The following figure shows a manometer filling with mercury connected to a tank filling with a liquid and gas methane. Calculate the gas pressure, in cm Hg and Pa. (Density of mercury =13.6×10³kgm¯³). (atmospheric pressure =76Hg) (g=10N kg ¯¹)​

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
