Q1. What is turbo charger
Ans. 
A turbocharger is a device that increases the efficiency and power output of an engine by compressing the air intake.
• Turbochargers use exhaust gases to spin a turbine, which in turn drives a compressor to increase the air intake pressure.

• This allows more air to be forced into the engine, resulting in more fuel being burned and more power being produced.

• Turbochargers are commonly used in high-performance cars and diesel...read more

Q3. What the least count of vernier calliper
Ans. 
The least count of vernier calliper is the smallest measurement that can be read on the scale.
• The least count is determined by the number of divisions on the vernier scale and the main scale.

• It is usually 0.1 mm or 0.02 mm for a metric vernier calliper and 0.001 inch for an imperial vernier calliper.

• To determine the least count, subtract the value of one main scale division from the value of one vernier scale division.
