black_mamba_eteeap Posted July 27, 2014 Share Posted July 27, 2014 A certain location has barometric reading of 720 mm Hg and the gravitational acceleration is 9.2 m/s2 . If the temperature of mercury is 9 degree Celsius at which density is 12,850 kg/m3, compute the atmospheric pressure. Link to comment Share on other sites More sharing options...
studiot Posted July 27, 2014 Share Posted July 27, 2014 What have you done so far? Why do you think this has anything to do with the First Law? Link to comment Share on other sites More sharing options...
black_mamba_eteeap Posted July 27, 2014 Author Share Posted July 27, 2014 It has nothing to do with First law. Im sorry. Im deriving the formula for gravitational acceleration. Link to comment Share on other sites More sharing options...
studiot Posted July 27, 2014 Share Posted July 27, 2014 It would be less puzzling to us, and therefore easier to help you, if you explained further. Your original question specifically asks for the atmospheric pressure. What do you think this has to do with gravitational acceleration? Link to comment Share on other sites More sharing options...
Sensei Posted August 4, 2014 Share Posted August 4, 2014 Im sorry. Im deriving the formula for gravitational acceleration. In this thread I showed how to measure gravitational acceleration, at home doing experiment: http://www.scienceforums.net/topic/84336-if-pi-ratio-was-squared-and-98-mss-how-would-this-change-the-whole-of-science/?p=815752 1 Link to comment Share on other sites More sharing options...
