If the spacing between the lines is 2000 nm, and the angle of the second-order ray is 48.5°, what is the wavelength of the light? a. 1500 nm b. 1000 nm c, 750 nrn d. 2000 nnm e. we can't determine the wavelength from the information.

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.)
