Answer:
Atlantis benefited from lessons learned in the construction and testing of Enterprise, Columbia and Challenger. ... The Experience gained during the Orbiter assembly process also enabled Atlantis to be completed with a 49.5 percent reduction in man hours (compared to Columbia).

Answer:
I would say false but I am not for sure
Answer:
// Program is written in C++
// Comments are used to explain some lines
// Only the required function is written. The main method is excluded.
#include<bits/stdc++.h>
#include<iostream>
using namespace std;
int divSum(int num)
{
// The next line declares the final result of summation of divisors. The variable declared is also
//initialised to 0
int result = 0;
// find all numbers which divide 'num'
for (int i=2; i<=(num/2); i++)
{
// if 'i' is divisor of 'num'
if (num%i==0)
{
if (i==(num/i))
result += i; //add divisor to result
else
result += (i + num/i); //add divisor to result
}
}
cout<<result+1;
}
Answer:
a) 180 m³/s
b) 213.4 kg/s
Explanation:
= 1 m²
= 100 kPa
= 180 m/s
Flow rate
![Q=A_1V_1\\\Rightarrow Q=1\times 180\\\Rightarrow Q=180\ m^3/s](https://tex.z-dn.net/?f=Q%3DA_1V_1%5C%5C%5CRightarrow%20Q%3D1%5Ctimes%20180%5C%5C%5CRightarrow%20Q%3D180%5C%20m%5E3%2Fs)
Volumetric flow rate = 180 m³/s
Mass flow rate
![\dot{m}=\rho Q\\\Rightarrow \dot m=\frac{P_1}{RT} Q\\\Rightarrow \dot m=\frac{100000}{287\times 293.15}\times 180\\\Rightarrow \dotm=213.94\ kg/s](https://tex.z-dn.net/?f=%5Cdot%7Bm%7D%3D%5Crho%20Q%5C%5C%5CRightarrow%20%5Cdot%20m%3D%5Cfrac%7BP_1%7D%7BRT%7D%20Q%5C%5C%5CRightarrow%20%5Cdot%20m%3D%5Cfrac%7B100000%7D%7B287%5Ctimes%20293.15%7D%5Ctimes%20180%5C%5C%5CRightarrow%20%5Cdotm%3D213.94%5C%20kg%2Fs)
Mass flow rate = 213.4 kg/s
