Question

A o c ol of w has 25 turns and has a radius of 0.075 m. The coil is loca van magnetic field whose behavior is shown on the graph. At all times magnetic field is directed at an angle of 75" relative to the normal to the plane of a what is the average of induced in the coil in the time interval from t = 5.00 s to 7.5 E -Nd 0 at a) -18 mv b) 49 mv c) -92 mv d) - 140 Mv The angle of incidence 6- A.B -ABCoso a) is always less than the angle of reflection. b) may be greater than, less than or equal to the angle of reflection. c) is always greater than the angle of reflection. d) must equal the angle of reflection. Light arriving at a concave mirror on a path parallel to the axis is reflected a) back parallel to the axis. b) back on itself. c) through the focal point. d) through the center of curvature An object is located 2.6 m in front of a plane mirror. The image formed appea a) on the mirror's surface. b) 1.3 m in front of the mirror. C) 1.3 m behind the mirror's surface. d) 2.6 m behind the mirror's surface.

Answer 1

1) E = -adde dt : - Nalbac figure is not given. d.) must equal the angle of reflection by Licle (snells law) througth Focal point 4 d) 2.6m behind the mirror.
