Question 16 (2 points) The electricity coming from power plants into a home is alternating current (AC). This is means that the direction of the current flowing in a circuit is constantly switching back and forth. In Canada, the voltage, V, can be modelled as V = 170 sin(120at ) where t is the time in seconds. a. To the nearest thousandth of a second, what is the period for this scenario? (enter your value in blank 1). b. Suppose the current is flowing for one hour. To the nearest whole number, how many complete cycles will occur in that time. In this calculation, use the exact value from part a) and not the rounded answer. (enter your value in blank 2). Blank # 1 Blank # 2
