Here are a number of statements concerning the refractive power of lenses. which of these statements are false? a. a positive refractive power means that a lens always creates an image that is larger than the object. b. two lenses with the same refractive power have the same focal lengths. c. a lens with a positive refractive power is a converging lens, whereas a lens with a negative refractive power is a diverging lens. d. two lenses with different refractive powers can have the same focal length. e. the fact that lens a has twice the refractive power of lens b means that the focal length of lens a is twice that of lens b.

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s. assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
