Answer-1
Pseudo-Code:
1.Read array of n integers. (number[n]) /n is number of integers to be sorted
/Sorting Begins
2.for i (0->n-1) cfw_
for j(i+1->n-1) cfw_
if number[i]<number[j] cfw_
Swap number[i] and number[j].
/Sorting ends.
3.Print new array.
C

In ABC (using Pythagoras theorem)cfw_C being 90
( BC )2+ ( AC )2=( AB )2
( 5 )2 + ( x )2 =( y )2

Now, In A D C using Pythagoras theorem)cfw_C being 90
( CD )2 + ( AC )2= ( AD )2
( 7 )2 + ( x )2=( z ) 2
49+ ( x )2=( z

As we know graph for (x)^2 is parabola facing upward
As PQR is a triangle being perpendicular at P and PR | X-axis. So, triangle will look like :
So we can see y-cordinate of P= y-cordinate of R
Similarly, x-cordinate of P= x-cordinate of Q
Start with placing P.
Between these boundary lines, there are:

ANSWER
All matters are made up of particles called atoms. Atoms are basic building block.
The basic characteristics of atoms are:
Atoms cannot be divided further chemically. They consist of protons, neutrons, and
electrons.
Mass Number =n p + nn
ne =n p=
For ice:
Heat required for bringing ice from -10C to 0C
Q=m c t
o
o Q = (50)*4.186 *(0-(-10)
o Q = 2093 J
Heat required for melting ice
Q=m L
o
o Q = (50)*334
o Q = 16700 J
Let final temperature of mixture is TC. Then heat required to make water at TC
