A Physics teacher is explaining the difference between average speed and average velocity to her students. Where average velocity = ("displacement")/("time taken") , "average speed" = ("actual distance travelled")/("time taken") She emphasises that average speed is more relevant than average velocity, because displacement from one place to other is only theoretical, being the shortest distance between two places. Average speed is the real entity that matters, taking into account the actual time taken to travel the actual distance between the two stations. Read the above passage and answer the following question : (i) Do you agree with the statement of Physics teacher ? (ii) The shortest distance between Ambala to Delhi is 200 km . A train takes 4 hrs and covers a distance of 210 km in going from Ambala to Delhi via Karnal. Another train takes 5 hrs and covers 250 km distance in going from Ambala to Delhi via Saharanpur. What is the average speed of these two trains? What would be the average velocity of a train that takes 2.5 hrs to cover 200 km distance ? (iii) What values do you learn from this discussion ?

Two independent monohybrid crosses were carried out involving a tall pea plant with a dwarf pea plant. In the first cross, the offspring population had equal number of tall and dwarf plants, whereas in the second cross it wad different. Work out he crosses, and explain giving reason for the difference in the offspring populations.

Rahul decided to start a desert cooler manufacturing business. He sets the target of earning 20% profit on sales in the first year. He was very much concerned about the future prospects of the business, which were uncertain. For this, he gathered information from the potential market and analysed that the demand for wall-mounted coolers is increasing day by day. He used this information as the base for future planning. On the basis of the gathered information, he called a meeting in the following week to find new methods to achieve the objective. (a) Idnetify the function of management involved in the above case. (b) Enumerate the next two steps, which have been followed by Rahul that are related to the process of one of the functions of management.
