Which force determines if an object is going to move or stay at rest? a. Friction Force
b. Normal Force
c. Applied Force
d. Net Force

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

Where do magnetic lines of force enter earth?

If anyone who can me with this hw? i would really appreciate it
