Reflection from a moving mirror produces a Doppler shift, and thus the momentum delivered to the front and rear walls can easily be calculated in the laboratory frame. A simple application of F=ma leads to the usual conclusion that the mass of a gas of photons of total energy U is U/c...
Using Einstein's mass-energy formula,constituting the radiation in a cavity,contribute to the gas of massless photons.This radiation energy hypothesis U. A simple application of calculations in the co- accelerating frame. leads to the usual conclusion that the mass of a gas of photons of total...
To find the relative molecular mass (molar mass) of the gas given that 5.6 liters of it at STP has a mass of 12 grams, we can follow these steps:1. Understand the Relationship at STP: At Standard Temperature and Pressure (ST
【一】‘the lower... the faster...’ 是指‘...越低，...就越快’。【二】 the molecular mass of gas 意思是气体分子量；it will diffuse 是指它将扩散。【总结】气体分子量越低（就是越少），它扩散的速度就越快。希望对你有帮助哦。。。```*/\*```...
Average mass ratios of the gas-to-dust are thus found to be 100 or 450. Detailed comparison of the CS and IRAS images reveals, however, that average values are rarely, if ever, found on local scales on the order of 0.15pc. 展开 ...
According to this law, the pressure of a given mass of gas at constant temperature is in inverse proportion to the volume occupied by the gas. A. 根据这个定律,在恒定温度下,某定量气体的压力和该气体的体积成反比。 B. 根据这个定律,在恒定温度下,某定量气体的压力和该气体的体积成正比。 C. ...
19The volume, V, of a given mass of gas, is inversely proportional to the pressure, P.(a)Sketch a volume-pressure graph for the mass of gas.Answer (a) V P[1]When the volume is 3 m3, the pressure of the gas is 200 N/m2.(b)Find the equation for Vin terms of P.Answer (b...
Define centers of mass. centers of mass synonyms, centers of mass pronunciation, centers of mass translation, English dictionary definition of centers of mass. n. pl. centers of mass Abbr. CM The point in a system of bodies or an extended body at which t
However, this procedure has uncertainties associated with the unknown distribution of the gas clouds. Here, we show that the black hole masses derived from the properties of the accretion disk and virial mass estimates differ by a factor that is inversely proportional to the width of the broad ...
