A 300N weight is held suspended in equilibrium by two ropes. The first rope is at 37° from the positive x-axis and the second rope is to the negative x-axis. What are the forces F1 and F2 respectively on the ropes?

How many molecules are present in 3 mols of silicon dioxide (sio2)?

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively
