The density of matter (primarily hydrogen atoms) in intergalactic space is such that its contribution to the pressure is of the order of 23 a) what is the approtinate density of mate in amm') in intergalactic approximate density of matter (in atoms/m3) in intergalactic space? b) what is the ratio of the kinetic energy of matter to the energy of radiation in intergalactic space? (recall problems 3.6-1 and 3.6-2.) c) what is the ratio of the total matter energy (i. e., the sum of the kinetic energy plus the relativistic energy mc2) to the energy of radiation in intergalactic space?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
