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
What happens when an unstable nucleus undergoes radioactive decay
Particles or electromagnetic radiation are emitted.
What does the wavelength of an EM wave tell about its energy
As the wavelength decreases, the energy increases.
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.
Which of these is a challenge related to nuclear fusion reactions
It is technically challenging to create these reactions safely
and efficiently.
Which of the following processes does not facilitate containment
Enrichment of uranium-235 is done.
Which of these accurately describes a difference between nuclear energy and fossil fuel
Nuclear fuel has a higher energy density than fossil fuels.
Which of the following is an example of quantization
The fans sitting in the bleachers
Which equation shows how frequency is related to velocity and wavelength
Why can light be treated like a particle
Light comes in chunks of energy called photons.
What does it mean for an element to undergo transmutation
an element becomes a totally different element..
What is an effect of electrostatic forces inside the nucleus
protons and neutrons repel each other.
The protons in the nucleus repel each other...APEX
What is the fourth quantum number of the 3p1 electron in aluminum 1s22s22p63s23p1
In a nuclear fission reaction a freely moving neutron is introduced to nuclear fuel such as uranium 235 what happens next
A neutron is absorbed by an atoms nucleus
How much Cu-61 (half-life about 3 hours) would remain from a 2 mg sample after 9 hours
How much energy is released is a sample loses 0.05 kg mass through radioactive decay
A worker at a nuclear power plant has noticed that his dosimeter alarm has been activated. What might this indicate
Answer this question…
Radiation is being released from the reactor.
What is neutron moderation used to counteract against
the minimal chance that newly formed neutrons of a fission reaction are absorbed by more atoms. (apex)
Brakes are to a car as control rods are to a nuclear-fission chain reaction - true or false
Fossil fuels are running out. Solar and wind technologies are location specific and don't produce enough power to entirely replace fossil fuels. These are reasons to focus on which of the following
Rods made with non-fissioning material are inserted into the fuel tank to
slow down the chain reaction by absorbing free neutrons
