relative humidity- the ratio of the amount of water in the air at a give temperature to the maximum amount it could hold at that temperature; expressed as a percentage ratio- the relative magnitudes of two quantities (usually expressed as a quotient) ...
When the determination is madeby weighing, the buoyancy of air is disregarded, which mayintroduce an error of 1 unit in the 3rddecimal place. Whenusing a density meter, the buoyancy of air has no influence.Oscillating transducer density meter. The apparatus consistsof:— a U-shaped tube, ...

The word 'humidity' refers to how much water vapor is in the air. 'Relative humidity' is reported as a percentage that tells how close the air is to being saturated with water vapor. At 100% relatively humidity, the air is completely saturated with water vapor....
The insulator is assumed to be air, with relative permittivity ɛ = 1. The metal is silver, whose complex relative permittivity ɛsilver is represented by the Drude model: (102)ɛsilver(ω)=ɛ∞−ωpω(ω+iΓ), where the bulk plasma frequency ωp = 1.38 × 1016 rad/s, the...
Homework Statement So I am in an elevator throwing a ball in an air, straight up and down, about 1 meter from my hand. The elevator is moving upwards at a rate of 2 m/s. From an observer on the ground, would they see the ball reach its peak at the same instant that I do? If...
