A farmer traditionally irrigates fields manually (labour-intensive). He installs drip irrigation (a technology upgrade) that reduces water use by 40% and increases yield by 30%. How does this affect a) His cost of production b) His willingness to supply at different prices c) The overall market supply if many farmers adopt this technology
His cost of production decreases because efficient drip irrigation reduces labor and water expenses while boosting agricultural yield. Lower costs improve profit margins, increasing his willingness to supply larger quantities across different price levels. If multiple farmers adopt this technology,Read more
His cost of production decreases because efficient drip irrigation reduces labor and water expenses while boosting agricultural yield. Lower costs improve profit margins, increasing his willingness to supply larger quantities across different price levels. If multiple farmers adopt this technology, aggregate production grows significantly, shifting the overall market supply curve outward and expanding availability across the entire marketplace.

The correct choice is option b) Shortage. When the government imposes a price ceiling below the market equilibrium price, it makes the essential vaccine highly affordable, which sharply increases the quantity demanded by the public. However, the artificially lowered price reduces profits for pharmacRead more
The correct choice is option b) Shortage. When the government imposes a price ceiling below the market equilibrium price, it makes the essential vaccine highly affordable, which sharply increases the quantity demanded by the public. However, the artificially lowered price reduces profits for pharmaceutical producers, causing them to supply less. This disparity between high demand and low supply inevitably creates a market shortage.

See lessDuring online festival sales, the prices of many products are very low. Use the concept of demand and supply to explain why the sellers sell at such a low price. What happens to the equilibrium when the price is lowered? Does this benefit only consumers or sellers as well? Explain.
Sellers reduce prices during festival seasons because the law of demand dictates that lower prices attract massive customer volumes. Lowering prices creates high demand, shifting the market toward a higher equilibrium sales quantity. This arrangement benefits consumers through substantial savings anRead more
Sellers reduce prices during festival seasons because the law of demand dictates that lower prices attract massive customer volumes. Lowering prices creates high demand, shifting the market toward a higher equilibrium sales quantity. This arrangement benefits consumers through substantial savings and benefits sellers by allowing them to clear large inventories, attract new buyers and maximize overall revenue through bulk turnover.

See lessWhile practising for the snake boat race (Vallum kalli in Kerala), 100 oarsmen are rowing a boat together. Out of these, 95 row backwards to propel the boat forward. But by mistake, 5 oarsmen row in the opposite direction. If each oarsman applies a horizontal force of 200 N, what is the net force on the snake boat? (Ignore drag forces, air friction, etc.)
Each oarsman exerts a horizontal force of 200 N. The 95 oarsmen rowing to push the boat forward provide 95 multiplied by 200 N, equaling 19000 N forward force. The 5 oarsmen rowing backward provide 5 multiplied by 200 N, equaling 1000 N opposing force. The resulting net force on the snake boat is 19Read more

The 5 oarsmen rowing backward provide 5 multiplied by 200 N, equaling 1000 N opposing force. The resulting net force on the snake boat is 19000 N minus 1000 N, which equals 18000 N in the forward direction.

See lessTwo blocks P and Q on a smooth horizontal surface are shown in Fig. 6.36a and Fig. 6.36b. Two forces of magnitudes 4 N and 5 N are acting in opposite directions on block P, while block Q is moving with a constant velocity. Which of the following statement is correct? (i) P experiences a net force and Q does not experience a net force. (ii) P does not experience a net force and Q experiences a net force. (iii) Both P and Q experience a net force. (iv) Neither P nor Q experiences a net force.
Option (i) is the correct statement. Block P is acted upon by two unequal opposing forces of 5 N and 4 N, resulting in an unbalanced net force of 1 N to the right. Block Q travels at a constant velocity with zero acceleration, which according to Newton first law of motion indicates that the net exteRead more
