Answer:
Read this excerpt from Robert Stawell Ball’s Great Astronomers: Though every child may now know more of the actual truths of the celestial motions than ever Ptolemy knew, yet the fact that his work exercised such an astonishing effect on the human intellect for some sixty generations, shows that it must have been an extraordinary production. We must look into the career of this wonderful man to discover wherein lay the secret of that marvellous success which made him the unchallenged instructor of the human race for such a protracted period. Based on the context of the excerpt, what does the word protracted most clearly mean? seeming to be truthful weighing an excessive amount extending in a specific direction continuing for a long time being exceptional or talented
Answer:
Social and emotional experiences change with age. Social partners that are meaningful and important are preserved, more peripheral social ties are discarded, and anger and distress are experienced less frequently. Positive affect remains highly stable, only decreasing in some studies among the oldest old.
Oligopoly is a market structure of few sellers, where few firms dominate the whole market. Sellers are the main supplier and gain all the output of market. Now let us see what are the elements which enable the oligopoly.
Large investment capital:
A new entry is a ban in oligopoly structure because of very heavy investment. A new entry may have fear of cost maintenance because of established firms because it is true that in midst of product it is difficult to make a new product.
Absolute cost advantage:
Small firms always have an absolute cost advantage on raw material, training, techniques, natural resources, economic resources, where new entrants cannot survive and small firms earn a profit even in low price.
Small firms have strong marketing chain and network. As new entry comes, they compete them out through different strategies.
Product differentiation:
Small firms get an advantage of product differentiation. Buyers develop the loyalty to the brand so for new entry it is very difficult to compete for a brand and gain customer loyalty until unless they make any superior thing than that brand.
Mergers:
Modern businesses now have learned to merge to eliminate competition.
Doing this, the number of firms decline, profit increases and oligopolies are established.
Informal collusion:
Mergers are formed but mergers have some constitutional complexities. So to avoid the law complications most firms have informal agreements between them to earn the profit and get rid of law bindings.
Answer:
flexible; an adolescent.
Explanation:
Cognitive development can be defined as the development of thought processes, skills, knowledge and problem-solving abilities from infancy through adulthood.
Jean Piaget was a developmental biologist and psychologist who worked extensively on cognitive development in infants and teenagers; these are judgement, knowledge and thoughts.
Jean Piaget's stages of cognitive development in an ascending order are;
I. Sensorimotor: this is between 0 - 2 years (18 - 24 months) where the child exhibits object permanence.
II. Preoperational: this is age 2 - 7 years where the child acts in an egocentric manner.
III. Concrete operational: this is age 7 through age 11 and the child thinks logically at this stage.
IV. Formal operational: this is from adolescence (11 years) through adulthood and focuses on logically thinking about abstractions.
In this scenario, Todd's cognition is probably more practical, more flexible, more likely to coordinate intuitive and analytic thought than when Todd was an adolescent due to his being young at heart.
