Chemistry
Trichloroethane, C2H3Cl3, is the active ingredient in aerosols that claim to stain-proof men's ties. Trichloroethane has a vapor pressure of 100.0 mm Hg at 20.0 C and boils at 74.1 C. An uncovered cup (1/2 pint) of trichloroethane (d=1.325 g/mL) is kept in an 18-ft3 ...

hello ok i realized what you meant. =) An object of mass M = 921 g is pushed at a constant speed up a frictionless inclined surface which forms an angle θ = 50o with the horizontal. The normal force acts perpendicular to the slope. The slope is the x-component and y ...

That is weird I had posted a question before!! lol anyways the question was; All forces in this problem act on an object along the same axis. Two forces have values -5N +10N respectively. What should be done to bring the system into mechanical equilibrium??? add a third force ...
