Answer:
The correct answer is c
Explanation:
In these two different models of movement of the planets
Ptolemy raises the Earth as the center of the solar system
In the Copernicus system, it poses the Sun as the center of the solar system.
Copernicu's system was accepted for giving a simpler and more complete explanation of the problem
The correct answer is c
Heat, light, motion, sound can all be produced in a chemical reaction and could be considered forms of energy: thermal energy, electromagnetic energy, kinetic energy, and sound
Answer:
The near point of an eye with power of +2 dopters, u' = - 50 cm
Given:
Power of a contact lens, P = +2.0 diopters
Solution:
To calculate the near point, we need to find the focal length of the lens which is given by:
Power, P = 
where
f = focal length
Thus
f = 
f =
= + 0.5 m
The near point of the eye is the point distant such that the image formed at this point can be seen clearly by the eye.
Now, by using lens maker formula:

where
u = object distance = 25 cm = 0.25 m = near point of a normal eye
u' = image distance
Now,



Solving the above eqn, we get:
u' = - 0.5 m = - 50 cm
