Which of the following is an example of facilitated diffusion?

A copper (Young's modulus 1.1 x 1011 N/m2) cylinder and a brass (Young's modulus 9.0 x 1010 N/m2) cylinder are stacked end to en

Nina [5.8K]

We have that for the Question, it can be said that the amount by which the length of the stack decreases is

$dl'=3.621*10^{-4}m$

From the question we are told

A copper (Young's modulus 1.1 x 1011 N/m2) cylinder and a brass (Young's modulus 9.0 x 1010 N/m2) cylinder are stacked end to end, as in the drawing. Each cylinder has a radius of 0.24 cm.

A compressive force of F = 7900 N is applied to the right end of the brass cylinder. Find the amount by which the length of the stack decreases.

Generally the equation for copper cylinder is mathematically given as

$dl=\frac{Flo}{yA}$

$dl=\frac{7900*3*10^-^2}{1.1*10^{11}*\pi(0.24*10^{-2})^2}$

$dl=1.19064778*10^-^4$

Generally the equation for brass cylinder is mathematically given as

$dl=\frac{7900*5*10^-^2}{9*10^{10}*\pi(0.24*10^{-2})^2}$

$dl=2.43*10^{-4}$

Therefore Total change in length

$dl'=1.191*10^-^4+(2.43*10^{-4})$

$dl'=3.621*10^{-4}m$

Why is gum bad for you

viva [34]

There are a lot of reasons why gum is bad for you but a main reason because if you make a bubble and swallow it you could choke. Another reason is because it breaks down your gums.

if the atmospheric pressure and temperature stay the same how would an increase in humidity affect takeoff performance

Mariulka [41]

High-density altitude and high humidity do not ever go hand in hand. If high humidity does exist, however, it exists wise to add 10 percent to your calculated takeoff distance and expect a reduced climb rate.

With a longer takeoff distance, the air exists less dense.

<h3>How do atmospheric temp pressure and rel humidity affects aircraft performance?</h3>

Several elements (altitude/pressure, temperature, and humidity) affect air density. A more elevated altitude, low-pressure area, higher temperature, and increased humidity all contain one effect: they lower the density of the air. And as a consequence of that: a decrease in aircraft and engine performance.

Humidity reduces the implementation of most aircraft, not only because of its effect on the wings but also effect on the engines. Humidity contains a significant effect on the path of plane flies. This exists due to the weight of the air when it exists in humid.
