If two forces are acting on an object , one is 25N west, and the other is 50N east. Calculate the net force.

Explanation:

Since the forces are only in the x-direction, you could just add the two forces. The West is to the left, so it would be -25N with the negative sign indicating direction. The East is to the right, so that would be +50N.

50 + (-25) = 25N to the right or the positive i-hat direction

what are the options.

explanation:

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask
