A. By ensuring they follow the scientific method
Condensation endothermic or exotérmica
Answer:
h = 48.077 ft
Explanation:
given,
distance between two observer = 300 ft
angle of elevation to top pole = 16° and 20°
height of the flagpole = ?
now,
Let h be the height of the flagpole
Let x be the distance of the pole
![tan 16^0 = \dfrac{h}{x}](https://tex.z-dn.net/?f=tan%2016%5E0%20%3D%20%5Cdfrac%7Bh%7D%7Bx%7D)
![x =\dfrac{h}{tan 16^0}](https://tex.z-dn.net/?f=x%20%3D%5Cdfrac%7Bh%7D%7Btan%2016%5E0%7D)
now,
again applying
![tan 20^0 = \dfrac{h}{300-x}](https://tex.z-dn.net/?f=tan%2020%5E0%20%3D%20%5Cdfrac%7Bh%7D%7B300-x%7D)
![300-x=\dfrac{h}{tan 20^0}](https://tex.z-dn.net/?f=300-x%3D%5Cdfrac%7Bh%7D%7Btan%2020%5E0%7D)
![300-3.49 h=2.75 h](https://tex.z-dn.net/?f=300-3.49%20h%3D2.75%20h)
![6.24h = 300](https://tex.z-dn.net/?f=6.24h%20%3D%20300)
h = 48.077 ft
Answer: A forest fire could affect the geosphere by ash and the heat from the fire, but the fire would affect the biosphere by less oxygen in the air and would make it hard for human to breath affecting climate change. Also many homes to wildlife that live in the forest would lose their homes. This would result in lose of money from no hunting and that affect the economy.
