A good store layout helps customers to find and purchasemerchandise.The grid design is best for stores in which customers are expectedto explore the entire store, such as grocery stores and drugstores. Racetrack designs aremore common in large upscale stores like department stores. Free-form designs areusually found in small specialty stores and within large stores' departments.

The principles of visual merchandising are: 

• Make it easier for the customer to locate the desired category and merchandise. 
• Make it easier for the customer to self-select. 
• Make it possible for the shopper to co-ordinate and accessorize.

Clearly, 3/5 = 0.6, 4/7 = 0.571, 8/9 = 0.88, 9/111 = 0.818. 

Now, 0.88 > 0.818 > 0.6 > 0.571 

8/9 > 9/11 > 3/4 > 13/ 16

Converting each of the given fractions into decimal form, we get : 

5/8 = 0.624, 7/12 = 0.8125, 16/29 = 0.5517, and 3/4 = 0.75 

Now, 0.5517 < 0.5833 < 0.625 < 0.75 < 0.8125 

16/29 < 7/12 < 5/8 < 3/4 < 13/16

Given:

11/17, 41/63, 3/7, 21/29

Concept used:

If we make the denominator of all fractions equals then the greater numerator will greater fraction and vice versa.

Calculation:

For the equal denominator, 

LCM of denominators = 31059

11/17 = (11 × 1827)/(17 × 1827) = 20097/31059

41/63 = (41 × 493)/63 × 493) = 20213/31059

3/7 = (3 × 4437)/(7 × 4437) = 13311/31059

21/29 = (21 × 1071)/(29 × 1071) = 22491/31059

clearly we can see that,

3/7 < 11/17 < 41/63 < 21/29

∴ 3/7 < 11/17 < 41/63 < 21/29.

Graphite allotrope of carbon is used as a solid lubricant 

Correct option is B) was speaking

\(2NH_3 (g) \rightleftharpoons N_2(g) + 3H_2(g)\)

as we know 

\(K_p = K_c (RT)^{\Delta n}\)      ....(i)

\(\Delta n\) for above reaction = (1 + 3) - 2 = 2

\(K_p = K_c (RT)^2\)       .....(ii)

and 

\(K_p = \frac{P_{N_2}\times P^3_{H_2}}{P^2_{NH_3}}\)          ....(iii)

Using equation (ii) & (iii)

\(K_c(RT)^2 = \frac{P_{N_2}\times P^{3}_{H_2}}{P^2_{NH_3}}\)

\(K_c = \left(\frac{P_{N_2} \times P^3_{H_2}}{P^2_{NH_3}}\right)\times \frac1 {(RT)^2}\)

Correct option is A) is / speaking

Correct option is A) Are

Correct option is C) was

Atomic size of oxygen is smaller. It can form σ– bond as well as  π– bond between O and O atoms and exists as O₂.

Atomic size of sulphur is bigger. It can not form π – bond together with s – bond between S and S atoms. To satisfied its valency, it forms S₈ molecule in which all atoms of sulphur bonded with only σ– bond . 

There are three main ways of grouping. 

a. Series grouping. 

b. Parallel grouping. 

c. Series-parallel grouping

Electrolyte is the medium through which the current produces chemical changes. Electrolyte is a mixture of sulphuric acid o 1.85 specific gravity (concentrated sulphuric acid) diluted with distilled water in the ratio of 1:3 approximately, so the specific gravity of the dilute sulphuric acid is 1.280. 

Negative plates are one more than positive plates so as to get negative plates on both the sides of positive plates. This is to prevent the buckling action of the lead on positive plate in the multi plate lead acid cell. The other reason is that both the sides of positive plates will become active and the efficiency of the positive plate and the cell will increase. 

The negative plate of a lead acid cell is made up of spongy lead ‘Pb’. The negative plates are also of rectangular lead grid and the active material Pb in the form of paste is held firmly in this lead grid. 

There are two types of positive plate preparation. They are Plante plate and Faure plate.

Plante plate.

As per plante process positive plate PbO₂ are prepared by a process of repeated charging and discharging of pure lead. Positive plates, which are made by this process, are also called ‘formal plates’. This process of positive plate preparation required very long time for it’s manufacturing and so it is very costly.

Faure plate.

Faure plates are generally made up of rectangular lead grid into which the active material lead peroxide PbO₂ is filled in the form of paste.

The correct answer is Bleaching powder.

• Calcium hypochlorite is an inorganic compound with the chemical formula Ca(OCl)₂.

• It is commonly referred to as bleaching powder or calcium oxychloride.
• It is produced industrially by treating lime (Ca(OH)₂) with chlorine gas.
• It is very stable and can be stored for an extended period of time.
• This compound is the main ingredient of commercial products such as bleaching powder, chlorine powder and chlorinated lime which are used for water treatment and as a bleaching agent.
• It is also used in the sanitization of public swimming pools and to disinfect drinking water.

In AC single-phase motors speed control can not be achieve as smooth as in DC motor. There are following few methods of speed control.

b. By changing the applied voltage to the stator. 

c. Frequency control method. 

d. Rotor rheostat control. 

e. By operating two motors in concatenation or cascade or tandem method. 

f. By injecting an emf in the rotor circuit. 

g. By changing slip.
