Explanation:

This is not so much a mathematical issue as a case study, because the response will inevitably require us to test the special Columbic shuttle disaster scenario. I would suggest that you read this in detail and present the points accordingly. Here I give as many points as I think are relevant.

The failure of a space program is definitely a complex situation, more than a simple binomial distribution. It's definitely not as simple as repeating the flip of a coin. There are several coherent factors and situations that govern the overall coordination and execution of such an event. The problem is, those who are running a project like this are still making a trade off,It is never the case that they sealed the lid on any chance of failure between multiple parameters. You try to do something, but often, as is the case above, the potentially dangerous situation is impossible or uncontrollable. Since the root cause of failure, which is dried out tiles that can not withstand heat and water, it appears that owing to the constant use of the shuttle the head architects have not foreseen this.

Answer:

Following are the proving to this question:

Explanation:

\frac{D_1}{D} = \frac{1}{(2f(\frac{l}{D}))^{\frac{1}{4}}}

using the energy equation for entry and exit value :

\to \frac{p_o}{y} +\frac{V^{2}_{o}}{2g}+Z_0  = \frac{p_1}{y} +\frac{V^{2}_{1}}{2g}+Z_1+ f \frac{l}{D}\frac{V^{2}}{2g}

where

\to p_0=p_1=0\\\\\to Z_0=Z_1=H\\\\\to v_0=0\\\\AV =A_1V_1 \\\\\to V=(\frac{D_1}{D})^2 V_1\\\\\to V^2=(\frac{D_1}{D})^4 V^{2}_{1}

         = (\frac{1}{(2f (\frac{l}{D} ))^{\frac{1}{4}}})^4\  V^{2}_{1}\\\\

         = \frac{1}{(2f (\frac{l}{D})  )} \  V^{2}_{1}\\

\to \frac{p_o}{y} +\frac{V^{2}_{o}}{2g}+Z_0  =\frac{p_1}{y} +\frac{V^{2}_{1}}{2g}+Z_1+ f \frac{l}{D}\frac{V^{2}}{2g} \\\\

\to 0+0+Z_0 = 0  +\frac{V^{2}_{1} }{2g} +Z_1+ f \frac{l}{D} \frac{\frac{1}{(2f(\frac{l}{D}))}\ V^{2}_{1}}{2g}   \\\\\to Z_0 -Z_1 = +\frac{V^{2}_{1}}{2g} \ (1+f\frac{l}{D}\frac{1}{(2f(\frac{l}{D}) )} )  \\\\\to H= \frac{V^{2}_{1}}{2g} (\frac{3}{2}) \\\\\to  \frac{V^{2}_{1}}{2g} = H(\frac{3}{2})

Lady bird [3.3K]

Answer:

The program to this question as follows:

Program:

Lemon= float(input('Enter lemon juice value in cups: ')) #defining float variable and input value by user

Water= float(input('Enter water value in cups: ')) #defining float variable and input value by user

Agave= float(input('Enter agave nectar value in cups: ')) #defining float variable and input value by user

Serve= float(input('enter serving value: '))  #defining float variable and input value by user

print ('Lemonade ingredients - yields',Serve,'servings',) #print value

print (Lemon,'cups in lemon juice',) #print value

print (Water,'cups in water',) #print value

print (Agave,'cups in agave nectar',) #print value

Output:

Enter lemon juice value in cups: 2

Enter water value in cups: 3

Enter agave nectar value in cups: 2

enter serving value: 2

Lemonade ingredients - yields 2.0 servings

2.0 cups in lemon juice

3.0 cups in water

2.0 cups in agave nectar

Explanation:

In the above python code, four float variable "Lemon, Water, Agave, and Serve" is defined, which is the input function is used.  

  • The input function message is written that passes in function parameter, that accepts value in the above variables.  
  • In the next step, the print function is used, which prints the above user input values.
