3. The coefficient of kinetic friction between an object and the surface upon which it is sliding is 0.40. The mass of the object is 3,2 kg. What is the force of friction?

What will a positive and a negative charge do if they are separated from each other?

An object's buoyant force and weight mean the same thing.a. trueb. false

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
