32. An alternating current generator in the United Kingdom generates current with a frequency of 50 Hz.Suppose that initially, the current is at its maximum of 12 amperes. If the current varies in simpleharmonic motion over time, write a model for the current I (in amperes) as a function of the time t (inseconds).The angular displacement 0 (in radians) of a pendulum swinging through a small angle with limited airresistance and internal friction can be approximated by the simple harmonic motion models 0 = a sin otor 8 = a cos ot. The period T (time required for one back-and-forth swing) is given byT- 27where L is the length of the pendulum and g is the acceleration due to gravity. The maximum angulardisplacement is |a| and positive angles are taken to the right of the center position. Use this informationfor Exercises 33-34.
