Let x be the angle then from the question 

angle = 5x complementary angle 

x = 5 (90 – x) => 6x = 450 

x = 75° 

The required angle is 75°.

Communication is the process of transmission of message, information, etc., and creation of understanding between two parties. It involves sending a message to another, who receives the message and responds to it. Effective communication takes place when the received message is understood in the same sense by the receiver as the sender intends. 

The barriers mentioned through the statements are: 

(a) Semantic barriers 

(b) Psychological barriers 

(c) Organisational barriers 

(d) Personal barriers

(a) Ashis is involved in controlling function of management. The benefits of such comparison of actual and standard output are : 

(i) It improves employee’s morale: Evaluation of performance against predetermined standard induces employees to do things in a proper manner. 

(ii) It help in better coordination: It keeps all activities and efforts directed towards the achievement of goals in conformity with the plans and programmes. 

(iii) It facilitates decision making: It helps to identify and solve problems before they become unmanageable. Timely decisions are taken, if anything needs rectification. 

(b) The values highlighted by Ashish are : 

(i) Motivating the workers

The concepts referred here are: 

(a) Liberalisation: ‘freed from unnecessary controls and restrictions’ 

(b) Privatisation: ‘greater role to private sector and reduced role to public sector’ 

(c) Globlisation: ‘integration of various economies of the world’ This change in the policy brought many changes. Two of them are: 

(a) All round competition/Increasing competition. Firm now face competition from Indian players (existing one as well as new entrants to the given industry). Competition from multinationals and from imports is the another facet of this new competitive environment. The easier access to better technology is an additional dimension. Finally, competitions will now be global in character, no more confined to the country’s boundaries. For example, Weston, a major player in the early days with over 18 per cent market share lost out heavily to competition from imported products. 

(b) Buyer’s market/More demanding customers. There were shortages practically in every sector-consumer goods, industrials goods and services. As a result, the buyers suffered. A shift from shortage to surplus has been a major development of the liberalized regime. Government removed controls on capacity creation and capacity utilization. Industry has been given total freedom to expand and diversify. Decisions on investments have been left on the entrepreneurs. Control on prices has been removed. Investment now takes place in areas of demand.

Archimedes principle states that when a body is immersed fully or partially in a fluid (liquid) it experiences an upward force that is equal to the weight of the fluid (liquid) displaced.

2 d = v × t
2 × 17.2 = 344 × 7
t = \(\frac { 34.4 }{ 344 }\) = 0.1 s

1 mole of CO₂ = 6.023 × 10²³ molecules
44 g = 6.023 × 10²³ molecules
Hence, 4.4 g = 6.023 × 10²² molecules

The ions which contains more than one atomic species in it are called polyatomic ions.
Example: SO^2-₄, Sulphate ion is a polyatomic ion.

For calculation Law of conservation of mass is used.

Two conditions that are need to be satisfied for work to be done:

• Force should act on the object, and
• The object must be displaced.

P = 60 W, t= 10 hours
E = P × t
= 60 × 10 = 600kWh
= 6.0 kWh
Bill to be paid =0.6 × 3.5 × 30 = ₹ 63

1. She was not in favour of western science and learning.

2. She hurt that there was no teaching about God and scriptures.

3. She was also not in favour of lessons in music. She thought it was not meant for decent and gentlefolk, but the monopoly of prostitutes and beggars.

Jute industry 

i. West Bengal is the home of jute. It produces the highest number of bales of the jute fiber. Adjoining regions of West Bengal, Bihar and Orissa are also important producers of jute. Thus, raw material is easily available. 

ii. Additional requirement of jute is met through import from Bangladesh. 

iii. Densely populated area of the lower Ganga basin provides cheap labour. 

iv. The industry consumes huge quantity of water which is easily available from the Hooghly River. 

v. Kolkata has a good network of transportation both of land and water. It has the facility of transport through rivers, canals, railways and roads. 

vi. International airport and a big port in Kolkata have also helped in the transportation of materials. 

vii. Coal-mines of Raniganj and Asansol provide sufficient supply of power to this industry in Kolkata.

“Asia has many places where people are few and few place where people are very many.”

(i) Cotton textile industry has three sub sectors i.e. handloom, power loom and mill sectors. Handloom sector is labour-intensive and provides employment to semi-skilled workers. 

(ii) This sector involves spinning, weaving and finishing of the fabric. The powerloom sector introduces machines and becomes less labour intensive and the volume of production increases. 

(iii) Cotton textile mill sector is highly capital intensive and produces fine clothes in bulk. It requires good quality cotton as raw material. India, China, USA, Pakistan, Uzbekistan and Egypt produce more than half of world’s raw cotton. 

(iv) The UK, North West European countries and Japan also produce cotton textile made from imported yam. Europe accounts for nearly half of the world’s cotton imports. This industry has to face very stiff competition with synthetic fibres, whether it has shown declining trend in many countries. 

(v) By scientific advancement and technological improvements the structure of industries changes. As—Germany recorded constant growth in this industry since World Ward I till 1970 but now it has declined.

Yes, because it results in the formation of two daughter cells, i.e., it results in the production of more individuals of the organism.

The total number of days for which the record is available = 250

(i) P(the forecast was correct on a given day)

 Number of days when the forecast was correct / Total number of days for which the record is available = 175/250=0.7

(ii) The number of days when the forecast was not correct = 250 - 175 = 75

So, P(the forecast was not correct on a given day)=75/250=0.3
