Answer:
Nanoparticles do hold out much environmental promise. The same reactivity that makes them harmful in the body also means they can break down dangerous chemicals in toxic waste – or anywhere, for that matter. And their use in electronics drastically reduces power demand, which could cut greenhouse gases.

Answer:
// program in C++.
#include <bits/stdc++.h>
using namespace std;
int main() {
// variable
int num;
cout<<"Enter the number between 20 and 98: ";
// read number
cin >> num;
while(num<20||num>98)
{
cout<<"Wrong input!!enter number between 20-98 only:";
cin>>num;
}
cout<<"The output is: ";
while(num % 10 != num /10)
{
// print numbers.
cout<<num<<" ";
// update num.
num--;
}
// display the number.
cout<<num<<endl;;
return 0;
}
Explanation:
Read a number from user and assign it to variable "num".Check if entered number is in between 20-98 or not.If input number is less than 20 or greater than 98 then ask again to enter a number between 20-98 until user enter a valid input.Then print the countdown from input number till both the digit of number are same.
Output:
Enter the number between 20 and 98: 99
Wrong input!!enter number between 20-98 only:12
Wrong input!!enter number between 20-98 only:93
The output is: 93 92 91 90 89 88
Enter the number between 20 and 98: 77
The output is: 77

Explanation:
The following code is written in Python. It uses the imports the turtle class in order to be able to draw a blue square with 100pixels per side and then a red circle with a diameter of 100 pixels that fits perfectly inside the square.
import turtle
t = turtle.Turtle()
#Make Square
t.fillcolor('blue')
t.begin_fill()
t.back(50)
for i in range(4):
t.forward(100)
t.left(90)
t.end_fill()
#Make Circle
t.forward(50)
t.fillcolor('red')
t.begin_fill()
t.circle(50)
t.end_fill()
