A360 nm thick oil film floats on the surface of the water. the indices of refraction of the oil and the water are 1.50 and 1.33, respectively. the surface of the oil is illuminated from above at normal incidence with white light. in the situation above, the two wavelengths of light in the 400 nm to 800 nm wavelength band that are most strongly reflected, in nm, are closest to:

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
