GO Figure 30-44a shows a wire that forms a rectangle (W = 20 cm, H = 30 cm) and has a resistance of 5.0 mΩ. Its interior is split into three equal areas, with magnetic fields
components Bz of the three fields with time t; the vertical axis scale is set by Bs = 4.0 μT and Bb = −2.5Bs, and the horizontal axis scale is set by ts = 2.0 s. What are the (a) magnitude and (b) direction of the current induced in the wire?

I am having trouble with this part of the lab.arrow_forwardMick and Rick are twins born on Earth in the year 2175. Rick grows up to be an Earth-bound robotics technician while Mick becomes an intergalactic astronaut. Mick leaves the Earth on his first space mission in the year 2200 and travels, according to his clock, for 10 years at a speed of 0.75c. Unfortunately, at this point in his journey, the structure of his ship undergoes mechanical breakdown and the ship explodes. How old is Rick when his brother dies?arrow_forward
