Q:

A passage is given with 5 questions following it. Read the passage carefully and choose the best answer to each question out of the four alternatives.


The quest to find life outside the solar system got a big boost with the discovery of seven Earth-size extra-solar planets, or exoplanets, orbiting a dwarf star about 40 light years away. Unlike earlier discoveries of exoplanets, all seven planets could possibly have liquid water — a key to life as we know it on Earth — with three planets having the greatest chance. This is by far the largest collection of Earth-like planets in the habitable 'Goldilocks' zone of a star — neither too close nor too far from a star, which raises the possibility of liquid water being present on the surface. Only Earth has liquid water in the solar system. Since the dwarf star is much cooler than the Sun, the dimming of light each time a planet passes or transits before the star could be easily recorded from Earth unlike in cases when planets transit a Sun-like bright star. Since the initial discovery of three planets was made using the Chile-based Transiting Planets and Planetesimals Small Telescope, the exoplanet system is called TRAPPIST-1.

 

What is the 'Goldilocks' zone?

A) It is a mythological place about stars and planets B) That place on a planet which has lowest possibility of liquid water.
C) The correct distance of a planet from its star to have possibility of having liquid water D) That place on a planet which has the right amount of sunlight
 
Answer & Explanation Answer: C) The correct distance of a planet from its star to have possibility of having liquid water

Q:

Write a program for matrix multiplication in c

Answer

#include <stdio.h>


int main() {


  int a[5][5], b[5][5], c[5][5], i, j, k, sum = 0, m, n, o, p;


  printf( "\nEnter the row and column of first matrix" );


  scanf( "%d %d", &m, &n );


  printf( "\nEnter the row and column of second matrix" );


  scanf( "%d %d", &o, &p );


  if(n!=o) {


      printf( "Matrix mutiplication is not possible" );


      printf( "\nColumn of first matrix must be same as row of second matrix" );


  }


  else {


      printf( "\nEnter the First matrix" );


      for( i=0; i<m; i++ )


      for( j=0; j<n; j++ )
