Three forces act on an object, as indicated in the drawing. Force
has a magnitude of 21.0 newtons
(21.0 N) and is directed 30.0 to the
left of the "y axis. Force has a
magnitude of 15.0 N and points along
the axis. What must be the magnitude and direction (specified by the
angle # in the drawing) of the third
force such that the vector sum of the
three forces is 0 N?

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

snell's law

refractve index = sin incidence / sin refraction
