State two limitations of Maslow’s Theory of the hierarchy of human needs.

Answer»

Recent research challenges the order that the needs are imposed by Mas low’s pyramid. As an example, in some cultures, social needs are placed more fundamentally than any others. Further, Mas low’s hierarchy fails to explain the “starving artist” scenario, in which the aesthetic neglects their physical needs to pursuit of aesthetic or spiritual goals. Little evidence suggests that people satisfy exclusively one motivating need at a time, other than situations where needs conflict.

‘Transfer is a mild form of punishment’. Explain.

Answer»

Transfer is a mild form of punishment. It is true. When the employee neglects work or conflicts with other employees or does the act of misconduct, the management can transfer the erring employee to a new place. Transfer from one place to another (unimportant place) is a very common practice while punishing the employees.

An ideal inductor does not consume any power even though both V and I are non zero. Explain in brief.

Answer»

The power consumed in an ac circuit is given by 

Pa = EvIv cos Φ where Φ is the phase difference between E and I

For an inductor Φ = 90°

∴ cos Φ = 0

∴ Pa = Ev x Iv x 0 =0

∴ An inductor consumes no power.

(ii) Power : Regular supply of power is a prerequisite for the localization of industries. Tata Iron and Steel Company at Jamshedpur, Aluminium Plant at Korba in Chhattisgarh and Renukoot in U.P., Copper smelting plant at Khetri, Rajasthan are near the sources of power and raw material.

(iii) Transport: Transport by land or water is necessary for the assembly of raw materials and for the marketing of finished products. The location of many industries around Kolkata, Mumbai and Chennai is due to the development of railways in India, connecting the port towns with their hinterlands.

(b) (i) Industries tend to be concentrated in a few pockets because of certain favorable factors. The pockets having high concentration of industries are known as industrial clusters.

(ii) Gurgaon-Delhi – Meerut industrial region. Two reasons for its growth are :

1. It owes its development and growth to hydro-electricity from Bhakra-Nangal complex and thermal power from Harduaganj, Faridabad and Panipat.

2. It is one of the fastest-growing market-oriented industrial cluster adjoining Delhi.

An array AR [-4…. 6, -2 ….. 12 ], stores elements in Row Major Wise, with the address AR[2] [3] as 4142 . If each element requires 2 bytes of storage, find the Base address.

Answer»

AR [-4,… 6, -2 … 12]

Row- wise order, 

AR[2] [3] = B + W(n(i-1)+(j-1)) 

Given i = 2, j = 3, W = 2 bytes 

B = ? 

n = Uc – Lc + 1 

= 12 – (-2) + 1 

= 12 + 2 + 1 

= 15 Now, 414 

= B + 2 [15 (2 -(-2)) + (3-(-4))] 

B + 2[60 + 7] 

= 4142 B + 134 

= 4142 or B = 4008

Sometimes we need to iterate the loop before it finishes all the statements inside a loop then we use continue statement and jump to the next iteration of a loop.

4545.

Why is class known as composite data type ?

Answer»

The class is known as composite/flata type because a composite or reference data type are the data elements whose value is an address. The values in a composite data type cannot be assigned directly. It is assigned with the help of a reference. For example, if there are two public integer variables in class XYZ as A and B then the value to those variables cannot be assigned directly. 

They can be assigned with the help of the following reference:

XYZ obj1; //creating an object of XYZ class 

Obj1.A=10; //referencing the variable. 

Obj1.B=20; 

Thus class is a composite data type because it requires a reference to use its attributes.
