Titan's exosphere has a temperature of about 172 k. what is the thermal speed of hydrogen (in km/s) in titan''s exosphere? the mass of a hydrogen atom is 1.67 × 10-27 kg and boltzmann's constant is k = 1.38 × 10-23 joule/kelvin.

Thermal speed, v = 2.064 km/s

Explanation:

It is given that,

Temperature of Titan's exosphere, T = 172 K

Mass of the hydrogen atom,

Boltzmann's constant,

Let v is the thermal speed of Hydrogen. It can be calculated using the following formula as :

v = 2064.93 m/s

or

v = 2.064 km/s

Hence, the thermal speed of hydrogen in Titan's exosphere is 2.064 km/s.

the only other powers were germany russia and uk and they were too busy fighting each other wearing each other down   that the us was becoming strong and they were becoming weaker
