What is the total kinetic energy of the atoms and molecules in an object called

Temperature is the measure of average kinetic energy of all the atoms and molecules in an object

If a wave is moving at a constant speed and the wavelength is doubled what will happen to the frequency

IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).

What is the nuclear decay equation for an example of alpha decay

The equation for the alpha decay of 239Pu is: 94239Pu --> 92235U + 24He

where 24He represents the alpha particle, which is a Helium nucleus.

How do electrostatic forces affect the electrons in an atom

The electrons are attracted to the protons.

What is important in order for a radioisotope to provide accurate dating results

The half-life should be similar to the age of the object.

What information does the first quantum number of an electron give

The energy level the electron is in

Which of the following processes does not facilitate containment

Enrichment of uranium-235 is done.

Which of the following is an example of nuclear fission

A large radioactive atom breaks into smaller atoms, producing nuclear energy.

Which of the following is an example of quantization

The fans sitting in the bleachers

Which of these describes a similarity between nuclear energy and fossil fuel

As both fuels undergo reactions, heat is released, which is used to do work.

Which of these is a reason why nuclear power is important

Fossil fuels will run out soon.

What is the fourth quantum number of the 3p1 electron in aluminum 1s22s22p63s23p1

ms = +1/2
