(x – 1, y + 3) = (2, x + 4)

So, x - 1 = 2

x = 2 + 1 = 3

and y + 3 = x +4

y + 3 = 3 + 4

y + 3 = 7

y = 7 - 3

y = 4

X=3 and Y=4

Controls and regulates the amount of light entering the eye

Yogita Ingle 5 years, 11 months ago

Pupil The pupil is essentially a hole in the center of your iris that controls how much light enters the eye. It's size is controlled by the relaxing and contracting of the iris. When there is high light intensity, the pupil shrinks while it grows in low light intensity. This is to ensure there is enough light for vision without damaging the sensitive retina.

Meghna Thapar 5 years, 11 months ago

The function of the pupil is to allow light to enter the eye so it can be focused on the retina to begin the process of sight.

Split ring is used to change the direction of current after every half rotation while slip ring is used to make contact between the rotating coil and electric circuit...

4Thank You

Aarushi Gupta 5 years, 11 months ago

- Split rings are used in electric motors whereas slip rings are used in generators. - split rings are half circles whose inner side is insulted. They act as a commutator in motors. - slip rings also have insulated inner side but are circles.
