A 0.500-kg brass weight is swung horizontally at the end of a cord 1.25 m long at the rate of 1.50 revolutions per second. Calculate the centripetal force on the brass weight.

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?

The force will determine the acceleration.

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.
