<h3>What is food?</h3>
The substance that we intake for the body to charge up by giving nutrients is called the food.
Wheat is a staple food. We make chapati from flour obtained from the wheat grains.
The various contributions involved till the chapati is made is given below.
                  Take required amount of atta in a container
                                                      ↓
                     Add water accordingly to form a dough
                                                      ↓
                  Apply oil to make dough smooth for long time 
                                                     ↓
         Take small dough, make it a ball shaped and apply dry flour
                                                     ↓
                Roll it using rolling pin on the chapati maker plate
                                                     ↓
       After making it circular or any shape you want, place it on hot tawa
                                                     ↓
                                Bake it on both the sides
                                                    ↓
                                       Chapati is ready
Thus, the flow chart is made.

Solution:
(a) The work done by the spring is given by

where k is the elastic constant of the spring and 

 is the stretch between the initial and final position. Since x1=-8 in=-0.203 m and x2=5 in=0.127 m, we have

(b) The work done by the weight is the product of the component of the weight parallel to the inclined plane and the displacement of the cart:

where  the negative sign is given by the fact that 

 points in the opposite direction of the displacement of the cart, and where

therefore, the work done by the weight is
 
 
        
        
        
The refractive index of water is 

. This means that the speed of the light in the water is:

The relationship between frequency f and wavelength 

 of a wave is given by:

where v is the speed of the wave in the medium. The frequency of the light does not change when it moves from one medium to the other one, so we can compute the ratio between the wavelength of the light in water 

 to that in air 

 as

where v is the speed of light in water and c is the speed of light in air. Re-arranging this formula and by using 

, we find

which is the wavelength of light in water.
