What is the job of the magnetic field in a cyclotron?
Create a force perpendicular to the motion of the particle, which acts a centripetal force
To accelerate the particle between the dees
To apply a force parallel to the direction of motion of the particle, which acts as the centripetal force.
So the direction of the force can be alternated every half turn
There are three families of leptons;
electron, muon, and pi.
electron, muon, and tau.
electron, pi and tau.
electron, pi and neutrino.
These are the category of hadrons that contain three quarks. This distinguishes them from mesons, which contain two (1 quark and 1 antiquark).
Gluons
Electrons
Leptons
Baryons
These are light, elementary particles that are not made up of quarks.
Gluons
Electrons
Leptons
Baryon
All of the following are quarks except
strange
bottom
charmed
spark
Which row gives the correct classification of protons, electrons, and neutrinos?
A
B
C
D
What is the use of LINAC accelerator?
Deflect charged particles using electric field
Accelerate charged particles using magnetic field
Deflect charged particles using magnetic field
Accelerate charged particle using electric field
Baryons consist of (________). The example of Baryons is lambda, which is compose of?
Quarks-antiquarks particle
3 quarks
2 quarks
Leptons
Why do the tubes in a LINAC get longer throughout the accelerator?
So the particle can be accelerated
So the polarity of the supply can be switch between each tube
So the electric field can be kept constant
So the frequency of the alternating supply can be kept constant
Why do are protons in particle accelerated to close to the speed of light in particle accelerators?
To conserve momentum
To create mini black holes
So extra energy is available to create new mass
Because time slows down close to the speed of light
