## Physics Water boils at a lower temperature on the hills because

It is cold on the hills
There is less carbon dioxide on the hills
There is a decrease in air pressure on the hills
There is less oxygen

## Physics Of the four locations mentioned below the highest inside temperature will be attained in the pressure cooker operated with the pressure valve open

at the top of Mt. Everest
at a place in a valley below sea level
in an aeroplane flying at a height of 10,000 m with inside pressure maintained at the sea level
at sea level

## Physics Which of the following pairs of physical quantities have the same dimensions?

Work and Power
Momentum and Power
Force and Power
Work and Energy

## Physics Hydraulic brakes work on the principle of

Bernoulli's theorem
Pascal's law
Newton's law
Thomson's law

## Physics Lightning is produced when

Water vapour produces electricity in the clouds
Similar charges of electricity rush towards each other and then get repelled
Strong opposite charges in different clouds break down the resistance offered by the intervening air
Clouds strike against impurities in air and the friction burns up these impurities
