← A square conducting loop of side a moves to the right at a constant speed v. It passes through a region of width 2a in which there is a uniform magnetic field into the page, as shown in the figure. The loop enters the field at t = 0. Take the emf as positive when the induced current is anticlockwise. Which graph shows the induced emf ε against time, from t = 0 to t = 3a/v?
A travelling microscope is focused on a small mark on a table. A glass slab 3.0 cm thick (refractive index 1.5) is laid over the mark, and a layer of water 4.0 cm deep (refractive index 4/3) is poured on top of the slab, as shown in the figure. To see the mark sharply again, the microscope must be →
