Answer:
a) 3170 kw
b) 377 km^2
Explanation:
Estimate of electric power
a) Given :
Average power consumption for a family of 3 = 108.4 * 106 BTU per year = 0.0317 kw = 31.7 watts
<u>The power requirement for a city of 300000 people </u>
= 31.7 watts * 100000 = 3170000 watts = 3170 kw
b) Given :
Average solar panel insulation = 8.4 W /m^2
<u>Estimate the area of silicon solar cells required to satisfy community power requirement</u>
= (1 * 3170) * (1000/8.4 )
= 377.380 * 10^3 m2 = 377 km^2

Answer:
Option b, pothographs from drones.
Explanation:
the USGS (U.S. Geological Survey) decided to make photographic captures from drones to the volcanic surfaces, which allowed through observations to understand things like the characteristics of the lava, the height of the volcanic plumes (among others).

The instrument used to measure atmospheric pressure is called a Barometer.
