Question

A certain fortin barometer has it's pointers , body and scales made from brass. when it is at 0 degree sentigrate it records a barometric pressure of 760 hg mm of Hg. what will it read when its temprature is increased to 20 degree sentigrate if the pressure of the atmosphere remains uncharged ? [ cubic expansivity of mercury (Y)=1.8*10^-4 k^-1, Linear expansivity of brash (alpha)= 2*10^-5 K^-1]

Ok sure

Yeah me from Uttarakhand
Almost always​

Answer 1

Uttarakhand, a state in northern India crossed by the Himalayas, is known for its Hindu pilgrimage sites. Rishikesh, a major centre for yoga study, was made famous by the Beatles’ 1968 visit. The city hosts the evening Ganga Aarti, a spiritual gathering on the sacred Ganges River. The state's forested Jim Corbett National Park shelters Bengal tigers and other native wildlife.
