In which of the following situations, does the list of numbers involved make an arithmetic progression, and why? (i) The taxi fare after each km when the fare is Rs 15 for the first km and Rs 8 for each additional km. (ii) The amount of air present in a cylinder when a vacuum pump removes 1/4 of the air remaining in the cylinder at a time. (iii) The cost of digging a well after every metre of digging, when it costs Rs.150 for the first metre and rises by Rs. 50 for each subsequent metre. (iv) The amount of money in the account every year, when 10000 is deposited at compound interest at 8 % per annum.

In which of the following situations, does the list of numbers involved make arithmetic progression, and why ? (i) The taxi fare after each km when the fare is 15 Rs for the first km and Rs. 8 for each additional km. (ii) The amount of air present in a cylinder when a vacuum pump removes 1/2 of the air remaining in the cylinder at a time.

the presseure inside th receiver of an air pump is reduced to 1/4 of the initial pressure after 3 strokes. What will be the pressure after 8 strokes ?

Carbon monoxide emitted by automobiles is an environmental hazard . A car has an engine of four cylinders with a total cylinder volume of 1600 cc and a fuel consumption fo 7.0 dm^(3) per 100 Km , when driving at an average speed of 80 km/hr . In one second , each cylinder goes through 25 burn cycles and consumes 0.400g of fuel . The compression ratio, which is the ratio between the smallest and largest volume within the cylinder as the piston moves forward and backward is 1:8. Calculate the air intake of the engine (m^(3)S^(-1)) , if the gaseous fuel and air are introduced into the cylinder when its volume is largest until the pressure is 101.0 KPa. the temperature of both incoming air and fuel is 100^(@) C. (Assume the fuel to be isoctane , C_(8)H_(18))

In the figure, an air lens is cut a cylinder of glass of refractive index 1.5 . The nature of the lens is
