On a vacation flight, you look out the window of the jet and wonder about the forces exerted on the window. Suppose the air outs

user100 [1]

Answer:

A) $\Delta P = 14512.5 Pa = 14.512 kPa$

B) F = 1632.65 N

Explanation:

Given details

outside air speed is given as $v_2 = 150 m/s$

since inside air is atmospheric , $v_1 = 0 m/s$

a) By using bernoulli equation between outside and inside of flight

$P_1 + \frac{1}{2} \rho v_1^2 + \rho gh = P_2 + \frac{1}{2} \rho v_2^2 + \rho gh$

$\Delta P = \frac{1}{2} \rho v_2^2 - \frac{1}{2} \rho v_1^2$

$\Delta P = \frac{1}{2} \rho[ v_2^2 -v_1^2]$

$\Delta P = \frac{1}{2} 1.29 [ 150^2 - 0^2]$

$\Delta P = 14512.5 Pa = 14.512 kPa$

b) force exerted on window

Area of window $= 25\times 45 = 1125 cm^2 = 0.1125 m^2$

We know that force is given as

$F = P\times A$

$F = 14512.5 \times 0.1125$

F = 1632.65 N

What is the force weight of a jaguar who jumps 3 meters to a tree branch with 2670 J of work?

fgiga [73]

Answer:

$we \: know \: energy \: = \: force \: \times distance \\ e = f \times d \\ so \: f \: = \frac{e}{d} \\ so \: th \: force \: here \: = (\frac{2670}{3}) newton \\ = 890newton$

Oz discusses his work in the circus in the wonderful wizard of oz. he tells them about the ventriloquists in the circus. what is

iren [92.7K]

a person who alters their voice to make it seem as though the sound is coming from somewhere else, typically a puppet is a ventriloquist.

<h3>Which ventriloquist was the best?</h3>

Jimmy Nelson, an American ventriloquist who performed on television in the 1950s and 1960s, was born on December 15, 1928.

<h3>What makes it a ventriloquist?</h3>

The incorrect but long-held notion that the voice came from the stomach is explained by the word ventriloquism's Latin roots, ventri (belly) and loquor (to talk).

<h3>Why is a ventriloquist good?</h3>

Making your puppet seem lifelike and honing your voice are essential for becoming a competent ventriloquist. To divert attention from yourself, keep moving the body, arms, and head of the creature. To assist people forget that your puppet is actually you, try to make the character as different from you as you can.
