Quarks

Question 1

What are quarks?

Answer 1

They are the building blocks for hydrons

Question 2

what are the two type of quarks you need to make a proton and neutrons?

Answer 2

up and down quark

Question 3

What is the strange quark used for

Answer 3

lets you make particles with a property called strangeness

Question 4

When is strangeness conserved?

Answer 4

Only some of the time, in the strong interaction

Question 5

What is an example of a strange particle?

Answer 5

Kaon, these are created via strong interaction but decay in the weak interaction

Question 6

How are strange particles produced?

Answer 6

They are produced in pairs, one has a strangeness of +1 and one has a strangeness of -1 therefor the overall strangeness is 0 so its conserved.

Question 7

How many quarks are baryons made up of?

Answer 7

3 quarks

Question 8

What is the quark structure for a proton?

Answer 8

uud

Question 9

what is the quark structure for a neutron?

Answer 9

udd

Question 10

What are pions made up off?

Answer 10

up, down, anti-up and anti-down particles

Question 11

What are four properties which are conserved in particle interaction?

Answer 11

charge, baryon number, strangeness, conservation of lepton number

Question 12

When a weak interaction occurs what happens to the quark structure?

Answer 12

The quark structure changes for instance if a neutron decays into a proton the structure will go from udd to uud
