Answer:
<em>181 °C</em>
<em></em>
Explanation:
Initial pressure
= 100 kPa
Initial temperature
= 30 °C = 30 + 273 K = 303 K
Final pressure
= 1200 kPa
Final temperature
= ?
n = 1.2
For a polytropic process, we use the relationship
(
/
) = (
/
)^γ
where γ = (n-1)/n
γ = (1.2-1)/1.2 = 0.1667
substituting into the equation, we have
(
/303) = (1200/100)^0.1667
/303 = 12^0.1667
/303 = 1.513
= 300 x 1.513 = 453.9 K
==> 453.9 - 273 = 180.9 ≅ <em>181 °C</em>
“Rotation” refers to an objects spinning motion about it’s own axis.
“Revolution” refers to the objects orbital motion around another object.
Answer:

Explanation:
g = Acceleration due to gravity at sea level = 
R = Radius of Earth = 6371000 m
h = Altitude of observatory = 4205 m
Change in acceleration due to gravity due to change in altitude is given by

Weight at sea level

Weight at the given height

Change in weight 
Her weight reduces by
