- please help with all parts, show work and please at the end list the answers to all parts.What inductance must be connected to a 20 pF capacitor in an oscillator capable of generating 590 nm (i.e., visible) electromagnetic waves? Number i UnitsA rectangular loop of wire is moving toward the bottom of the page with a speed of 0.020 m/s. The bottom part of the loop is outside the region. The field strength inside the region is 2.4 T and the magnetic field outside the region is and the magnetic field outside the region is zero. The width of the loop is 0.080 m and the length is 1.0 meter. What is the current induced in the wire if the resistance of the loop is 0.12 ohm?
- 2. A capacitor of 12µF is charged by a 30 V battery. Afterwards, the capacitor is disconnected from the battery and connected to an inductor with L = 2H. a. What is the angular frequency? b. What is the initial charge on the capacitor? What is the charge on the capacitor at 0.05 s? с.Solar cells generate a potential difference when exposed to sunlight. In an experiment, you wish to charge a rechargeable battery by connecting it in series to an array of solar cells. You perform the experiment outdoors, in direct sunlight, when the intensity of solar radiation is 1000 W/m². However, your solar cells only have an efficiency of 11% (that is, only 11% of the sunlight power transmitted to the solar cells is delivered to the rechargeable battery). While the circuit is connected, you measure at one instant the potential difference across the battery to be 5.30 V and the current in the circuit to be 0.27 A. What is the area of the array of solar cells? m2A loop of wire with radius rr = 0.072 m is in a magnetic field of magnitude B. The magnetic field is perpendicular to the plane of the loop. B changes from B1 = 0.39 T to B2 = 7.5 T in Δt = 1.5 s at a constant rate. A) Express the magnitude of the average induced electric field, E, induced in the loop in terms of ΔΦ , r , and Δt. --> E = ? (formula with symbols) B) Calculate the numerical value of E in N/C.
