Question 2 ; The Venus flytrap (Dionaea muscipula) is a carnivorous plant native to the East Coast of the United States. The plant uses rapid electrical signaling to close its leaf traps when triggered by an insect. This signaling generates action potentials like those in human nerve and muscle cells. The figure shows a trap’s action potential in green, and its corresponding magnetic field in blue (Fabricant et al., 2021). Such measurements of plant magnetic fields could be used in future plant diagnostics, just as MRIs are used in medical imaging today. If the resistance (R) of the trap is 0.97 x 106 Ω, and the action potential is V = 9 x 10-3 V, what is the current (I)? Show your calculations below and give your answer to two significant figures with the units. Hint: use Ohm’s law: I = V/R, substitute the given values to find the current (I) in amperes (A).

(Figure 1) shows a mass spectrometer, an analytical instrument used to identify the various molecules in a sample by measuring their charge-to- mass ratio q/m. The sample is ionized, the positive ions are accelerated (starting from rest) through a potential difference AV, and they then enter a region of uniform magnetic field. The field bends the ions into circular trajectories, but after just half a circle they either strike the wall or pass through a small opening to a detector. As the accelerating voltage is slowly increased, different ions reach the detector and are measured. Consider a mass spectrometer with a 200.00 mT magnetic field and an 8.0000 cm spacing between the entrance and exit holes. igure + AV d Detector Part A To five significant figures, what accelerating potential difference AV is required to detect the ion O,?
