- Q = Qo e* (C36) d) The capacitor charge in the circuit below decays exponentially when the capacitor has an initial charge of Qo: URC. Give brief physics (not math!) explanations for the observation that the time constant (how long it takes to discharge) is proportional to both C and R. Why is the time constant proportional to R (i.e. why does it take longer when R is bigger)? Why is the time constant proportional to C (i.e. why does it take longer when C is bigger)? R Carrow_forwardHow do I know whether to use cos or sin? Please explain. Is there a trick or such to easily identify whether I need to use cos or sin?arrow_forward1. *Other space is mostly battery L =~ 1 mm (0.001 m) Question: What frequencies are allowed in a red laser pointer? v = c (speed of light: 300,000,000 m/s)arrow_forward
- A group of students using an oscilloscope determines that for one cycle of a sinusoidal wave there is 3.6 horizontal divisions and 4.5 vertical divisions. If the time/div knob is set to 5ms/div and the volts/div knob set to 0.2v/div. What is the peak to peak voltage of the waveform. A) 0.72 V B) 22.5 V C) 0.9 V D) 18 Varrow_forward3. You are still fascinated by the process of inkjet printing, as described in the opening storyline for this chapter [Check chapter Introduction of Chapter 22]. You convince your father to take you to his manufacturing facility to see the machines that print expiration dates on eggs. You strike up a conversation with the technician operating the machine. He tells you that the ink drops are created using a piezoelectric crystal, acoustic waves, and the Plateau-Rayleigh instability, which creates uniform drops of mass m = 1.25 × 10-8g. While you don't understand the fancy words, you do recognize mass! The technician also tells you that the drops are charged to a controllable value of q and then projected vertically downward between parallel deflecting plates at a constant terminal speed of 18.5 m/s. The plates are { = 2.25 cm long and have a uniform electric field of magnitude E = 6.35 × 10*N/C between them. Noting your interest in the process, the technician asks you, "If the position…arrow_forwardStopping potential (V) 7.0 6.0 5.0 4.0 3.0 2.0 1.0 f(10¹5 Hz) 0 0.50 1.0 1.5 2.0 2.5 3.0 Fig. 1 The graph in Fig. 2 shows the stopping potential as a function of the frequency of the incident light falling on a metal surface.
