Answer:
-13° C
Explanation:
Data provided:
The temperature of the air at sea level = 26° C
The height at which temperature is to be calculated = 6000 m = 6 Km
Now,
Using the average lapse rate
Here,
is the temperature at the height 'h' above the mean sea level
is the temperature at the mean sea level
is the average lapse rate = 6.5° C per Km
h is the height above mean sea level at which the temperature is to be calculated in Km
on susbtituting the respective values in the above formula, we get
= 26° C - ( 6.5 × 6 )
or
= 26° C - 39° C
or
= -13° C
the answer to this question is b because i just took the test
Answer:
D. Hertzsprung-Russell Diagram
Explanation:
The Hertzspring-Russel Diagram or HR-Diagram is used to study the evolution of stars. It plots stars depending on the temperature against luminosity. Stars go through different changes depending on its mass at the beginning. These changes occurs in stages and each stage is marked by a change in temperature and luminosity.
