Answer:

They’re made up of more than one substance.

They have the same or similar properties as the materials used to make them.

Explanation:

They’re made up of more than one substance. True.

For example concrete is made up of a loose stones embedded in a matrix of cement.

They have the same or similar properties as the materials used to make them.True.

Concrete is robust and  can withstand high compression forces.

They’re always made of metal. False.

Concrete is not made up of a metal.

They’re readily available in nature. False.

Concrete is a man made substance. All composite materials are made by engineers they do not occur naturally in nature.

The energy of a photon is 4.23 x 10-17 J. What is the wavelength of the radiation?
Ludmilka [50]

The wavelength of the radiation is 4.7 x 10⁻⁹ m

What is the Einstein's Formula for Energy?

The energy

E is given, from Einstein's formula, as:

E=h⋅ν

Where:

h=6.63×10⁻³⁴Js is Planck's constant;

ν is the frequency.

You can relate frequency and wavelength

λ through the speed of light c as:

c=λ⋅ν

So finally you get:

E=hc/λ

It is given in the question

The energy of a photon is 4.23 x 10⁻¹⁷ J.

Wavelength = ?

λ = hc/E

λ = 6.63×10⁻³⁴x 3 x 10⁸ /  4.23 x 10⁻¹⁷

λ = 4.7 x 10⁻⁹ m

Therefore the wavelength of the radiation is 4.7 x 10⁻⁹ m .

An ideal gas is stored in a container at constant volume. If the temperature (T) were increased to 3T, what would be the change
Olin [163]
According to Gayle Lusac's law, pressure is proportional to absolute temperature of a gas. Thus:
P/T = constant

So if the temperature becomes 3T, the pressure would increase to 3P
