There is a function generator driving a series RC circuit. The function generator provides an AC current of I(t) = Io sin(2? f t), where Io = 2.50 mA is the current amplitude and the frequency f is f = 100. Hz. The resistor has a value of R = 4.7 K? and the capacitor value is C = 0.520 ?F. For this circuit:
What is the voltage amplitude across the resistor?
What is the reactance of the capacitor?
What is the voltage amplitude across the capacitor?
The graph below shows the voltage across the resistor R as a function of time. On the axes below sketch the voltage across the capacitor during the same time interval. (No graph supplied so maybe just a rough sketch of what it would look like)
The cannonball is fired at a speed of 53.0 and an angle of 31 above horizontal. A cannonball that was accidentally dropped hits the moat below in 1.40. How far from the castle wall does the cannonball hit ground.
Two loudspeakers are placed above and below each other and driven by the same source at a frequency of 4.50x10^2 Hz. An observer is in front of the speakers (to the right) at point O.
