An optical fiber is made of glass with an index of refraction of 1.24. Assuming the fiber is surrounded by air, for what minimum angle of incidence (in radians) will light remain in the fiber

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
