the retina is a light-sensitive layer of tissue,and the eye uses it to create an image.
Explanation:
Classical Thermodynamics studies the relationships between the State functions of the system: i.e. Pressure, Temperature, Volume, Energy, Entropy etc. In classical thermodynamics we pretend that we don’t know anything about the microscopic constituents (atoms) of our thermodynamic system. We do not talk about concepts like microstates, or ensemble averages, since such concepts require a more fine-grained perspective of the universe.
Statistical Thermodynamics explores how particular microscopic elements of the structures can be statistically related to the functions of the state. Depending on the limit in which we are, these microscopic elements can be either classically or mechanically quantified. In the end, nearly all statistical thermodynamics are derived by summing up the microscopic properties to derive equations for the functions of the macroscopic state.
Answer:
Concave, +2D
Convex -2D
Explanation:
Power of a lens is the reciprocal of its focal length.
For lens of +50cm = 0.5m
Power of the lens = 1/0.5
Power of the lens = +2Dioptres
Since the focal length is positive, the lens is concave
For the lens of -50cm = -0.5m
Power = 1/-0.5
Power = -2D dioptres
Since the focal length is negative, the lens is convex
Answer:
MA of a lever is 2. It means the lever can lift a load of 2 times heavier than the effort
