Q1. Two wires, each 28.15 cm long, are connected to two separate 9.00 V batteries as shown in the figure. The resistance of the first wire is 5.00 Ω, and that of other wire is unknown (R). If the separation between the wires is 4.55 mm, what value of R will generate a force of magnitude 2.47x10-5 N between them?
Q2. With one flap of its wings, a butterfly can push a total of 3,000 cm3 of air to keep the butterfly flying. If the mass of the butterfly is 12 g, at what acceleration?
