Answer:
meter
Explanation:
A nearsighted person uses concave lens.
Given -
Far point i.e distance of object 
meter
Distance of image is not given . Hence we will assume that the image can be formed at any distance. We will take "di" 
infinity
As we know
Substituting the given values in above equation, we get -
Hence, the focal length of the contact lens is equal to meter
"Proton" <span>determines the identity of an element!
So, option A is your answer!

Answer:
Carbohydrate is the first source of energy to human body. Glucose is the simple unit of carbohydrate which is used in respiration and produce ATP. When we eat food that contain carbohydrate, it convert into sugar units that are absorbed in small intestine. From here these sugar units travel to liver through blood where excess sugar is stored in the form of glycogen. When the body need energy this glycogen is converted to sugar through glucagon hormone and is used in respiration to produce ATP, which is necessary for the activities of humans.
