Suppose that a parallel-plate capacitor has circular plates with radius r = 43 mm and a plate separation of 4.3 mm. suppose also that a sinusoidal potential difference with a maximum value of 120 v and a frequency of 72 hz is applied across the plates; that is,
v = (120 v) sin[2π(72 hz)t].
find bmax(r), the maximum value of the induced magnetic field that occurs at r = r.

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.
