reply above post

temperatur changed from 16 to -4 as we go up the cliff
so for every 1m rise change in temperature is 20/3000 = 1/150 C
for 1800m rise change will be 1800 x 1/150 12 C so new temperature = 16-12=4C

ii) when temperature is 0 C it means temp fall by 16 C
so X x 1/150 = 16
X = 0150 x 16 = 2400 m

iii) it is sort of finding the equation ...
cordinate = (3000,-4) (0,16)

eq will be 150y = 2400 - x
and so 150T = 2400 - x

moni
@::A^
(12)^0.5 ko yun b likh saktay hai (2 x 2 x 3) ^0.5 thus 2 ka ek pair hai to take 2 out ull get 2(3)^0.5
3^3/2 = 27^0.5 = (3 x 3 x 3)^0.5 yaha b 3 ka ek pair ban raha hai to take 3 out it will become 3(3)^0.5

now 3^0.5 are cancelled leaving 2/3

tumhe ye tab he samajh aega if you know how to take out numbers from square roots
