A housefly walking across a surface may develop a significant electric charge through a process similar to frictional charging. Suppose a fly picks up a charge of 52 pC. Part A How many electrons does it lose to the surface it is walking across

Gunpowder residue is most likely to show up where on a shooters hands

In the first law of thermodynamics, triangle e=q-w, what does q stand for

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
