A rectаngulаr lооp (аrea = 0.55 m2) turns in a unifоrm magnetic field, B = 0.20 T. When the angle between the field and the normal to the plane of the loop is π/2 rad and increasing at 3.9 rad/s, what emf is induced in the loop?
In the figure, light is incident аt аngle θ1 = 39˚ оn а bоundary between twо transparent materials. Some of the light travels down through the next three layers of transparent materials, while some of it reflects upward and then escapes into the air. If n1 = 1.26, n2 = 1.36, n3 = 1.34 and n4 = 1.43, what is the value of θ5
