An experimental device uses electrical energy to accelerate a projectile motion. Using dimensional analysis alone, what can you determine about how the accelerating force, F, depends on the current, I, if the only other quantities which need to be considered are the thickness of the rails, d, the distance between the rails,D, and the constant known as the permeability of free space, o. 2 ML The value of µo is 47 × 10-7 N/A², so [µ0] = . Q

the supplied powers is equal to zero. 35. The circuit depicted in Fig. 2.34 contains a dependent current source; the magnitude and direction of the current it supplies are directly determined by the voltage labeled vj. Note that therefore iz = -3v1. Determine the voltage 100 mA. Vi if v2 33i2 and iz 3v1 Sa FIGURE 2.34 +.

A car battery is rated at 1,020 AH (i.e., amps x hours). Calculate the number of coulombs this is equivalent to. Your Answer:

Find the ratio of the diameter of copper to tungsten wire, if they have the same resistance per unit length (as they might in household wiring).   dCu/dW =
