Answer:
scale height = 19.80 km
Explanation:
given data
earth scale height = 8.6 km
atmospheric pressure = 10%
to find out
scale height
solution
we know that with the scale height we can find value of physical parameter that is change with height
and height is that value of pressure or density th of ground value
so we can say
= 10%
= 0.1
take log both side
t log(0.3678) = log 0.1
t = 2.3025
so
scale height for 10% is
scale height = 2.3025 × 8.6
scale height = 19.80 km
