Thoughts on Higgs Boson
When it is not contested scientifically that change is a continuous phenomenon,how is that Higgs boson, if found,can be considered as the ultimate building block of matter.
Sure, it may prove a mathematically arrived conclusion… yet the contradiction remains.
An ever changing, at the same time, ever stable (because it is the ultimate one) is the contradiction.
One may find changing or divisible particle only…

Doubts from Faraday’s Experiments on electromagnetic induction
I wanna ask that in faradays’s first experiment with coil and magnet,when the magnet is moved away from coil the deflection in galvanometer becomes opposite as compared to first case…..what leads to this and if that means direction of current becomes opposite so HOW and WHY the direction of this changes…..plz can you tell me the practical reason of this…..its really confusing me!!!

Problem from Kinematics
The speed of a train changes from36km/h to 72km/h in 10sec. calculate the distance travelled during this time
Answer:
u=36km/h = 10 m/s
v=72 km/h=20 m/s
t=10 s
S=?
use v = u+ at to find a
a = 1 m/s2
Use v2-u2=2aS to find S
S = (400-100)/2 = 150 m

How to get A in physics?
Nischal Singh Dangol Asked:
How to get A in physics?
Answer:
Whatever the syllabus or course, an A grade means “Excellent work indicating a clear mastery of the subject material”
This requires evidently a basic understanding of the subject, thorough with the fundamentals and the ability to apply the principles to solve problems creatively. One should be able to make suitable connections between concepts logically to solve the problem in hand. (Remember, Physics is often referred to as a Problem Solving Discipline)
A grade in Physics comes naturally if you start loving the subject and take active interest in applying the concepts of Physics to solve problems (in subject as well as in day to day life situations)
Also important :
- Maintaining good rapport is also important in getting an A grade.
- Attend all lectures/classes and never bunk
- Do your assignments sincerely and submit in time
Wish you all the best.
