Answer:

The pressure altitude is A =  10\ km

The density altitude is \rho = 0.429 kg/m^3

Explanation:

From the question we are told that

The outside pressure is P_o  =  2.65*10^{4} N/m^2

The outside temperature is T_o =  215 \  K

Generally the density altitude is mathematically represented as

\rho =  \frac{P_o }{RT}

Here R is the gas constant with value R =  287\  J/kg/K

So

\rho =  \frac{2.65 (*10^{4}}{287 * 215}

=> \rho = 0.429 kg/m^3

Generally the altitude at which the pressure in the question is experience is

A =  10\ km

Thus the pressure altitude is  A =  10\ km

What do you mean by kinetic energy and potential energy ?
Verizon [17]

  • Kinetic Energy of an object is the measure of the work an object can do by virtue of its motions..

  • Formula - KE = 1/2 mv^2

  • Where KE is the kinetic energy, m is the body’s mass, and v is the body’s velocity.

  • Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts..

  • Formula - W = mgh

Where,

. m is the mass in kilograms

. g is the acceleration due to gravity

. h is the height in meters
