The area of the velocity time graph gives displacement of the body true or false?
The answer this is true.
Answer:
Minimum thickness will be 100 nm
Explanation:
We have given refractive index is n = 1.5
Wavelength of the light incidence 
= 600 nm
We have to find the smallest thickness of the film so that there will be minimum light reflect
For minimum thickness of non reflecting film
, here t is thickness, is wavelength and n is refractive index
Putting all values 
So minimum thickness will be 100 nm
Explanation:
The energy stored in coal is directly form the sun which is solar energy. This energy are preserved in carbon atoms and they originate from the life processes of a plant.
- Plants carry out photosynthesis and produce their energy by this process.
- Green plants have special adapted structures by which they trap solar energy from the sun and use it to produce their own food.
- The food is used by plant for nutrition and life activities.
- In essence the solar energy is converted to chemical energy in plants.
- To form coal, when plants are rapidly buried their organic matter is preserved from decay by combination with oxygen.
- More burial preserves the complex molecules that have stored during photosynthesis.
- The carbon eventually aggregates for coal.
