Vectors and the graphical method 21. A girl delivering newspapers travels three blocks west, four blocks north, and then six blocks east.
a. What is her resultant displacement?
b. What is the total distance she travels?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

In a given chemical reaction, the energy of the products is greater than the energy of the reactants. which statement is true for this reaction?

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.
