A point charge of charge q=45μC is placed in a uniform electric field of strength 78NCgoing to the right. The charge is then moved 4m at an angle of 30o below the horizontal to the right. What is the net work done on this charge?

Aneutron and a proton combine to form a nucleus. why does the mass of the nucleus differ from the sum of the masses of the individual nucleons?

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

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
