When a flask when full of air has a mass of 30.98 g. when the air is pumped out the flask has a mass of 30.72 g. find the mass of air in the flask before connecting to the vacuum pump

as technology advances, new experiments often expose problems in accepted theories. c

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

number of electrons for neutral cl

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
