What is the apparent depth of the reflection of the fish in the bottom of the tank when viewed at normal incidence? express your answer in centimeters. use 1.33 for the index of refraction of water. view available hint(s) hint 1. follow the path of light opened hint keep in mind that the light has to bounce from the bottom of the fish, down to the mirror, and then back up and out of the water to the viewer. first think of how far down the fish would appear if the index of refraction were the same in the water as out. you can use the law of reflection for a plane mirror to determine where the fish would appear without the water. then apply the correction for the real refraction due to the water.

Abaseball is thrown a distance of 20 meters. what is its speed if it takes 0.5 seconds to cover the distance

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]

The frequency of vibrations of a vibrating violin string is given by f = 1 2l t ρ where l is the length of the string, t is its tension, and ρ is its linear density.† (a) find the rate of change of the frequency with respect to the following. (i) the length (when t and ρ are constant) (ii) the tension (when l and ρ are constant) (iii) the linear density (when l and t are constant) (b) the pitch of a note (how high or low the note sounds) is determined by the frequency f. (the higher the frequency, the higher the pitch.) use the signs of the derivatives in part (a) to determine what happens to the pitch of a note for the following. (i) when the effective length of a string is decreased by placing a finger on the string so a shorter portion of the string vibrates df dl 0 and l is ⇒ f is ⇒ (ii) when the tension is increased by turning a tuning peg df dt 0 and t is ⇒ f is ⇒ (iii) when the linear density is increased by switching to another string df dρ 0 and ρ is ⇒ f is ⇒
