Fundamental Forces
- The
four fundamental forces of nature such as electromagnetic, gravitational,
strong nuclear forces, and weak nuclear forces.
- The
photon is a particle of spin equal to one unit that mediates the
electromagnetic interaction or force.
- Gauge
bosons act as intermediaries and mediate other interactions such as strong
interactions, weak interactions, etc.
- The
event horizon represents the distance of approach beyond which even light
cannot escape.
- If
an object or particle enters the event horizon surrounding a black hole,
it cannot ever escape the gravitational pull of the black hole.
Question-7

Twin tropical cyclones are caused
by equatorial Rossby waves, which are huge waves with wavelengths around
4,000-5,000 Kms.
2.
Twin cyclones always move into
different hemispheres, the northern hemisphere cyclone will move north and
east, while the southern one will move south and west.
Which of the above statement(s)
is/are correct?
a)
1 only
b)
2 only
c)
Both 1 and 2
d)
Neither 1 nor 2
Ans-a
Explanation-
Cyclone Asani, active now in the
Bay of Bengal, has a twin — cyclone Karim — in the southern hemisphere.
Twin Cyclones
- The interplay of the wind and the monsoon
system combined with the Earth system produces these synchronous cyclones.
- Twin tropical cyclones are caused by what
are called equatorial Rossby waves.
- Rossby waves are huge waves in the ocean
with wavelengths of around 4,000–5,000 kilometers.
- This system has a vortex in the northern
hemisphere and another in the southern hemisphere, and each of these is a
mirror image of the other.
- The vortex in the north spins
counterclockwise and has a positive spin.
- While the one in the southern hemisphere
spins in the clockwise direction and therefore has a negative spin.
- Both have a positive value of the
vorticity which is a measure of the rotation.
Will the two cyclones of the pair
necessarily move into different hemispheres?
- Once these cyclones form, generally, they
will go westward.
- In the northern hemisphere, they will
have a slightly northward component of motion.
- Whereas, in the southern hemisphere, they
will usually have a slightly southward component to their movement.
- So this means the northern hemisphere
cyclone would go North and West, while the southern one would go South and
West.
Question-8
Consider the following statements:
1.
The gravitational force tugging
between two bodies depends on how massive each one is and how far apart the two
lie.
2.
Space and time are interwoven, and
events that occur at the same time for one observer could occur at different
times for another.
Which of the above statement(s)
is/are correct?
a)
1 only
b)
2 only
c)
Both 1 and 2
d)
Neither 1 nor 2
Ans-c
Explanation-
Astronomers reveal the first image
of the black hole at the heart of the Milky Way galaxy.
Theory of relativity
Newton
- Gravity is the force of attraction that
two objects exert on one another.
- Newton quantified gravity and formulated
the three laws of motion.
- The gravitational force tugging between
two bodies depends on how massive each one is and how far apart the two
lie, according to NASA.
- Even as the center of the Earth is
pulling you toward it (keeping you firmly lodged on the ground), your
center of mass is pulling back at the Earth.
- But the more massive body barely feels
the tug from you, while with your much smaller mass you find yourself
firmly rooted thanks to that same force.
- Yet Newton's laws assume that gravity is
an innate force of an object that can act over a distance.
Einstein
- Albert Einstein, in his theory of special
relativity, determined that the laws of physics are the same for all
non-accelerating observers, and he showed that the speed of light within a
vacuum is the same no matter the speed at which an observer travels,
according to Wired.
- Einstein found that space and time were
interwoven into a single continuum known as space-time.
- And events that occur at the same time
for one observer could occur at different times for another.
- Einstein realized that massive objects
caused a distortion in space-time.
- Light bends around a massive object, such
as a black hole, causing it to act as a lens for the things that lie
behind it.
Question-9
Consider the following statements:
1.
It is the world’s smallest marine
mammal.
2.
It has been classified as
critically endangered by the IUCN.
3.
They are now found only in the
Gulf of California, Mexico.
Identify the species.
a)
Vaquita
b)
Sea otter
c)
Weasel
d)
Tarsier
Ans- a
Explanation-
Vaquita
- The vaquita porpoise is the world's
smallest marine mammal and is believed to be on the brink of extinction,
with 10 or fewer still living in Mexico's Gulf of California, their sole
habitat.
- This little porpoise wasn't discovered
until 1958 and a little over half a century later, we are on the brink of
losing them forever.
- Vaquita is often caught and drowned in
gillnets used by illegal fishing operations in marine protected areas
within Mexico's Gulf of California.
- The population has dropped drastically in
the last few years.
- Characteristics
- The vaquita has a large dark ring around
its eyes and dark patches on its lips that form a thin line from the mouth
to the pectoral fins.
Question-10
Consider the following statements
regarding Protected Mobility Vehicles (PMV):
1.
It has ballistic protection and is
unaffected by grenade and mine blasts, used in high-altitude and desert areas.
2.
It is manufactured by DRDO in
collaboration with the Israel defense ministry.
Which of the above statement(s)
is/are correct?
a)
1 only
b)
2 only
c)
Both 1 and 2
d)
Neither 1 nor 2
Ans- a
Explanation-
Protected Mobility Vehicles (PMV)
- The PMV is essentially a wheeled armored
personnel carrier.
- It provides protection to the soldiers
traveling inside the vehicle from mine blasts and sudden attacks by small
arms.
- The troops in these vehicles could be
members of any quick reaction team heading to a point of conflict, or
members of patrolling parties heading to border areas.
- These vehicles are wheeled, in 4X4 drive
mode, and should have automatic transmission.
- These vehicles have the capacity to carry
ten personnel excluding the driver and co-driver with each person carrying
a combat load of not less than 30 kg.
- They have ballistic protection and should
be able to protect the vehicle from grenade and mine blasts.
- It has a maximum speed of 90km on road
and 40km per hour on cross-country terrain.
- They also operate in the temperature
range of 40 degrees centigrade to minus 15 degrees in high-altitude areas.
