Answers
Answer:
Ans .1) Speedometer – The speedometer is a gauge that indicates the current speed the vehicle is traveling.(the one which showed reading approx 50 km/h).
Tachometer – The tachometer’s job is to display the speed of the engine in revolutions per minute or RPMs. Because transmissions have many gears, the speed of the car does not match engine speed and transmission gears are designed to convert the speed of the engine into acceleration and performance (the one with very high reading).
Ans .2) In order to prevent any accident from happening as in mountains there are turns everywhere, the vehicle can skid or slip if the speed limit is not followed.
Ans .3) Raman is a very curious boy who wants to learn more about the scientific world. He also displays the quality of a good and responsible citizen.
