Except when necessary for takeoff and landing, <span>the minimum safe altitude required for a pilot to operate an aircraft over other than congested area is an altitude of 1000 ft above the highest obstacle within a 2000 ft horizontal radius of the aircraft.
It is also good to know that apart from taking off and landing, the aircraft must not operate at a distance less than 500 ft from any person, vessel, structure or vehicle.</span>
Answer:
Sun
Explanation:
Sun Can Give Us Light Energy And It convert Into Heat Energy
Answer: 
Explanation:
We know the total diameter of the cell (assumed spherical) is:
Then its total radius 
On the other hand, we know the thickness of the cell wall is 
and its density is the same as water (
).
Since density is the relation between the mass 
and the volume 
:
The mass is: 
(1)
Now if we are talking about this cell as a thin spherical shell, its volume will be:
(2)
Where 
Then:
(3)
(4)
Substituting (4) in (1):
(5)
(6)
Knowing 
and 
:
Answer:
The objects kinetic energy increases as it falls from some height.
The answer would be flood basalt. This is the outcome
of a huge volcanic eruption or sequence of eruptions that covers large expanses
of land or the ocean floor with basalt lava. The development and
effects of a flood basalt hinge on a variety of factors, like latitude, continental
configuration, rate, volume, period of eruption, the preexisting climate
state, style and location, and the biota flexibility to alteration.
