipitation, and ocean currents

Why is it called latitude?

On a map where north is up, latitudes run laterally (left to right). they're named after the angle created by a line connecting the latitude and the center of the Earth, and therefore the line connecting the equator and the center of the Earth.

There are actually two models of electromagnetic radiation. One is the wave model, of course, and the other is the particle model, which postulates that radiation is made up of a stream of discretely sized particles called light quanta.

Different ideas about the energy connected to radiation are produced by the two theories.

The energy is stored in the EM fields that are moving through a region when the radiation is thought of in the wave model as an EM wave.

The wave oscillations in the wave model hold the energy.

Conceptually, the particle model differs slightly. Since each discrete particle in radiation has a specific amount of energy, the total energy of the radiant beam is determined by the number of discrete particles that make up the radiation.
