- Which interaction is responsible for radioactivity?
Weak force is responsible for radioactive decay.
Weak force is one of the four fundamental forces. It
is stronger than gravitational interaction. Weak
interaction is very effective in case of very short
distances. It’s a force present in the nucleus along
with strong interaction that helps bind the nucleus
and coulomb repulsive forces together. Well, weak
interaction helps transform neutron into a proton or
vice versa. What it really does is that it changes the
nature of the parent nucleus and changes the charge
of that by just one unit, ultimately leading to the
transformation of the parent nucleus. Were there no
weak interactions, the Sun wouldn’t be able to
convert hydrogen into deuterium, which is its
- Which particle mediates electromagnetic
Photon mediates electromagnetic interaction. In
order to answer the question, we first need to
understand what the word “mediate” means. Here
“mediate” means the carrier of the interaction. That
means there must be some carrier through which
electromagnetic radiation interacts between two
bodies. Photon helps in that. The momentum and
energy photons carry produce the effects of
- Which particle is the composition of two down
quarks and one up quark?
First of all, the charge of a down quark is -1e/3.
So two down quarks make -2e/3.
Now the charge of an up quark is +2e/3
Hence total charge of the composition =-2e/3+ 2e/3
Among all the options only neutron has zero charges.
So neutron is the answer.
- Which is not a baryonic matter in the options?
(Options are in the quiz 4 pages)
First of all Baryonic matter can be easily understood
as the matter that comprises baryons. Now, what are
baryons? Well, Baryons include neutrons, protons, and everything that is composed of them. So among
all the options neutrino is the one which isn’t made
of any neutrons or protons. It’s a sub-atomic
particle. So Neutrino is the one which isn’t baryonic.
- Which is called the “God Particle”?
Higgs boson is called the “God Particle”. Why is it
named the way it is? Well, the particle was
discovered with a lot of expense of billions and took
a lot of time. So it was called at first “Goddamn
Particle”. It was said as it was really difficult to
discover it at the time.
