Two stretched cables both experience the same stress. The first cable has a radius of 3.2x10-3 m, and is subject to a stretching force of 250 N. The radius of the second cable is 5.2x10-3 m. Determine the stretching force on the second cable.

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.

What type of nuclear decay causes the atomic number of an element to increase by 1?

Based on the concept of the wave-like nature of light, huygens' theory of light postulates that the more light was "bent" by a substance the slower it would move while traversing across that substance. a) deflection b) interference c) refraction d) resonance
