Mundaka Upanishad

The correct answer is Mundaka.

• The words Satyameva Jayate from Mundaka Upanishad, meaning 'Truth Alone Triumphs', are inscribed below the abacus in Devanagari script.

• The state emblem is an adaptation from the Sarnath Lion Capital of Ashoka.
  • In the original, there are four lions, standing back to back, mounted on an abacus with a frieze carrying sculptures in high relief of an elephant, a galloping horse, a bull, and a lion separated by intervening wheels over a bell-shaped lotus.
  • Carved out of a single block of polished sandstone, the Capital is crowned by the Wheel of the Law (Dharma Chakra)
  • In the state emblem, adopted by the Government of India on 26 January 1950, only three lions are visible, the fourth being hidden from view.
  • The wheel appears in relief in the centre of the abacus with a bull on right and a horse on the and the outlines of other wheels on the eme right and left.
  • The bell-shaped lotus has been omitted.

Eutrophication refers to the nutrient enrichment in water bodies leading to lack of oxygen . and will end up in the death of aquatic organisms. 

Algal Bloom is an excess  growth of algae due to abundant excess nutrients imparting distinct color to water.

(d) Gathering and analyzing market information

The decision taken by the school authority to refuse admission for AIDS-affected children is totally wrong. 

This is because AIDS is not a communicable disease.

Therefore AIDS vims will not be transferred through touching or sharing food, water, air etc.

Correct option is D) litter

[Hint : Because F does not show oxidation state other than -1.]

Significant figures are the digits of a number that are meaningful in terms of accuracy or precision.

Every scientific measurement involves some degree of uncertainty. In order to report a measurement correctly and precisely, the scientists use the concept of significant figures. The significant figures are defined as the total number of certain digits plus one doubtful digit in a number expressing a measurement. For illustration of this term, let us suppose that we want to measure the mass of an object with the help of an analytical balance. Let us further suppose that the measured mass of the object comes out to be 30.1296 g. Now, the analytical balance can record the mass of the object to a sensitivity of 0.0001 g. Thus, all the figures reported are significant. The reported value (30.1296 g) has six significant. figures. Though the last figure has some uncertainty but even then it is significant. Because this implies that the true mass of the object lies closer to 30.1296 g than to 30.1295 g or 30.1297 g. This is the most precise value of the mass measured with analytical balance.

Tribasic acid is H₃PO₄

(I) 

1. The polarity of a covalent bond can be measured in terms of dipole moment which is defined as: m = q × 2d, where m is the dipole moment, q is the charge, 2d is the distance between the two charges. 

2. The dipole moment is a vector quantity and the direction of the dipole moment points from the negative charge to positive charge. 

3. The unit of dipole moment is Coulomb metre (C m). It is usually expressed in Debye unit (D). 

4. 1 Debye = 3.336 × 10^-30 C m

(II)

1. The ability of a cation to polarise an anion is called its polarising ability and the tendency of ah anion to get polarised is called its polarisibility. The extent of polarisation in an ionic compound is given by the Fajans rule. 

2. To show greater covalent character, both the cation and anion should have high charge on them. Higher the positive charge on the cation greater will be the attraction on the electron cloud of the anion. Similarly higher the magnitude of negative charge on anion, greater is its polarisability. 

For example, Na⁺ < Mg²⁺ < Al³⁺,

the covalent character also follows the order: 

NaCl < MgCl₂< AlCl₃.

3. The smaller cation and larger anion show greater covalent character due to the greater extent of polarisation, e.g., LiCl is more covalent than NaCl.

4. Cation having ns² np⁶ nd⁰ configuration shows greater polarising power than the cations with ns² np ⁶configuration, e.g., CuCl is more covalent than NaCl.

Correct answer is 3

Square pyramidal structures are

BrF₅, IF₅ and ClF₅.

Given:

X can fill the tanker in 20 minutes and Y can empty it in 30 minutes.

Concept:

If a tap can fill a tank in x hours, then the tank filled by the tap in 1 hour = 1/x of the total tank.

Calculation:

Part of the tanker filled in first 2 minutes

⇒ \(\frac{1}{{20}} - \frac{1}{{30}}{\rm{}} = {\rm{}}\frac{{3 - 2}}{{60}}{\rm{}} = {\rm{}}\frac{1}{{60}}\)

Part of tanker filled in 114 minutes

⇒ \(\frac{{57}}{{60}}\)

⇒ \(\frac{{19}}{{20}}\)

∴ Remaining part of tanker will be filled in 115^th minutes.

Correct option is A) gave them to him

Given:

Time taken by pipe A to fill the tanker = 4 hrs

Time taken by pipe B to fill the tanker = 8 hrs

Time taken by pipe C to fill the tanker = 12 hrs

Time taken by pipe D to empty the tanker = 10 hrs

Concept:

If a tap can fill a tank in x hours, then the tank filled by the tap in 1 hour = 1/x of the total tank.

Calculation:

Option 1:

Part of the tanker filled in 1 hours when pipes B is open alone

⇒ 1/8

Hence, the tanker will be filled in 8 hours

Option 2:

Part of the tanker filled in 1 hours when pipes A and D are open

⇒ \(\frac{1}{4} - \frac{1}{{10}}{\rm{}} = {\rm{}}\frac{{5 \;-\; 2}}{{20}}{\rm{}} = {\rm{}}\frac{3}{{20}}\)

Hence, the tanker will be filled in \(\frac{{20}}{3}\) hours = 6.6 hours

Option 3:

Part of the tanker filled in 1 hours when pipes A, C and D are open

⇒ \(\frac{1}{4}{\rm{}} + {\rm{}}\frac{1}{{12}} - \frac{1}{{10}}\)

⇒ \(\frac{{15{\rm{\;}} + {\rm{\;}}5 - 6}}{{60}}{\rm{}} = {\rm{}}\frac{{14}}{{40}}{\rm{}} = {\rm{}}\frac{7}{{30}}\)

Hence, the tanker will be filled in \(\frac{{30}}{7}\) hours = 4.3 hours

Option D:

Part of the tanker filled in 1 hours when pipes A, B and D are open

⇒ \(\frac{1}{4}{\rm{\;}} + {\rm{\;}}\frac{1}{8} - \frac{1}{{10}}\)

⇒ \(\frac{{10{\rm{\;}} + {\rm{\;}}5 - 4}}{{40}}{\rm{}} = {\rm{}}\frac{{11}}{{40}}\)

Hence, the tanker will be filled in \(\frac{{40}}{{11}}\) hours = 3.6 hours

∴ Tanker can be filled faster when A, B and D are open.

Given:

A pipe can fill a bucket in P hours and another can empty in Q hours.

Concept:

If a tap can fill a tank in x hours, then the tank filled by the tap in 1 hour = 1/x of the total tank.

Calculation:

When both pipe are opened simultaneously, part of the bucket filled in 1 hours

⇒ \(\frac{1}{{\rm{P}}} - \frac{1}{{\rm{Q}}}{\rm{}} = {\rm{}}\frac{{{\rm{Q}} - {\rm{P}}}}{{{\rm{PQ}}}}\)

∴ Required time is \(\frac{{{\bf{PQ}}}}{{{\bf{Q}} - {\bf{P}}}}\) hours.

The answer of this riddle is 7.

Explanation :-

There are 7 candles lit and if I blew out 2 of them , I still have 7 Candles 5 lit and 2 unlit.

But still there is catch, if those 5 candles are lit longer, they will melt and we will be left with 2 candles.

So, Depending on the time when we count the candles answer would be either 7 or 2.

Since, in the riddle it is not explicitly stated the time, answer is 7.

If 2 candles blew out we are still left with 7 candles out of which 5 are lit and 2 candles that are extinguished.

But still there is catch, if those 5 candles are lit longer, they will melt and we will be left with 2 candles

Depending on when it is counted, we are left with either 7 or 2 candles

Correct option is A) put them there

Given:

Two pipes J and K can separately fill a pot in 2 hours and 3 hours respectively.

Concept:

If a tap can fill a tank in x hours, then the tank filled by the tap in 1 hour = 1/x of the total tank.

Calculation:

Part of the pot filled by pipes J and K in 1 hours

= (1/2) + (1/3)

= (3 + 2)/6

= 5/6 parts

Required time = (6/5) hours

= 1 hours \(\frac{1}{5} \times 60\)

= 1 hour 12 minutes

∴ The pot will take 1 hour 12 minutes to filled.

Given:

Three pipes X, Y, Z can fill an overhead pot in 4, 6 and 12 hours respectively

Concept:

If a tap can fill a tank in x hours, then the tank filled by the tap in 1 hour = 1/x of the total tank.

Calculation:

Part of the pot filled by all three pipes in an hours

⇒ \(\frac{1}{4}{\rm{}} + {\rm{}}\frac{1}{6}{\rm{}} + {\rm{}}\frac{1}{{12}}{\rm{}} = {\rm{}}\frac{{6{\rm{\;}} + {\rm{\;}}4{\rm{\;}} + {\rm{\;}}2}}{{24}}{\rm{}} = {\rm{}}\frac{1}{2}\)

∴ The pot will be filled in 2 hours.

Correct option is B) fire place
