Please answer all parts SHOWING ALL STEPS CLEARLY EXPLAINING THE CONCEPTS and make sure all are 100% correct solutions. Do NOT use calculus (Integration, Cross product, etc.) to solve any of them. Thank you very much!

At t = 0 the switch is closed in a BL circuit consisting of a battery, an inductor, and a single resistor, arranged in series. If L = 4mH, R = 39, and 8 = 6 V, what is the voltage across the resistor at time t = 2ms? (1) 4.7 V (2) 1.3 V (3) 3.9 V (4) 2.1 V (5) 0.7 V Three resistors, all with an identical unknown resistance are arranged as shown in the gure, where 8 = 120 V and L = 4 H. Immediately after switch S is closed, the current through R1 is 12 Amperes. What is the current through R1 after a long time has passed? 1 16A 2 12A 3 6A 4 24A 5 0A Orienting a radio's antenna vertically so that the antenna is parallel to the y-axis allows you to clearly receive tunes coming from your favorite FM radio station. You know that the broadcast of the radio signal comes from a transmitting tower located due East of your location. Which of the following choices presents a possible orientation for the components of the radio signal detected at your location? (1) the electric field oriented along y-axis, magnetic field along North /South (2 the electric field oriented along East / West, the magnetic field along y-axis 3 the electric field oriented along y-axis, magnetic field along East /West the electric field oriented along North/South, magnetic field along East / West the electric field along North/South, magnetic field along y-axis.A mystery object is dropped through a single loop made out of a conducting wire. While the object is moving towards the loop, a clock-wise current is induced in the loop, as viewed from above. Which of the following conclusions are accurate about the object and its orientation? 1 the object is magnetic, with its South Pole face closest to the loop '17) 2 the object is magnetic, with its North Pole face closest to the loop 3 the object is magnetic, but there is not enough information to identify its magnetic poles 4 the object is not magnetic 5 there is not enough information to identify if the object is magnetic. CW The current in the straight wire is decreasing. What are the directions of the I current induced in loop A, that encircles the wire, and in loop B? List the direction of the current induced in loop A rst, followed by the direction of the current induced in loop B. zero, clockwise counterclockwise, clockwise clockwise, clockwise counterclockwise, counterclockwise clockwise, counterclockwise mrPWNbl An electron and an alpha particle (qOE = +2qproton) are moving with equal speeds of 3.5 X 106 m/s in the directions shown. What is the magnitude and direction of the net magnetic eld at the location marked x? (1) B' = (7.65 x 10-9 T) 2 (2) B' = (2.03 >
