Atmospheric pressure is the force per unit area exerted on a surface by the weight of air above that surface in the atmosphere of Earth. Atmospheric pressure is measured with an instrument called a "barometer", which is why atmospheric pressure is also referred to as barometric pressure.

Solve: If a^2+b^2=52 and ab=24, find the value of (a-b)?
Take, (a-b)^2=a^2-2ab+b^2 we know that a^2+b^2=52 and ab=24 Substituting in the above equation, we get (a-b)^2=52-2*24 (a-b)^2=4 or (a-b)=sqrt of 4 Hence, (a-b) = 2
