Q1. A 484g oscillator has a speed of 121 cm/s when its displacement is 2.10 cm and 56.0 cm/s when its displacement is 7.00 cm. What the max speed of the oscillator?
Q2. A capacitor is connected across the terminals of an ac generator that has a frequency of 370 Hz and supplies a voltage of 15 V. When a second capacitor is connected in parallel with the first one, the current from the generator increases by 0.27 A. Determine the capacitance of the second capacitor. Note: The ac current and voltage are rms values and power is the average value unless indicated otherwise.
