Robert the Baldwin Family is anxiously awaiting the return of its head.” Who is the ‘head’ here

Robert Baldwin was fighting on two fronts at a time. He was very sincere and honest fellow. He was very loyal to his friendship and job as well. His friend was in the jail who wanted him to say in his favour. The family of Robert wanted to accept the money offered by John Gresham. Robert neither wanted to accept the money offered nor he wanted to witness in the court in the favour of John Gresham. Thus he was running under a mental tension.

रॉबर्ट बाल्डविन एक समय में दो मोर्चे पर लड़ाई लड़ रहा था। वह बहुत ईमानदार और गंभीर व्यक्ति था। वह अपनी नौकरी और मित्रता दोनों के प्रति वफादार था। उसका दोस्त जेल में था जो उसे उसके पक्ष में बोलने के लिए कहना चाहता था। रॉबर्ट का परिवार जॉन ग्रेशम द्वारा दिए जा रहे पैसे को स्वीकार करना चाहता था। रॉबर्ट न तो कोर्ट में जॉन ग्रेशम के पक्ष में गवाही देना चाहता था और न ही वह धन स्वीकार करना चाहता था। इस प्रकार से वह मानसिक तनाव में चल रहा था।

I don’t remember’ were the three words which Gresham wanted Baldwin to say when technical questions on misappropriation of funds are asked in the court. Gresham offered one hundred thousand dollars in hot cash to say them. But Baldwin did not want to do that dishonest and dishonourable thing.

The “Supreme Compliment” that of getting the position in the Third National.

“उच्चतम शुभकामना” थर्ड नेशनल में नौकरी पाने की थी।

Gresham wanted Baldwin to say three words “I don’t remember’ in the court when the lawyer (or) judge asked him the technical details and dates. If he did so, Gresham will not be indicted. In turn, Baldwin will get one hundred thousand dollars.

Mr. Gresham was charged with the wreck in the bank.

श्री ग्रेशम के खिलाफ बैंक में गबन का अपराध था।

10 मीटर = 10/100 किमी० = 0.01 किमी०

Martha had a doubt that the bank was crashing. So, she withdrew the money from the bank.

Baldwin advised Gresham to close the bank and make up the losses.

John had a feeling that his dad was paid only 60 dollars per week for the past 20 years. Gresham had become very rich during the same period. He deserved punishment for underpaying his staff.

Total cost of fencing the circular field = Rs. 2640

Cost per metre fencing = Rs 12

Total cost of fencing = circumference x cost per fencing

⇒ 2640 = circumference x 12

⇒ circumference = 2640/12=220m

Let radius of field be r m

Circumference = 2πr m

2πr = 220

2 x 22/7 x r = 220

r = 70/2=35m

Area of field = πr²

= 22/7x35x35

= 3850 m².

Cost of ploughing per m² land = Rs. 0.50

Cost of ploughing 3850 m² land = 1/2 x 3850

= Rs. 1925.

Total cost of fencing = Rs 2640 

Per meter rate of fencing = Rs 12 

So, 

Circumference of field = \(\frac{2640}{12}\) = 220 m

r = \(\frac{220\times7}{2\times22}\) = 35

Radius of field = 35 m 

Area of field = \(\frac{22}7\times35\times35\) = 3850 m² 

Cost of plugging 1 m² field = 0.50 Rs 

Total cost of plugging the field = 3850 × 0.50 

= Rs 1925.00

Given diameter of the well = 150 cm

Length of the outer edge of the parapet = 660 cm

Now we have to find width of the parapet

Now, radius of well = half of diameter = 150/2 = 75 cm

Consider the width of the stone parapet be x cm. then, according to the question outer edge of the parapet forms a circular region of radius (x + 75) cm

So, 660 = 2 × 22/7 × (x + 75)

(660 × 7)/ 2 × 22 = x + 75

4620/44 = x + 75

105 = x + 75

x = 105 – 75

x = 30

The width of the parapet = x = 30 cm

Given,

Width of hollow cylinder = 63 cm

Girth (perimeter) = 440 cm

Let external radius of cylinder = R cm

So, 2πr = 440

= R = \(\cfrac{440\times7}{2\times22}\) = 70 cm

= inner radius = outer radius – thickness = 70 – 4 = 66 cm

∴ volume of iron = π( R² - r²)h = \(\cfrac{22}7\times\)(70² - 66²)\(\times\)63

= \(\cfrac{22}7\times\)136\(\times\)4\(\times\)63 = 107712 cm³

Outer length, l = 25 cm. 

outer breadth, b = 85 cm. 

outer height, h = 110 cm. 

Outer surface area = lh + 2lb + 2bh = lh + 2(lb + bh) 

= 85 × 110 + 2(85 × 25 + 25 × 110) 

= 9350 + 9750 = 19100 cm² . 

Area of front face, 

= [85 × 110 – 75 × 100 + 2(75 × 5)] 

= (9350 – 7500 + 2(375)] 

= 9350 – 7500 + 750 

= 11000 – 7500 = 3500 cm² . 

Area to be polished, 

= 19100 + 3500 = 22600 cm² . 

Cost of polishing 1 cm³ is Rs. 0.20. 

Cost of polishing 22600 cm³ … ? … 

= 22600 × 0.20 = Rs. 4520. 

Length of horizontal shelf, l = 75 cm. 

breadth, b = 20 cm. 

height, h = 30 cm. 

Area of horizontal shelf = 2(l + h)b + lh 

= [2(75 + 30) × 20 + 75 × 30]

 = (4200 + 2250] cm² . = 6450 cm² . 

∴ Area of painting 3 horizontal rows 

= 3 × 6450 

= 19350 cm² . 

Cost of painting for 1 cm³ is Rs. 0.10. 

∴ Cost of painting 19350 cm³ … ? 

= 19350 × 0.10 = Rs. 1935. 

∴ Total cost of polish and painting 

= Rs. 4520 + Rs. 1935 

= Rs. 6455.

Dr’s are (7,-5,1), and (1, 2, 3) 

a₁b₁+ a₂b₂ + a₃b₃ 

7 x 1 - 5 x 2 + 1 x 3

The position vector of given points A and B are respectively (3i - j + 7k and -i + 5j + 7k)

Let P be any point on the plane with position vector xi + 5j + 2k

So, vector AP = (x - 3)i + (y + 5)j + (z + 1)k and AB = -4i + 10j + 8k

Clearly, vector(AP, AB) and given vector 3i - j + 7k are co-planar, 

So, equation of the require plane is

|(x - 3,y + 5,z + 1),(-4,10,8),(3,-1,7)| = 0

78(x - 3) + 52(y + 5) - 26(z + 1) = 0 

78x + 52y - 26z = 0 

3x + 2y - z = 0

The vector equation of require plane is

vector r.(3i + 2j - k) = 0

The distance between the Sun and the Earth is 1.496 x 10 s km

= 1.496 x 10⁸ x 10³ m 

= 1496 x 10⁸ m

The distance between the Earth and the Moon is 3.84 x 10⁸ m.

The distance between the Moon and the Sun at particular time (solar eclipse) = (1496 x 10⁸- 3.84 x 10⁸)m = 1492. 16 x 10⁸ m

Air drag plays a large role in slowing bike riders (especially, bicycle) down. Hence, a helmet is aerodynamically shaped so that it does not cause too much drag.

Clouds are composed of tiny water droplets. Since, terminal velocity is proportional to the square of radius, the terminal velocity of tiny droplets is too small. The clouds thus attain terminal velocity much before they reach ground.

Blades of a ceiling/table fan have uniform thickness (unlike that of an aerofoil) but are angled (cambered) at 8° to 12° (optimally, 10°) from their plane. When they are set rotating, this camber causes the streamlines above/behind a fan blade to detach away from the surface of the blade creating a very low pressure on that side. The lower/front streamlines however follow the blade surface. Dust particles stick to a blade when it is at rest as well as when in motion both by intermolecular force of adhesion and due to static charges. However, they are not dislodged from the top/behind surface because of complete detachment of the streamlines.

The lower/front surface retains some of the dust because during motion, a thin layer of air remains stationary relative to the blade.

The streamline shape of cars and birds reduce drag.

Cars and aeroplanes are given streamline shape to minimize the backward drag of atmosphere.

The surface of a liquid open to the atmosphere is called the free surface of the liquid.

Latent heat energy is the heat energy required to change the state of 1 kg of substance from one to another at constant temperature

When two conduction are placed on the side of each other with their ends at the same reservoirs of heat then, 

(a) Difference in temperature is same. 

(b) The total rate of heat transfer is the is the sum of the heat transfer in them. 

(c) The equivalent thermal resistance is found from

\(\frac{1}{R_{eq}}=\frac{1}{R_1}+\frac{1}{R_2}\)

Mechanical equivalent is the amount of work done to produce one unit of heat energy. It is 4.186 Joule of heat.

It is a device used to measure the temperature of a body. It makes use of some measurable property (called thermometric property) of a substance which changes linearly with temperature.

It is the degree of hotness of a body. The temperature of a body gives a measure of the average kinetic energy of its molecules.

Whenever a given amount of work (W) is converted into heat, always the same amount of heat Q is produced. 

J = W/Q 

W = JQ 

The proportionally constant J is called Joule’s mechanical equivalent of heat. It may be defined as the amount of work that must be done to produce a unit quantity of heat.
