If a farsighted person has a near point that is 0.600 m from the eye, what is the focal length f2 of the contact lenses that the person would need to be able to read a book held at 0.350 m from the person's eyes? express your answer in meters.

f = 0.84 m

Explanation:

given,

near point of the distance from eye(di) = 0.60 m

focal length calculation = ?

distance he can read (d_o)= 0.350 m

now,

Using lens formula

f = 0.84 m  

The focal length of the lens f = 0.84 m

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

i think the answer is a, hope this : )
