A square loop of length a and resistance R, is
dropped from a height of h. A magnetic field exists
everywhere, perpendicular to the loop area which varies with height
according to:
Given:
a=8.3 m, R=2.3, h=0.7m,
=6.9T,

The drawing shows a bicycle wheel resting against a small step
whose height is h = 0.126 m. The weight and radius of the
wheel are W = 22.7 N and r = 0.357 m,
respectively. A horizontal force is applied to the
axle of the wheel. As the magnitude of increases, there
comes a time when the wheel just begins to rise up and loses
contact with the ground. What is the magnitude of the force when
this happens?...

Considering an RCL circuit where an inductor L = 1/2 H, a
resistance R = 6Ω, a capacitor C = 1/50 F and a source of e(t) = 24
sin (10t) volts are connected in series. At t = 0, the switch is
closed and the current starts to flow. Considering that the
capacitor has an initial voltage of 5 volts, thus,Vc (0)
= 5 V and V'c (0) = 0.
