Consider a runner traveling with an initial velocity of 1.9 m/s in the positive direction accelerates at a constant rate of 1.2 m/s2 for a time of 3 seconds. what is his velocity at the end of this time?

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.
