Make a labelled diagram of a vertical section of a mammalian eye. Describe what happens when one looks from a distant object to a near one. Explain the functions of rods and cones.

What happens to the image distance in the eye when we increase the distance of an object from the eye ?

A thin uniform copper rod of length l and mass m rotates uniformly with an angular velocity omega in a horizontal plane about a vertical axis passing through one of its ends. Determine the tension in the rod as a function of the distance r from the rotation axis. Find the elongation of the rod.

Draw a diagram of the human eye as seen in a vertical section and label the parts which suits the following functions/descriptions : The region of distinct vision.

Draw a diagram of the human eye as seen in a vertical section and label the parts which suits the following functions/descriptions : The fluid present in the anterior part of the eye in front of the eye lens.

What type of organs eye of an Octopus and that of a human called? Give another example from the animal group and one from the plants of such organs. Name and explain the evolutionery process they exhibit.

A half metre scale is pivoted about a horizontal fiictionless pin through one end as shown in Fig. The scale is released from rest in a vertical position. At the instant when the scale is horizontal what is (i) its angular speed and (ii) the magnitude of the angular acceleration.(Given length of rod =1/2 m)

Draw a diagram of the human eye as seen in a vertical section and label the parts which suits the following functions/descriptions : The outermost transparent layer in front of the eye lens.

Draw a diagram of the human eye as seen in a vertical section and label the parts which suits the following functions/descriptions : The layer which prevents reflection of light.

A concave mirror is used for image formation for different positions of an object. What inferences can be drawn about the following when an object is placed at a distance of 10 cm from the pole of a concave mirror of focal length 15 cm? (a) Position of the image (b) Size of the image (c) Nature of the image Draw a labelled ray diagram to justify your inferences.

An amusement park ride consist of a large verticle cylinder that spins about its axis first fast enough that any person inside is held up againest the wall when the is mu_(s) and the radius of the cylider is R a. Shown that maximum period of revolation neccessary to keep the person from falling is T = (4 pi^(2) mu_(s) R //g)^(1//2) b. Obtain a numerical value for T taking R = 4.00m and mu_(s) = 0.400 . How many revolations per minute does the cylinder make? c. If the rate of revolation of the cylinder is make to be some what larger what happens to the magnitude of each one of the forces acting on the person ? What happens to the motion of the person ? d. If instead the cylinder rate revolution is made to be somewhat smaller what happens to the magnitude and what happens to the motion of the person ?
