Answer 1

Answer:

Explanation:

#include <stdio.h>

//defining structure

struct Marks {

   int roll_no;

   char name[30];

   float chem_marks, maths_marks, phy_marks;

};

//main function

int main() {

 

   struct Marks marks[5];

   

   //Getting user input for info of the 5 students

   for(int i=0; i<4; i++){

 printf("Student %d\n",i+1);

       printf("Enter roll no. :\n");

       scanf("%d", &marks[i].roll_no);

       printf("Enter name :\n");

       scanf("%s",marks[i].name);

       printf("Enter Chemistry marks :\n");

       scanf("%f", &marks[i].chem_marks);

       printf("Enter Maths marks :\n");

       scanf("%f", &marks[i].maths_marks);

       printf("Enter Physics marks :\n");

       scanf("%f", &marks[i].phy_marks);

   }

   

   // Calculating and printing percentage for each student

for(int i=0; i<4; i++) {

    printf("Student %d\n",i+1);

    float percentage = (marks[i].chem_marks + marks[i].maths_marks + marks[i].phy_marks)/300.0*100;

    printf("Percentage : %f\n", percentage);

}

 return 0;

}

Answer:

In physics, power is the rate of doing work. It is the amount of energy consumed per unit time. The unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine)
