Calculate the number of photons emitted each second from a laser pointer. the 17.7 milliwatt laser pointer is green, with a wavelength of exactly 532 nm. note: to input large numbers (scientific notation) into canvas, you will need to use "e" for example, 1 billion > 1e9 note: required precision is 2%.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
