a block weighing 15.0N is resting on a flat surface and a horizontal force of 3.0N is acting on it. calculate the frictional 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

If the wheels lock when braking suddenly the vehicle: a: loses traction b: lose steering wheel ability c: gain speed slightly d: gain steering ability

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
