No, I do not agree with this statement because of the reasons mentioned below:
(a) The tertiary sector or the service sector in India employs many different kinds of people.
(b) This sector has now become the largest producing sector in India by replacing the primary sector. The share of tertiary sector in GDP is now more than 50%.

Let us consider a liquid of density ρ in a vessel as shown in figure. Let us find the pressure difference between two points A and B separated by vertical height h.
To evaluate the pressure difference between A and B, consider an imaginary cubiod of area of cross-section a of liquid with upper and lower cap passing through A and B respectively. The volume of the imaginary cylinder is,.
V=ah
Mass of liquid of imaginary cylinder is,
m = ρah
Let P1 and P2 be the pressure on the upper and lower face of cylinder. The different forces acting on the imaginary cylinder are:
(i) weight mg = ρahg in vertically downward direction.
(ii) Downward thrust of F1 =P1a on upper cap.
(iii) Upward thrust of F2 = P2a on lower face. As the imaginary cylinder in the liquid is in equilibrium, therefore the net force on the cylinder is zero, i.e.
Thus the pressure difference between two points separated vertically by height h in the presence of gravity is ρgh. In the absence of gravity this pressure difference becomes zero.

Dog
The first animal to actually go into orbit was the dog Laika, launched on board the Soviet Sputnik 2 spacecraft on November 3, 1957. Unfortunately, Laika died during the flight.
At least 10 more dogs were launched into space and on sub-orbital flights by the Soviets until April 12, 1961, when Yuri Gagarin became the first human in space.

Trapezium:
- Like other quadrilaterals, the sum of all the four angles of the trapezium is equal to 360°
- A trapezium has two parallel sides and two non-parallel sides
- The diagonals of regular trapezium bisect each other
- The length of the mid-segment is equal to half the sum of the parallel bases, in a trapezium
- Two pairs of adjacent angles of a trapezium formed between the parallel sides and one of the non-parallel side, add up to 180 degrees.
Rhombus:
- All sides of the rhombus are equal.
- The opposite sides of a rhombus are parallel.
- Opposite angles of a rhombus are equal.
- In a rhombus, diagonals bisect each other at right angles.
- Diagonals bisect the angles of a rhombus.
Parallelogram:
- The opposite sides are congruent.
- The opposite angles are congruent.
- The consecutive angles are supplementary.
- If anyone of the angles is a right angle, then all the other angles will be the right angle.
- The two diagonals bisect each other.
- Each diagonal bisects the parallelogram into two congruent triangles.

एक बार लेखक अपने चार मित्रों के साथ बस से जबलपुर जाने वाली ट्रेन पकड़ने के लिए अपनी यात्रा बस से शुरु करने का फैसला लेते हैं। परन्तु कुछ लोग उसे इस बस से सफर न करने की सलाह देते हैं। उनकी सलाह न मानते हुए, वे उसी बस से जाते हैं किन्तु बस की हालत देखकर लेखक हंसी में कहते हैं कि बस पूजा के योग्य है।
नाजुक हालत देखकर लेखक की आँखों में बस के प्रति श्रद्धा के भाव आ जाते हैं। इंजन के स्टार्ट होते ही ऐसा लगता है की पूरी बस ही इंजन हो। सीट पर बैठ कर वह सोचता है वह सीट पर बैठा है या सीट उसपर। बस को देखकर वह कहता है ये बस जरूर गाँधी जी के असहयोग आंदोलन के समय की है क्योंकि बस के सारे पुर्जे एक-दूसरे को असहयोग कर रहे थे।
कुछ समय की यात्रा के बाद बस रुक गई और पता चला कि पेट्रोल की टंकी में छेद हो गया है। ऐसी दशा देखकर वह सोचने लगा न जाने कब ब्रेक फेल हो जाए या स्टेयरिंग टूट जाए।आगे पेड़ और झील को देख कर सोचता है न जाने कब टकरा जाए या गोता लगा ले।अचानक बस फिर रुक जाती है। आत्मग्लानि से मनभर उठता है और विचार आता है कि क्यों इस वृद्धा पर सवार हो गए।
इंजन ठीक हो जाने पर बस फिर चल पड़ती है किन्तु इस बार और धीरे चलती है।आगे पुलिया पर पहुँचते ही टायर पंचर हो जाता है। अब तो सब यात्री समय पर पहुँचने की उम्मीद छोड़ देते है तथा चिंता मुक्त होने के लिए हँसी-मजाक करने लगते है।अंत में लेखक डर का त्याग कर आनंद उठाने का प्रयास करते हैं तथा स्वयं को उस बस का एक हिस्सा स्वीकार कर सारे भय मन से निकाल देते हैं।

When the temperature of the heater becomes greater than the temperature of the surrounding, some of the heat is lost to the surroundings in the form of thermal radiations.
After some time, rate at which heat is being produced becomes equal to the rate of which heat is lost. Hence, the temperature of the element becomes constant.

Speed after 25 s = 180 km/h = 180 ×(5/18) m/s = 50 m/s
From equation v = u + a t , we get acceleration. where v is final speed, u is initial speed which is zero because
the car strats from rest, a is acceleration and t is time taken to attain the final speed.
hence v = a t or 50 = a×25 or acceleration a = 50/25 = 2 m/s2 .
distance travelled, S = (1/2)a t2 = (1/2)×2×25×25 = 625 m
