According to Wookieepedia, Kylo Ren stands 1.89 m tall and his mass is 89 kg. Calculate his earth-weight in lbm. (2 pts) a. b. A

harina [27]

Answer:

a) 6312.12 lbm

b) D = 11.843 inch

Explanation:

GIVEN DATA:

Height of person = 1.89 m = 74.41 inch

mass of person m = 89 kg = 196.211 lbm

a) person earth weight =mg

where g is acceleration due to gravity = 32.17 ft/sec^2

$= 196.211\times 32.17 = 6312.12 lbm$

b) waist to height ratio = 0.5

$waist\ to\ height\ ratio = \frac{circumference\ of\ the\ waist}{height\ of\ the\ person}$

circumference of waist = $height\ of\ person \times waist\ to\ height ratio$

$= 74.41 inch \times 0.5$

=37.21 inch

we know that circumference is given as $= 2\pi r\ or\ \pi D= 37.21$

D = 11.843 inch

Assoli18 [71]

<u>Answer:</u> The value of $K_p$ for the chemical equation is $8.341\times 10^{-5}$

<u>Explanation:</u>

For the given chemical equation:

$N_2(g)+O_2(g)\rightarrow 2NO(g)$

To calculate the $K_p$ for given value of Gibbs free energy, we use the relation:

$\Delta G=-RT\ln K_p$

where,

$\Delta G$ = Gibbs free energy = 78 kJ/mol = 78000 J/mol (Conversion factor: 1kJ = 1000J)

R = Gas constant = $8.314J/K mol$

T = temperature = 1000 K

$K_p$ = equilibrium constant in terms of partial pressure = ?

Putting values in above equation, we get:

$78000J/mol=-(8.314J/Kmol)\times 1000K\times \ln K_p\\\\Kp=8.341\times 10^{-5}$

Hence, the value of $K_p$ for the chemical equation is $8.341\times 10^{-5}$
