Question 1

In E=mc² -c stands for _____. A) speed of sound B) energy construction C) speed of light D) energy of fusion

Accepted Answer

In the equation E=mc^2, "c" stands for the speed of light in a vacuum, which is approximately 299,792,458 meters per second.

Question 2

The force that holds the nucleus of the atom together is called the _____.&#10;A) weak force&#10;B) nuclear force&#10;C) neutron force&#10;D) E-M force

Accepted Answer

The nuclear force, also known as the strong force or strong nuclear force, is responsible for holding the protons and neutrons together within the nucleus of an atom.

Question 3

This is an almost massless particle that is produced in fusion:&#10;A) proton&#10;B) electron&#10;C) neutron&#10;D) neutrino

Accepted Answer

Neutrinos are almost massless particles produced in various nuclear reactions, including fusion processes in the sun and other stars. Unlike protons, electrons, and neutrons, neutrinos have an extremely small mass and can pass through matter almost unaffected.

Question 4

The Sun's source of energy is&#10;A) fission of heavy elements.&#10;B) fusion of hydrogen into helium.&#10;C) combustion of hydrogen with oxygen.&#10;D) heat generated by gravity.

Accepted Answer

The Sun's energy is primarily produced through the fusion of hydrogen into helium in its core, a process that releases a tremendous amount of energy according to the principles of nuclear fusion.

Question 5

Based on our theory and observations we think the sun uses ______ cycle to produce energy.

Accepted Answer

The answer of Based on our theory and observations we...

Question 6

The sun produces the _____ neutrino in its fusion reactions.

Accepted Answer

The answer of The sun produces the _____ neutrino in...

Question 7

Cosmic rays are fast moving particles in space.

Accepted Answer

Cosmic rays are high-energy radiation, mainly originating outside the Solar System and even from distant galaxies, consisting of fast-moving particles such as protons, electrons, and atomic nuclei.

Question 8

The three-step process that creates energy in the sun is called the helium helium chain.

Accepted Answer

The process that creates energy in the sun is called the proton-proton chain, not the helium-helium chain. This process involves the fusion of hydrogen nuclei (protons) into helium.
