An airplane flying at a velocity of 610 m/s lands and comes to a complete stop
Len [333]

A) The airplane slowed down. It states that the plane lands and come to a complete stop over a 53 second period.

B) It decelerates. The speed doesn't increase. It slows down.

C) The answer should be positive. Although the deceleration is slowing down the plane, it's not going at a negative speed.

D) The answer is 11.5m/s. I divided the velocity by the amount of seconds it takes to make a complete stop.

The gas co2 is diffusin at steady state through a tube 20 cm long having a diameter of 1 cm and containing n2 at 350 k . the tot
Marrrta [24]

The value is J = 1.71*10^-6 kmol/m^2.s

According to the given conditions we get,

The length the tube l= 0.20m

The diameter of the tube d= 0.01m

The total pressure inside the tube P= 101.32kPa

The partial pressure of CO2 at the first end is

P1= 456mm Hg = 60794.832 Pa

The partial pressure of CO2 at the other end is

P2= 76mm Hg = 10132.472 Pa

The temperature is T = 298 K

The diffusion coefficient D= 1.67* 10^-5 m^2/s

Generally the molar flux of CO2 is mathematically represented as

J= D{p1-p2} / R.T

Here R is the gas constant with value R= 8.314 j/kmol

So we get J= 1.71 * 10^-3 mol/m^2.sec

Please help me with this question
saul85 [17]
Okay well first let's find out the answer for the equation as given here;

4p^2 = 12p - 5

4p^2 - 12p + 5 = 0

4p^2 - 2p - 10p + 5 = 0

2p(2p - 1) - 5(2p - 1) = 0

(2p - 5)(2p - 1) = 0

p = 5/2, 1/2

now the question is asking what type of numbers are the solutions.

your answer is D) 2 rational solutions.

hope this helped (:
