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 the biggest problem with radioactive waste
It has a very long half-life. Disposal of radioactive waste is
the biggest problem. Proper disposal is essential to ensure
protection of the health and safety of the public and quality of
the environment including air, soil, and water supplies.
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 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.
When a nucleus absorbs a neutron and then breaks apart there are many products of the reaction Which of these is not a product of a nuclear fission reaction
Which of these is a reason why nuclear power is important
Fossil fuels will run out soon.
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 represents a alpha particle
During an earthquake the cooling system of a nuclear reaction can be compromised increasing the threat of what
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.
In neutron moderation neutrons are slowed down so that
they will more likely be absorbed by more atoms in
uranium-235
Brakes are to a car as control rods are to a nuclear-fission chain reaction - true or false
Rods made with non-fissioning material are inserted into the fuel tank to
slow down the chain reaction by absorbing free neutrons
