In the circuit below, the voltage source is a 5 v power supply. the inductor is considered to be ideal (it has no internal resistance) and large (say, 1 henry). r1 = 2.5 ω and r2 = 2.5 ω . part a assume the switch had been closed for a long time. use the loop rule to determine the voltage drop across r2. nothing v request answer part b at the instant just after the switch was opened, what is the current though the inductor? nothing a request answer part c at the instant just after the switch was opened, what is the current though r2? nothing a request answer part d at the instant just after the switch was opened, what the current though r1? nothing a request answer part e at the instant just after the switch was opened, what the magnitude of the voltage drop across r1? nothing v request answer part f suppose r1 were replaced with a resistor with 10 times the resistance and the switch had been closed for a long time. what would the magnitude of the voltage drop across r1 be just after the instant in which the switch was opened?

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?
