Answer:
0.287
Explanation:
Design-stage uncertainty can be expressed as :
Ud = √ Uo^2 + Uc^2 ------ ( 1 )
where : Uo = 1/2( resolution value ) = 1/2 * 0.01 V = 0.005 V
Uc = √(0.10)^2 + (0.10)^2 + (0.15)^2 + (0.20)^2 = 0.287
back to equation 1
Ud = √ ( 0.005)^2 + ( 0.287 )^2 = 0.287
The likely difference between urban planning for a very old city and urban planning for a new community built very recently is: "Urban planning for the very old city will present a more difficult array of problems." (Option B)
<h3>Why will Urban planning for a very old city present a
more difficult array of
problems?</h3>
Urban planning, also known as town planning, infrastructure planning, regional planning, or rural planning, is a technical and political process that focuses on the design and development of land use and the built environment, including air, water, and the infrastructure that passes through and out of urban areas, such as transportation, communications, and distribution networks, as well as their accessibility.
Cities that are poorly designed and managed also introduce new hazards that threaten to destroy present development benefits. Natural disasters can become disasters due to a lack of suitable infrastructure and services, dangerous housing, and inadequate and bad health care.

Ceramics must be heated in order to harden the clay and make it durable. The tool used to heat the clay is called a Kiln.
<h3>What happens when ceramic is heated?</h3>
Cristobalite is a silica polymorph that is used in ceramics. Quartz particles in porcelain can change into cristobalite during burning. This has effects on the fired matrix's thermal expansion. When there is a high level of vitrification or a shape is unstable during the firing of ceramic ware, warping occurs.
Ceramic items are porous, brittle, and rigid. They are thus employed in the production of glass, ceramics, cement, and bricks. Additionally, ceramics are employed extensively in gas turbine engines. Artificial bones and dental implants are both made of bio-ceramics.
Any of the several tough, fragile, heat- and corrosion-resistant materials created by sculpting and then heating an inorganic, nonmetallic material like clay to a high temperature are known as ceramics.
In order to solidify the clay and make ceramics durable, heat must be applied. A kiln is the name of the device used to heat clay.

Answer:
<em><u>Door knob</u></em>
Explanation:
When the knob on one side of the door is turned, the shaft retracts the spring-loaded latch that holds the door closed. Without the knob in place, more force would be needed to turn the shaft and retract the latch.
Answer:
Without Recursives
// Program is written using C++
// Comments are used for explanatory purpose
int main()
{
// Declare integer number, n
int n;
cout<<"Enter number of starts to print"
cin>>n;
// Iterate through to print * pattern
for(i=n; i>0;i--)
{
for(j=n; i>j-1;j--)
{
cout<<"*";
}
cout<"\n";
}
for(i=0; i< n; i++)
{
for(j=0;j<=i;j++)
{
cout<<"*";;
}
cout<"\n";
}
return 0;
}
Using Recursive
#include <iostream>
using namespace std;
void printStars(int lines);
int main()
{
// prompt the user to enter a number
int lines;
cin>> lines;
printStars(int lines);
return 0;
}
void printStars(int lines)
{
if (lines < 1)
return;
// to print the stars of a particular row
if (i <= lines)
{
cout << "* ";
// recursively print rest of the stars
// of the row
printPatternRecur(lines, i + 1);
}
else
{
// change line
cout << endl;
// print stars
printPatternRecur(lines-1, 1);
}
}
