Nmr: a poor digital resolution will result in loss of some of the fine structure of an nmr signal. to increase the digital resolution, we need either :

1) maintain the same number of data points but reduce the spectral width or

2) maintain the spectral width but increase the number of data points

which method (1 or 2) would be better for achieving a better signal to noise (s/n) ratio and why?

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.
