The matter that mechanical waves travel through is known as ____________.
Medium
What is the product of a hydrogen fusion reaction?
Helium
This is the maximum distance the particles of a wave vibrate from resting position
What is amplitude
What happens during sublimation?
A solid gains thermal energy rapidly and turns into a gas
The total volume of an atom is localized in what part of the atom?
nucleus
Waves with shorter wavelength have more ________ than waves with longer wavelenths.
energy
It occurs when two small nuclei combine to form a larger nuclei.
Fusion
This is the bending of a wave as it passes between two substances
What is refraction
When the thermal energy of a substance INCREASES, the kinetic energy of the particles __________.
In an atom, which has the least mass? A: nucleus B: proton C: neutron D: electron
electron
A medium
Nuclear deformation leads to this when repelling electrical forces dominate over attracting nuclear forces. (Splitting nuclei)
What is fission?
What is the unit of measurement for frequency?
Hertz
How does thermal energy influence a change in state?
By adding or removing thermal energy, the kinetic energy can increase or decrease.
Describe the difference between atomic number and mass number *Multiple sentence answer*
The atomic number is the number of proton in an atom. The Mass number is the sum of the number of protons and neutrons in an atom of a particular isotope
What are the two types of mechanical waves
Transverse and Longitudinal
They cannot be separated by a chemical reaction. They must be separated by physical means. (The fuel for fission)
Uranium-235 and uranium-238
