Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

Avatar Sir , I have a question

 


( aka Dronacharya V 2.0 )

 

Thousands of years ago, SC / ST class Eklavya approached Guru Dronacharya to

 teach him archery


Dronacharya turned him down saying he taught only sons of kings

 

Disappointed Eklavya returned to his jungle cottage but instead of feeling

disheartened, he sculpted a statue of the Guru in dry grass , installed it on a

pedestal , bowed in reverence and started shooting arrows at distant

targets


 

He repeated this exercise day long, for years on end, till he mastered archery

even better than those sons of Kings


 

5,000 years after the Mahabharat , this drama could have a redux in the form of

my Virtual Avatar

www.HemenParekh.ai

 

Approx. 13 lakh schools are located in our 6.64 lakh villages – many without a

single teacher and some with just 1 or 2 teachers


 

Even in those having a couple of teachers, the quality of teaching is miserably

outdated

 

In the absence of PHYSICAL and COMPETENT teachers, can TECHNOLOGY fill the

vacuum ?

 

I think so ( - provided , the new government at the Centre has a will to help the

underprivileged village children )


 

Here is how :

 

Under government’s BharatNet project , as of today, some 200,000 gram-

panchayats ( out of targeted 250,000 ), have been connected to internet via

Optical Fibre Cable ( OFC )


This OFC provides a bandwidth of 100 mbps ( pretty good )

 

Let govt provide FREE Smart phones or Tablets, to the students of these schools (

by no means a FREEBIE ,nor included in BJP’s Sankalp Patra ).

 

 

Include this item in 100 DAYS ROAD-MAP

 

Then these children will ask www.HemenParekh.ai ( Dronacharya 2.0 ) following (

sample for illustration ) questions ( in local language ) and get correct replies (

better than those highly paid / competent teachers of elite city schools )

 

I have taken only 5 questions from PHYSICS syllabus of 10th standard but it could

be 50 questions for ANY subject and for ANY standard ( from 1st to 10th ) . I have

not tried questions for college degrees in ANY discipline



And the ICING on the CAKE is :

 

Students can “ ask “ questions by simply “ talking “ ( in chosen language ) and

get to “ listen “ to the answers !

 

And they can enjoy this “ teaching “ by their VIRTUAL TEACHER, whether in school

or at home.

 

Do send me your suggestions for improvement on > hcp@RecruitGuru.com

Question

Answer from my Avatar

 

 

State the laws of reflection of light

When light reflects off a surface, it follows two important laws: the angle of incidence is equal to the angle of reflection, and the incident ray, reflected ray, and normal to the surface all lie in the same plane.

 

 

A car accelerates from rest at a rate of 5 m/s². If it reaches a speed of 20 m/s in 4 seconds, calculate the distance traveled by the car in those 4 seconds.

The distance traveled by the car can be calculated using the formula: distance = (initial velocity * time) + (0.5 * acceleration * time^2). Plugging in the values, we get: distance = (0 * 4) + (0.5 * 5 * 4^2), which simplifies to: distance = (0) + (0.5 * 5 *16), and finally gives us: distance = 40 meters.

 

 

Define electric current. List two factors on which the resistance of a wire depends.

Electric current is the flow of electric charge through a conductor. It is measured in amperes (A). The resistance of a wire depends on its length and cross-sectional area. The longer the wire, the higher the resistance, and the smaller the cross-sectional area, the higher the resistance.

 

 

Explain how an electromagnet works. Describe one application of electromagnets in our daily lives.

Electromagnets work by creating a magnetic field when an electric current flows through a coiled wire. This magnetic field can attract or repel other objects, depending on the polarity. One common application of electromagnets in our daily lives is in electric doorbells, where the chime is attracted to the magnet when the circuit is completed.

 

 

Differentiate between potential energy and kinetic energy. Give an example of each type of energy.

Potential energy is the stored energy an object has because of its position or state, such as a ball held above the ground. Kinetic energy is the energy possessed by a moving object, like a car in motion. Do you have any other questions about different types of energies?

Being lazy and old ( 91 years ) , I have just reproduced in the table below, these

questions in English


But these question too will appear in the HINDI script , if you first select “ Hindi “

as your choice and then SPEAK the concerned question in English. It will get

translated into HINDI script, automatically  


Question

Answer

 

 

State the laws of reflection of light

प्रकाश के परावर्तन के नियम बताते हैं कि आपतन कोण परावर्तन कोण के बराबर होता है, और आपतित किरण, परावर्तित किरण और आपतन बिंदु पर अभिलंब सभी एक ही तल में होते हैं। इन कानूनों की खोज सबसे पहले किसने की?

 

 

A car accelerates from rest at a rate of 5 m/s². If it reaches a speed of 20 m/s in 4 seconds, calculate the distance traveled by the car in those 4 seconds.

कार द्वारा तय की गई दूरी की गणना सूत्र का उपयोग करके की जा सकती है: दूरी = (प्रारंभिक वेग * समय) (0.5 * त्वरण * समय^2)। इस मामले में, चूंकि कार आराम से शुरू होती है, प्रारंभिक वेग 0 मीटर/सेकेंड है। मान जोड़ने पर, हमें मिलता है: दूरी = (0 * 4) (0.5 * 5 * 4^2) = (0) (2.5 *16) = 40 मीटर।

 

 

Define electric current. List two factors on which the resistance of a wire depends.

विद्युत धारा एक चालक के माध्यम से विद्युत आवेश का प्रवाह है, जिसे एम्पीयर (ए) में मापा जाता है। किसी तार का प्रतिरोध उसकी लंबाई और क्रॉस-सेक्शनल क्षेत्र पर निर्भर करता है। ये दो कारक तार के समग्र प्रतिरोध को निर्धारित करने में महत्वपूर्ण भूमिका निभाते हैं।

 

 

Explain how an electromagnet works. Describe one application of electromagnets in our daily lives.

जब तार की कुंडली से विद्युत धारा प्रवाहित होती है तो विद्युत चुम्बक एक चुंबकीय क्षेत्र बनाकर कार्य करते हैं। यह चुंबकीय क्षेत्र ध्रुवता के आधार पर अन्य वस्तुओं को आकर्षित या विकर्षित कर सकता है। हमारे दैनिक जीवन में विद्युत चुम्बकों का एक सामान्य अनुप्रयोग विद्युत दरवाजे की घंटियों में होता है, जहाँ चुम्बक बजने वाली ध्वनि पैदा करने के लिए एक धातु की पट्टी को आकर्षित करता है और छोड़ता है।

 

 

Differentiate between potential energy and kinetic energy. Give an example of each type of energy.

संभावित ऊर्जा वह संग्रहीत ऊर्जा है जो किसी वस्तु में उसकी स्थिति या स्थिति के कारण होती है, जैसे कि जमीन के ऊपर रखी गेंद। गतिज ऊर्जा वह ऊर्जा है जो किसी गतिशील वस्तु, जैसे लुढ़कती हुई गेंद, में होती है। संभावित ऊर्जा का एक उदाहरण एक फैला हुआ रबर बैंड है, जबकि गतिज ऊर्जा का एक उदाहरण एक चलती कार है।
