As an aircraft flies 500 miles, from a region of higher pressure into a region of lower pressure, with the aircraft’s pressure altimeter indicating a constant altitude of 700 feet, is the aircraft’s actual altitude changing? if so, is it gaining or losing altitude? explain your answer. (assume constant temperature air and no corrections made to the altimeter along the flight path.)

Aircraft is losing altitude

Explanation:

= Density of air

P = Pressure

g = Acceleration due to gravity = 9.81 m/s²

h = Altitude

1 denotes initial

2 denotes final

From Bernoulli's theorem we have

Velocity v is constant

From the question

so in the equation

So, the aircraft is losing altitude

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the sun.jul 26, 2018

explanation:

real, smaller and upside-down.   so the answer should be b.
