Topic- Every day Physics-Base Quora QA-Compiled
Q1 Do aircraft become charged with static electricity during a
flight? If so, how do they discharge the aircraft?
KR Why daily physics is so seriously viewed because Gopala
was absorbed so deep in not knowing about it? Even your hair grows straight
when you go hear the switched off (just then) TV. It does not affect any
one so much. Now a class for compiler as his note at the end of his need
one; even after knowing it is useless he fills pages and still screams long
short etc.
Static electricity is the result of an imbalance between positive and
negative charges in objects. When certain materials come into contact and
then separate, electrons may transfer from one material to another, causing
a buildup of static charge. Here are the phenomena associated with static
electricity, along with its pros and cons:
Phenomena of Static Electricity:
Sparks and Discharges:
Example: When you touch a doorknob after walking on a carpet, you may feel
a spark or shock.
Cause: The sudden movement of electrons to balance the charge difference
between two objects.
Attraction and Repulsion:
Example: A balloon rubbed against hair sticks to a wall, or small pieces of
paper are attracted to a rubbed comb.
Cause: Objects with opposite charges attract each other, while those with
like charges repel.
Electrostatic Induction:
Example: Bringing a charged object near a neutral conductor induces a
redistribution of charges within the conductor without direct contact.
Cause: The electric field of the charged object influences the distribution
of charges in the nearby conductor.
Pros of Static Electricity: Applications in Technology:
Electrostatic Precipitators: Used in industrial processes to remove fine
particles from exhaust gases.
Xerography (Photocopying): Uses static charges to transfer toner to paper
to create images and text.
Everyday Uses: Dust Removal: Static electricity helps in attracting and
removing dust from surfaces.
Air Fresheners: Some air purifiers use static electricity to remove
pollutants from the air.
Scientific and Educational Tools:
Van de Graaff Generator: Demonstrates electrostatic principles and produces
high voltages for experiments.
Static Electricity Demonstrations: Used in classrooms to teach about
electricity and charge.
Cons of Static Electricity:
Safety Hazards:
Fire and Explosions: Static discharges can ignite flammable vapours or
dust, causing fires or explosions in industrial settings. (Plausible}
Electric Shocks: Unpleasant and sometimes dangerous shocks can occur when
touching metal objects after building up static charge.{Plausible}
Damage to Electronics:
Electrostatic Discharge (ESD): Can damage sensitive electronic components
during manufacturing or handling, leading to device failures. {RARE}
Data Loss: Static discharges can corrupt or erase data on electronic
storage devices. (Yes, in laptops; but can be revived back)
Discomfort and Inconvenience:
Static Cling: Clothes sticking together or to the body can be annoying.
Hair Static: Hair can become frizzy and difficult to manage due to static
electricity.
Mitigation and Control:
Grounding: Ensures that static charges are safely dissipated into the
ground, reducing the risk of shocks and damage.
Humidification: Increasing indoor humidity reduces static buildup, as
moisture helps dissipate static charges.
Anti-Static Products: Sprays, mats, and wrist straps designed to prevent
static charge buildup, especially in electronic manufacturing environments.
Understanding static electricity and managing its effects can help harness
its benefits while minimizing its drawbacks. {enough sir}

Q2 If you could be suspended above the earth, how fast would the
earth be moving below you?
Q A2 Silk Road, Physics Connoisseur, AI Machine Learning. Wed
KR Intelligent air framer? Silk Road is a scholar?
Now, if you were somehow suspended in space, outside the Earth's
atmosphere, you'd see the Earth rotate beneath you at its appropriate speed
for your latitude.
KR That is what Indian image of the earth is on a tortoise or
elephants outside; Atlas is holding from outside; and after seeing all a Q
and A, FOR A USELESS NOTHIG and the answer lacks physics totally; and lacks
the groove of daily physics hanging someone who can I hang? Compiler or
scholar?
------------------------------------------
Q3 What is the reason behind physicists believing that their field
is superior to others? Can mathematics be considered a science on par with
physics?
My note- Without Mathematics there is no Physics. 95% physics calculation
are based on Physics. So Physics depends on Mathematics. On this account in
our Universities, while Physics is main subject, ancillary is Mathematics.
Similarly Chemistry cannot be studied with out Physics.
KR Then why Gopala wasting time?
--------------------------------------------------------------
Q4 Which is more important to humanity; physics or chemistry?
KR: Having made note in Q2 why waste all our time?

Gopalakrishnan R. 29-06-2024
KR See when deranged mind reacts they scribble only as Q and A and
sign as Gopalakrishnan 29 6 2024 so that atleast others will know this line
is truth Thank you K I D
