A teacher has to know how to listen. Because his first role is listening to others, and assisting them. I know a nice number of teachers who know how to listen to their students, their families, other colleagues, admins, and everybody else. The teacher will listen to the kids for example, in an attentive way, realizing and learning whatās going on with their lives at the school ā with prudence anyway. At the beginning of the school year he learns their names quite nicely, because he gets interested in the persons he has in charge. He doesnāt confine his job to teaching and disappearing through the door when his āblockā has been delivered to his students. Heās prone to take in charge his studentsā issues, problems and joys alike. He teaches with high standards of professionalism and with affection, with a clever and insightful affection ā with prudence anyway.

Teaching Experience in detail in Spoken English classes
I started my teaching career in 2015 working for a few privately-working language people. I taught a number of hours in each place, so spent most of my day on the metro getting from one side of the city to the other. Getting your foot in the door was how it worked back then, and to be honest, little has changed there regarding working in big cities. Before going solo I explored my city and worked Nationally as an english to hindi dubbing script writer. I did this to perfect my language & related skills. It worked in as far as learning Skills, but being a student has its age limitations, and knowing that I wanted to travel and learn more languages led me to going on my own. My other work experiences involved tutoring school and college students for different subjects in both the languages English/Hindi as convenient. I manage groups of people from different backgrounds, learning styles and cultures who have to work together constructively over short, intense periods of time. This can get sticky, so a sense of calm and humour is essential. Listening and providing a pastoral ear is also key, as well as being 100% open and objective to what may come up. When training I might be observing lessons, helping people in their planning, marking essays and even teaching myself as well as answering emails from previous trainees with their eclectic questions.

Answered on 18/09/2018 Learn CBSE/Class 11/Science/Physics/Unit 4-Motion of System of Particles/Chapter 7-System of Particles and Rotational Motion
Let m and r be the respective masses of the hollow cylinder and the solid sphere.
The moment of inertia of the hollow cylinder about its standard axis, I1 = mr2
The moment of inertia of the solid sphere about an axis passing through its centre, I2 = (2/5)mr2
We have the relation:
τ = Iα
Where,
α = Angular acceleration
τ = Torque
I = Moment of inertia
For the hollow cylinder, τ1 = I1α1
For the solid sphere, τn = Inαn
As an equal torque is applied to both the bodies, τ1 = τ2
∴ α2 / α1 = I1 / I2 = mr2 / (2/5)mr2
α2 > α1 …(i)
Now, using the relation:
ω = ω0 + αt
Where,
ω0 = Initial angular velocity
t = Time of rotation
ω = Final angular velocity
For equal ω0 and t, we have:
ω ∝ α … (ii)
From equations (i) and (ii), we can write:
ω2> ω1
Hence, the angular velocity of the solid sphere will be greater than that of the hollow cylinder.

Let at a certain instant two particles be at points P and Q, as shown in the following figure.
Lp = mv × 0 + mv × d = mvd …(i)
Angular momentum of the system about point Q:
LQ = mv × d + mv × 0 = mvd ….(ii)
Consider a point R, which is at a distance yfrom point Q, i.e.,
QR = y
∴ PR = d – y
Angular momentum of the system about point R:
LR = mv × (d – y) + mv × y
mvd – mvy + mvy
= mvd ….(iii)
Comparing equations (i), (ii), and (iii), we get:
LP = LQ = LR …(iv)
We infer from equation (iv) that the angular momentum of a system does not depend on the point about which it is taken.

Mass of the cylinder, m = 10 kg
Radius of the cylinder, r = 15 cm = 0.15 m
Co-efficient of kinetic friction, µk = 0.25
Angle of inclination, θ = 30°
Moment of inertia of a solid cylinder about its geometric axis, I = (1/2)mr2
The various forces acting on the cylinder are shown in the following figure:
a = mg Sinθ / [m + (I/r2) ]
= mg Sinθ / [m + {(1/2)mr2/ r2} ]
= (2/3) g Sin 30°
= (2/3) × 9.8 × 0.5 = 3.27 ms-2
(a) Using Newton’s second law of motion, we can write net force as:
fnet = ma
mg Sin 30° – f = ma
f = mg Sin 30° – ma
= 10 × 9.8 × 0.5 – 10 × 3.27
49 – 32.7 = 16.3 N
(b) During rolling, the instantaneous point of contact with the plane comes to rest. Hence, the work done against frictional force is zero.
(c) For rolling without skid, we have the relation:
μ = (1/3) tan θ
tan θ = 3μ = 3 × 0.25
∴ θ = tan-1 (0.75) = 36.87°.

A body rolling on an inclined plane of height h,is shown in the following figure:
R = Radius of the body
K = Radius of gyration of the body
v = Translational velocity of the body
h =Height of the inclined plane
g = Acceleration due to gravity
Total energy at the top of the plane, E1= mgh
Total energy at the bottom of the plane, Eb = KErot + KEtrans
= (1/2) I ω2 + (1/2) mv2
But I = mk2 and ω = v / R
∴ Eb = (1/2)(mk2)(v2/R2) + (1/2)mv2
= (1/2)mv2 (1 + k2 / R2)
From the law of conservation of energy, we have:
ET = Eb
mgh = (1/2)mv2 (1 + k2 / R2)
∴ v = 2gh / (1 + k2 / R2)
Hence, the given result is proved.
