Determine the speed, wavelength, and frequency of light from a helium-neon laser as it travels through quartz. The wavelength of the light from the laser is 632.8 nm in air and the index of refraction of quartz is 1.458.

Which statement best describes how private industry decides where to spend the money on research and development

Newtons view of arrangement of the universe. don't copy from anywhere.

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
