A100-g coin sits on a horizontally rotating turntable. The turntable makes exactly 1.00 revolution each second. The coin is located 10 cm from the axis of rotation of the turntable. (a) What is the frictional force acting on the coin? (b) If the coin slides off the turntable when it is located more than 16.0 cm from the axis of rotation, what is the coefficient of static friction between the coin and the turntable?
Block 4 lecture 1 - Visual system 1. Name 5 structures outside the visual globe that contribute to vision Eyelids and eyelashes - protection Lacrimal gland - produce tears Frontal eye fields and eye muscles - three cranial nerves control eye movement - 3,4, and 6 Conjunctiva - membrane that covers the inner surface of the eyelids and the sclera highly vascular Conjunctivitis “pink eye” nfection resulting in blood vessel inflammation 2. List the 3 major layers of the visual globe and the structures contained within each layer Outer -----> inner Fibrous layer - sclera and cornea -----> Vascular layer - choroid - iris - ciliary bodies -----> Neural tunic - retina 3. Discuss how each of the following structures contributes to vision and Name one visua
