Kwarki

Question 1

What are quarks?

Answer 1

Quarks are fundamental particles and a basic constituent of matter.

Question 2

How many types of quarks are there?

Answer 2

There are six types of quarks, known as ‘flavors’: up, down, charm, strange, top, and bottom.

Question 3

True or False: Quarks can exist freely in nature.

Answer 3

False. Quarks are never found in isolation; they combine to form hadrons.

Answer 8

C) Left

Question 9

What is the primary interaction that quarks participate in?

Answer 9

Quarks primarily participate in the strong interaction.

Question 10

True or False: Quarks have a property called color charge.

Answer 10

True.

Question 11

What is the color charge of quarks?

Answer 11

Question 12

Fill in the blank: The strong force is mediated by _____ particles.

Answer 12

gluons

Question 13

What are baryons?

Answer 13

Baryons are particles made up of three quarks.

Question 14

Question 16

What is the role of the Higgs boson in relation to quarks?

Answer 16

The Higgs boson gives mass to quarks through the Higgs mechanism.

Question 17

True or False: Quarks have intrinsic spin.

Answer 17

True.

Question 18

Fill in the blank: Quarks combine to form protons and neutrons through _____ interactions.

Answer 19

strong

Question 20

What is confinement in the context of quarks?

Answer 20

Confinement is the phenomenon where quarks cannot be isolated and must exist within hadrons.

Question 21

Multiple Choice: Which quark is the lightest? A) Up B) Down C) Strange D) Bottom

Answer 21

A) Up

Question 22

What is the mass range of quarks?

Answer 22

Quark masses vary widely, from a few MeV/c² for the up and down quarks to about 173 GeV/c² for the top quark.

Question 23

True or False: Quarks and leptons are both considered fundamental particles.

Answer 23

True.
