Answer:
a) - 72.5°c
b) pressure = 3625.13 Pa
c) density = 0.063 kg/m^3
d) it is a subsonic aircraft
Explanation:
a) Determine Temperature
Temperature at 19.5 km ( 19500 m )
T = -131 + ( 0.003 * altitude in meters )
= -131 + ( 0.003 * 19500 ) = - 72.5°c
b) Determine pressure and density at 19.5 km altitude
Given :
Po (atmospheric pressure at sea level ) = 101kpa
R ( gas constant of air ) = 0.287 KJ/Kgk
T = -72.5°c ≈ 200.5 k
pressure = 3625.13 Pa
hence density = 0.063 kg/m^3
attached below is the remaining part of the solution
C) determine if the aircraft is subsonic or super sonic
Velocity ( v ) = = = 283.8 m/s
hence it is a subsonic aircraft
Answer: Crustal Accretion or Crustal Generation
Explanation: These are the terms used to describe the process of new crust formation.
A one-dimensional motion can be plotted in a Cartesian plane. The Cartesian plane was first discovered by Rene Descartes. This is composed of four quadrants produced by the two intersecting axes, the x and y.
(1) Hence, the motion can be described using two directions, x and y.
(2) The symbol that should be used for the identification is (x, y).
