The upper surface of tongue has four types of papillae: 

(i) Vallate or Circumvallate papillae: They are usually about 8-12 in number. Each vallate papilla contains upto 100 taste buds. These papillae are the largest of four types of papillae. 

(ii) Filliform papillae: They are smallest and most numerous of the four types. They are conical. They are found mainly near the centre and most of the upper surface of tongue. These papillae contain tactile (touch) receptors but not taste buds. 

(iii) Fungiform papillae: They are much less numerous than the filliform papillae. They are rounded but smaller than vallate but larger than filliform papillae. They are most numerous near the tip of tongue and contains fire taste buds. 

(iv) Foliate papillae: These are not well-developed in human tongue. These get degenerated in early childhood.

In Cross A because the genes are closely placed. Lesser the distance between genes greater is the strength of linkage.

Properties of scalar or dot products

(i) Dot product is commutative:- From definition, vector(A.B) = AB cosθ and vector(B.A) = BA cosθ = AB cosθ

Hence vector(A.B = B.A), which is commutative law.

(ii) Dot product is distributive over the addition of vectors:

i.e., vector{A.(B + C) = A.B + A.C}

(iii) Dot product of two parallel vectors:- The angle between two parallel vectors is zero,

i.e., θ = 0

Let vector vector(A + B) be two parallel vectors

Then vector(A.B) - AB cosθ = AB cos 0º = AB, (cos 0º = 1)

(iv) Dot product of two equal vectors:- The angle between two equal vectors is also zero

i.e., θ = 0, or cos 0º = 1

The dot product of two equal vectors is given by

vector(A.A) = AA cos0º = A²

Similarly, the dot product of unit vectors with itself is unity.

i.i = 1 x 1. cos0º = 1

j.j = 1.1. cos0º = 1

k.k = 1.1 cos0º = 1

Thus, i.i = j.j = k.k

(v) Dot product of perpendicular vectors:- The angle between two perpendicular vectors is 90º

i.e., θ = 90º or cos 90º = 0

If two vectors vector(A and B) are perpendicular, then

vector(A.B) = AB cos 90º = 0

Thus, two vectors are perpendicular if their dot product is zero.

Now i.j = 1 x 1 x cos 90º = 0

j.k = 1 x 1 x cos 90º = 0

k.i = 1 x 1 x cos 90º = 0

Thus, i.j = j.k = k.i = 0

(vi) Dot product of two anti-parallel vectors:- The angle between two anti-parallel vectors is 180º. i.e., θ = 180º or cos 180º = -1

If vectors vector(A and B) are anti-parallel vectors, then

vector(A.B) = AB cos 180º = -AB

(vii) Dot-product of two vectors in terms of their components:- The vectors vector(A and B) in terms of their components are written as:

vector A = A_xi + A_yj + A_zk and

vector B = B_xi + B_yj + B_zk

Hence, vector(A.B) = (A_xi + A_yj + A_zk).(B_xi + B_yj + B_zk)

= A_xB_x(i.i) + A_xB_y(i.j) + A_xB_z(j.k) + A_yB_x(j.i) + A_yB_y(j.j) + A_yB_z(j.k) + A_zB_x(k.i) + A_zB_y(k.j) + A_zB_z(k.k)

We know, i.i = j.j = k.k = 1

and, i.j = j.k = k.i = 0

Thus vector(A.B) = A_xB_x + A_yB_y + A_zB_z

1. The inter-particle space is very less in a wooden block. 

2. So we cannot compress it at ordinary conditions.

1. Sponge can be compressed.

2. It is a solid.

Justification :

1. The inter-particle space is slightly more than a rigid body. 

2. So that it can be compressed.

When pressure is applied and compressed the volume of a gas in a cylinder decreases. (According to Boyle’s law).

The call centre is a service framework, that is based on high-level communication and technology, in which a large number of telephone calls are handled, especially in one providing customer services function to a large organization.

(a) Entrepreneurship Programme

A call centre is a service framework, that is based on high-level communication and technology, in which a large number of telephone calls are handled, especially in one providing the customer services function to a large organization.

Functions of a Call centre: 

• Replying to customers against their queries. 
• Providing technical guidance to the customers of the company. 
• Registering a customer’s complaints. 
• Solving the problems of the customer.
• Giving customers a different type of information.

 Importance of call centres in Perspective of India: 

India is a developing country, where economic growth is achieved majorly through technical development. For the sale of products here, various companies have started using telemarketing, telebanking, television, and home shop facilities. Call centres are the mediators in between the organizations and the customers. They work and gap the bridge between the two.

In India, there are a large number of call centres and these organizations are serving the clients with utmost care and conviction. A call centre in India provides the best quality support and customer care services. The call centres are increasing employment opportunities among the youth at a vast level.

They are being designated as Call Centre Advisor, Team Leader, Call Centre Manager, Head of the Call Centre, Customer Services Director, Digital Contact Director, Operational Manager, Resource Planning Manager, Human Resources (HR) Trainer, etc. Today, many call centres are operating in India in Delhi, Gurgaon, Bengaluru, and Hyderabad in order to perform various tasks. They deal with customers’ queries and help them to get the best information.

Technical help desk service is also provided to them, as they deal with the technical issues of the customers and the agents try to troubleshoot their problems and show them the right way. Indian call centres have been successful on an extensive level since the level of English language proficiency in Indian youth is good and their pronunciation is also very good and acceptable at the international level.

• Increase in foreign exchange. 
• Helps in removing unemployment.
